What is a literature review? A literature review is a survey of scholarly sources on a specific topic. It provides an overview of current knowledge, allowing you to identify relevant theories, methods, and gaps in the existing research that you can later apply to your paper, thesis, or dissertation topic .

There are five key steps to writing a literature review:

Search for relevant literature
Evaluate sources
Identify themes, debates, and gaps
Outline the structure
Write your literature review

A good literature review doesn’t just summarize sources—it analyzes, synthesizes , and critically evaluates to give a clear picture of the state of knowledge on the subject.

Quick Run-through
Step 1 & 2

When you write a thesis , dissertation , or research paper , you will likely have to conduct a literature review to situate your research within existing knowledge. The literature review gives you a chance to:

Demonstrate your familiarity with the topic and its scholarly context
Develop a theoretical framework and methodology for your research
Position your work in relation to other researchers and theorists
Show how your research addresses a gap or contributes to a debate
Evaluate the current state of research and demonstrate your knowledge of the scholarly debates around your topic.

Writing literature reviews is a particularly important skill if you want to apply for graduate school or pursue a career in research. We’ve written a step-by-step guide that you can follow below.

Writing literature reviews can be quite challenging! A good starting point could be to look at some examples, depending on what kind of literature review you’d like to write.

Example literature review #1: “Why Do People Migrate? A Review of the Theoretical Literature” ( Theoretical literature review about the development of economic migration theory from the 1950s to today.)
Example literature review #2: “Literature review as a research methodology: An overview and guidelines” ( Methodological literature review about interdisciplinary knowledge acquisition and production.)
Example literature review #3: “The Use of Technology in English Language Learning: A Literature Review” ( Thematic literature review about the effects of technology on language acquisition.)
Example literature review #4: “Learners’ Listening Comprehension Difficulties in English Language Learning: A Literature Review” ( Chronological literature review about how the concept of listening skills has changed over time.)

Before you begin searching for literature, you need a clearly defined topic .

If you are writing the literature review section of a dissertation or research paper, you will search for literature related to your research problem and questions .

Make a list of keywords

Start by creating a list of keywords related to your research question. Include each of the key concepts or variables you’re interested in, and list any synonyms and related terms. You can add to this list as you discover new keywords in the process of your literature search.

Social media, Facebook, Instagram, Twitter, Snapchat, TikTok
Body image, self-perception, self-esteem, mental health
Generation Z, teenagers, adolescents, youth

Search for relevant sources

Use your keywords to begin searching for sources. Some useful databases to search for journals and articles include:

Your university’s library catalogue
Google Scholar
Project Muse (humanities and social sciences)
Medline (life sciences and biomedicine)
EconLit (economics)
Inspec (physics, engineering and computer science)

You can also use boolean operators to help narrow down your search.

Make sure to read the abstract to find out whether an article is relevant to your question. When you find a useful book or article, you can check the bibliography to find other relevant sources.

You likely won’t be able to read absolutely everything that has been written on your topic, so it will be necessary to evaluate which sources are most relevant to your research question.

For each publication, ask yourself:

What question or problem is the author addressing?
What are the key concepts and how are they defined?
What are the key theories, models, and methods?
Does the research use established frameworks or take an innovative approach?
What are the results and conclusions of the study?
How does the publication relate to other literature in the field? Does it confirm, add to, or challenge established knowledge?
What are the strengths and weaknesses of the research?

Make sure the sources you use are credible , and make sure you read any landmark studies and major theories in your field of research.

You can use our template to summarize and evaluate sources you’re thinking about using. Click on either button below to download.

Take notes and cite your sources

As you read, you should also begin the writing process. Take notes that you can later incorporate into the text of your literature review.

It is important to keep track of your sources with citations to avoid plagiarism . It can be helpful to make an annotated bibliography , where you compile full citation information and write a paragraph of summary and analysis for each source. This helps you remember what you read and saves time later in the process.

To begin organizing your literature review’s argument and structure, be sure you understand the connections and relationships between the sources you’ve read. Based on your reading and notes, you can look for:

Trends and patterns (in theory, method or results): do certain approaches become more or less popular over time?
Themes: what questions or concepts recur across the literature?
Debates, conflicts and contradictions: where do sources disagree?
Pivotal publications: are there any influential theories or studies that changed the direction of the field?
Gaps: what is missing from the literature? Are there weaknesses that need to be addressed?

This step will help you work out the structure of your literature review and (if applicable) show how your own research will contribute to existing knowledge.

Most research has focused on young women.
There is an increasing interest in the visual aspects of social media.
But there is still a lack of robust research on highly visual platforms like Instagram and Snapchat—this is a gap that you could address in your own research.

There are various approaches to organizing the body of a literature review. Depending on the length of your literature review, you can combine several of these strategies (for example, your overall structure might be thematic, but each theme is discussed chronologically).

Chronological

The simplest approach is to trace the development of the topic over time. However, if you choose this strategy, be careful to avoid simply listing and summarizing sources in order.

Try to analyze patterns, turning points and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred.

If you have found some recurring central themes, you can organize your literature review into subsections that address different aspects of the topic.

For example, if you are reviewing literature about inequalities in migrant health outcomes, key themes might include healthcare policy, language barriers, cultural attitudes, legal status, and economic access.

Methodological

If you draw your sources from different disciplines or fields that use a variety of research methods , you might want to compare the results and conclusions that emerge from different approaches. For example:

Look at what results have emerged in qualitative versus quantitative research
Discuss how the topic has been approached by empirical versus theoretical scholarship
Divide the literature into sociological, historical, and cultural sources

Theoretical

A literature review is often the foundation for a theoretical framework . You can use it to discuss various theories, models, and definitions of key concepts.

You might argue for the relevance of a specific theoretical approach, or combine various theoretical concepts to create a framework for your research.

Like any other academic text , your literature review should have an introduction , a main body, and a conclusion . What you include in each depends on the objective of your literature review.

The introduction should clearly establish the focus and purpose of the literature review.

Depending on the length of your literature review, you might want to divide the body into subsections. You can use a subheading for each theme, time period, or methodological approach.

As you write, you can follow these tips:

Summarize and synthesize: give an overview of the main points of each source and combine them into a coherent whole
Analyze and interpret: don’t just paraphrase other researchers — add your own interpretations where possible, discussing the significance of findings in relation to the literature as a whole
Critically evaluate: mention the strengths and weaknesses of your sources
Write in well-structured paragraphs: use transition words and topic sentences to draw connections, comparisons and contrasts

In the conclusion, you should summarize the key findings you have taken from the literature and emphasize their significance.

A literature review is a survey of scholarly sources (such as books, journal articles, and theses) related to a specific topic or research question .

It is often written as part of a thesis, dissertation , or research paper , in order to situate your work in relation to existing knowledge.

There are several reasons to conduct a literature review at the beginning of a research project:

To familiarize yourself with the current state of knowledge on your topic
To ensure that you’re not just repeating what others have already done
To identify gaps in knowledge and unresolved problems that your research can address
To develop your theoretical framework and methodology
To provide an overview of the key findings and debates on the topic

Writing the literature review shows your reader how your work relates to existing research and what new insights it will contribute.

The literature review usually comes near the beginning of your thesis or dissertation . After the introduction , it grounds your research in a scholarly field and leads directly to your theoretical framework or methodology .

A literature review is a survey of credible sources on a topic, often used in dissertations , theses, and research papers . Literature reviews give an overview of knowledge on a subject, helping you identify relevant theories and methods, as well as gaps in existing research. Literature reviews are set up similarly to other academic texts , with an introduction , a main body, and a conclusion .

An annotated bibliography is a list of source references that has a short description (called an annotation ) for each of the sources. It is often assigned as part of the research process for a paper .

Before you begin searching for literature, you need a clearly defined topic .

If you are writing the literature review section of a dissertation or research paper, you will search for literature related to your research objectives and questions .

If you are writing a literature review as a stand-alone assignment, you will have to choose a focus and develop a central question to direct your search. Unlike a dissertation research question, this question has to be answerable without collecting original data. You should be able to answer it based only on a review of existing publications.

Make a list of keywords

Start by creating a list of keywords related to your research topic. Include each of the key concepts or variables you’re interested in, and list any synonyms and related terms. You can add to this list if you discover new keywords in the process of your literature search.

Social media, Facebook, Instagram, Twitter, Snapchat, TikTok
Body image, self-perception, self-esteem, mental health

You can use boolean operators to help narrow down your search:

Read the abstract to find out whether an article is relevant to your question. When you find a useful book or article, you can check the bibliography to find other relevant sources.

To identify the most important publications on your topic, take note of recurring citations. If the same authors, books or articles keep appearing in your reading, make sure to seek them out.

You probably won’t be able to read absolutely everything that has been written on the topic – you’ll have to evaluate which sources are most relevant to your questions.

For each publication, ask yourself:

What question or problem is the author addressing?
What are the key concepts and how are they defined?
What are the key theories, models and methods? Does the research use established frameworks or take an innovative approach?
What are the results and conclusions of the study?
How does the publication relate to other literature in the field? Does it confirm, add to, or challenge established knowledge?
How does the publication contribute to your understanding of the topic? What are its key insights and arguments?
What are the strengths and weaknesses of the research?

Make sure the sources you use are credible, and make sure you read any landmark studies and major theories in your field of research.

You can find out how many times an article has been cited on Google Scholar – a high citation count means the article has been influential in the field, and should certainly be included in your literature review.

The scope of your review will depend on your topic and discipline: in the sciences you usually only review recent literature, but in the humanities you might take a long historical perspective (for example, to trace how a concept has changed in meaning over time).

Remember that you can use our template to summarise and evaluate sources you’re thinking about using!

How to write a literature review in 6 steps

What is a literature review?

How to write a literature review, 1. determine the purpose of your literature review, 2. do an extensive search, 3. evaluate and select literature, 4. analyze the literature, 5. plan the structure of your literature review, 6. write your literature review, other resources to help you write a successful literature review, frequently asked questions about writing a literature review, related articles.

A literature review is an assessment of the sources in a chosen topic of research.

A good literature review does not just summarize sources. It analyzes the state of the field on a given topic and creates a scholarly foundation for you to make your own intervention. It demonstrates to your readers how your research fits within a larger field of study.

In a thesis, a literature review is part of the introduction, but it can also be a separate section. In research papers, a literature review may have its own section or it may be integrated into the introduction, depending on the field.

➡️ Our guide on what is a literature review covers additional basics about literature reviews.

Identify the main purpose of the literature review.
Do extensive research.
Evaluate and select relevant sources.
Analyze the sources.
Plan a structure.
Write the review.

In this section, we review each step of the process of creating a literature review.

In the first step, make sure you know specifically what the assignment is and what form your literature review should take. Read your assignment carefully and seek clarification from your professor or instructor if needed. You should be able to answer the following questions:

How many sources do I need to include?
What types of sources should I review?
Should I evaluate the sources?
Should I summarize, synthesize or critique sources?
Do I need to provide any definitions or background information?

In addition to that, be aware that the narrower your topic, the easier it will be to limit the number of sources you need to read in order to get a good overview of the topic.

Now you need to find out what has been written on the topic and search for literature related to your research topic. Make sure to select appropriate source material, which means using academic or scholarly sources , including books, reports, journal articles , government documents and web resources.

➡️ If you’re unsure about how to tell if a source is scholarly, take a look at our guide on how to identify a scholarly source .

Come up with a list of relevant keywords and then start your search with your institution's library catalog, and extend it to other useful databases and academic search engines like:

Google Scholar
Science.gov

➡️ Our guide on how to collect data for your thesis might be helpful at this stage of your research as well as the top list of academic search engines .

Once you find a useful article, check out the reference list. It should provide you with even more relevant sources. Also, keep a note of the:

authors' names
page numbers

Keeping track of the bibliographic information for each source will save you time when you’re ready to create citations. You could also use a reference manager like Paperpile to automatically save, manage, and cite your references.

Read the literature. You will most likely not be able to read absolutely everything that is out there on the topic. Therefore, read the abstract first to determine whether the rest of the source is worth your time. If the source is relevant for your topic:

Read it critically.
Look for the main arguments.
Take notes as you read.
Organize your notes using a table, mind map, or other technique.

Now you are ready to analyze the literature you have gathered. While your are working on your analysis, you should ask the following questions:

What are the key terms, concepts and problems addressed by the author?
How is this source relevant for my specific topic?
How is the article structured? What are the major trends and findings?
What are the conclusions of the study?
How are the results presented? Is the source credible?
When comparing different sources, how do they relate to each other? What are the similarities, what are the differences?
Does the study help me understand the topic better?
Are there any gaps in the research that need to be filled? How can I further my research as a result of the review?

Tip: Decide on the structure of your literature review before you start writing.

There are various ways to organize your literature review:

Chronological method : Writing in the chronological method means you are presenting the materials according to when they were published. Follow this approach only if a clear path of research can be identified.
Thematic review : A thematic review of literature is organized around a topic or issue, rather than the progression of time.
Publication-based : You can order your sources by publication, if the way you present the order of your sources demonstrates a more important trend. This is the case when a progression revealed from study to study and the practices of researchers have changed and adapted due to the new revelations.
Methodological approach : A methodological approach focuses on the methods used by the researcher. If you have used sources from different disciplines that use a variety of research methods, you might want to compare the results in light of the different methods and discuss how the topic has been approached from different sides.

Regardless of the structure you chose, a review should always include the following three sections:

An introduction, which should give the reader an outline of why you are writing the review and explain the relevance of the topic.
A body, which divides your literature review into different sections. Write in well-structured paragraphs, use transitions and topic sentences and critically analyze each source for how it contributes to the themes you are researching.
A conclusion , which summarizes the key findings, the main agreements and disagreements in the literature, your overall perspective, and any gaps or areas for further research.

➡️ How to write a literature review in 3 steps

➡️ How to write a literature review in 30 minutes or less

The goal of a literature review is to asses the state of the field on a given topic in preparation for making an intervention.

A literature review should have its own independent section. You should indicate clearly in the table of contents where it can be found, and address this section as “Literature Review.”

There is no set amount of words for a literature review; the length depends on the research. If you are working with a large amount of sources, then it will be long. If your paper does not depend entirely on references, then it will be short.

Most research papers include a literature review. By assessing the available sources in your field of research, you will be able to make a more confident argument about the topic.

Literature reviews are most commonly found in theses and dissertations. However, you find them in research papers as well.

Newcastle University
Academic Skills Kit
Dissertations & Theses

There is no single, conventional way to structure a literature review. However, there are a range of standard approaches that you can choose from to give your literature review an overall shape. The structure you select will depend on the aims and purpose of your literature review as well as the literature that exists.

The function of your literature review

Every literature review needs to show how the research problem you’re investigating arose, and give a critical overview of how it, or aspects of it, have been addressed by other researchers to date. However, within that overall purpose, the particular function of your literature review may vary, depending on your own research aim, the current state of knowledge in the field, and the amount and breadth of literature that currently exists. For example:

If there is a large, longstanding body of research already in your field, the function of your might be to give an overview of how it evolved, to show how you build on it and sit within it.
If there is very little research on your topic or it’s cutting edge, the function of your literature review might be to look at why it’s been overlooked til now, and piece together a useful basis out of comparable work in related fields.
If your research is interdisciplinary, drawing on and bringing together different strands of the literature in new ways, the function of your literature review might be to identify and connect these previously unrelated strands.
If your own research takes a clear stance on a contested topic, the function of your literature review might be to outline why the issue is problematic and the different sides of a debate
If there are various ways you might approach your research or your approach is new, then an overview of the different ways other people have addressed similar research problems might help justify your method.

General approaches

There are four general approaches to structuring a literature review, depending on the main relationship you are creating between the texts you are reviewing, and how they serve your research aims.

This approach is useful if your central aim is to:

Chart the developments in your chosen field in a way that highlights causality and consequence (for instance, how one piece of research informed or gave rise to another and so on)
Use a chronological sequence to demonstrate how an issue or research area has evolved over time

Sometimes, your literature review might aim to bring together previously unrelated areas of research, and there is no linear structure to that relationship – you simply identify the different themes under which you want to organise it, depending on which texts you want to talk about as a group. You might choose to arrange your review into different themes, contexts, schools of thought, subject disciplines, or by methods, theories and approaches.

The funnel structure moves from the broad to the detailed, the general to the specific, or from the abstract to the concrete. So you start with the broader aspects of your topic (the contextual background, for instance) and then gradually narrow your focus until you reach the specific aspect of the topic that you will be addressing. You might equally be looking at the more abstract, theoretical work on your subject before moving to more concrete case studies in which those approaches have been applied, or more general treatments to more detailed and smaller scale studies. That way, you are guiding your reader and helping them build their understanding of your topic: providing them with the background information and context they need in order to grasp your main ideas.

Often, your literature review has more than one function and there is more than one key point you want to convey. For instance, you may need to define your theoretical framework, evaluate how other researchers have approached your topic more generally, then outline your specific area of focus and how it relates to the existing literature. Your finished literature review will then comprise different sub-sections that each achieve a particular aim.

Deciding on a structure

When deciding on a structure, you might find it useful to consider the following questions:

What is the function of my literature review?
What do I want my literature review to demonstrate to the reader? What do I want them to take away from it?
What structure would best allow me to achieve my purpose and get my key points across, talking about the texts I want to bring together without circling around in my writing?

Whichever of these strucutural principles you decide on as a way to organise the whole literature review, you may well be using others of them as a way to structure subsections or even paragraphs. For example, you might be using a thematic approach overall, but each section could be structured chronologically.

Checking in

Each structural approach or option has its own strengths and weaknesses. It’s important to check in with yourself and review your literature review drafts periodically to see if your structure is working for you. Is it helping you convey your main ideas, bring together the texts you want to talk about together, or is it leading you to be descriptive, repetitive or lose sight of the literature’s relevance to your own research? If not, is there another option that might work better for you? Sometimes, our main ideas and key points don’t become clear to us until we start writing. So it may be that you are better placed to make a more informed idea about your structure once you have begun trying it out.

How to Write a Dissertation Literature Review – Steps & Tips

Published by Anastasia Lois at August 12th, 2021 , Revised On October 17, 2023

From an academic standpoint, a dissertation literature review can be defined as a survey of the thesis, journal articles, books, and other academic resources on any given research title . This article provides comprehensive guidelines on how to write a dissertation literature review.

A literature review in a dissertation is of critical importance primarily because it provides insight into the key concepts, advancements, theories, and results of your research questions or research problem .

However, it is essential to note that; a first-class dissertation literature review focuses on summarizing the academic sources used for research and analysing, interpreting, and assessing them to determine the gaps and differences in opinions, judgments, themes, and developments.

A good literature review will further elaborate on existing knowledge concerning the research hypothesis or questions.

When do you Write a Dissertation Literature Review?

Depending on your university’s guidelines, you might be required to include a literature review in the theoretical framework or the introduction.

Or you could also be asked to develop a standalone literature review chapter that appears before the methodology and the findings chapters of the dissertation.

In either case, your primary aim will be to review the available literature and develop a link between your research and the existing literature on your chosen topic.

Sometimes, you might be designated a literature review as a separate assignment . Regardless of whether you need to write a literature review for your dissertation or as a standalone project, some general guidelines for conducting literature will remain unchanged.

Here are the steps you need to take to write the literature review for a dissertation if you cannot write the literature review.

Steps of Writing a Literature Review

1. gather, assess, and choose relevant literature.

The first seed to take when writing your dissertation or thesis is to choose a fascinating and manageable research topic . Once a topic has been selected, you can begin searching for relevant academic sources.

If you are writing a literature review for your dissertation, one way to do this is to find academic sources relevant to your research problem or questions.

Without fully understanding current knowledge in the chosen study area, giving the correct direction to your research aim and objectives will be hard.

On the other hand, you will be expected to guide your research by developing a central question if you are writing a literature review as an individual assignment.

A notable difference here compared to the dissertation literature review is that you must answer this central question without conducting primary research (questionnaires, surveys, interviews). You will be expected to address the question using only the existing literature.

Use Keywords and References to Find Relevant Literature

Create a list of keywords that are relevant to the topic of research. Find journals, articles, and books using these keywords. Here are links to some recognised online academic libraries and databases;

Inspec, (Computer science, engineering, physics, chemistry)
EconLit, (Economics)
Google Scholar
Your university’s online research database

Finding relevant academic sources from “the reference list” of an article you have already found in a research database effectively discovers relevant studies.

Consider noting frequently appearing references as they are likely to be highly authentic and important publications even though they didn’t appear in the keyword search.

Journal articles or books that keep appearing with different keywords and phrases are the ones you should manually look out for.

The more times an article has been referenced, the more influential it is likely to be in any research field. Google Scholar lets users quickly determine how often a particular article has been referenced.

2. Weighing and Selecting Academic Sources

It won’t be possible for you to read every publication related to your topic. An excellent way to select academic sources for your dissertation literature review is to read the abstract , which will help you decide whether the source is supportive and relevant to your research hypothesis or research questions.

To help you select sources relevant to your study, here are some questions for you to consider before making the decision.

What research questions has the author answered with their research work?
What fundamental concepts have been defined by the author?
Did the researcher use an innovative methodology or existing frameworks to define fundamental methods, models, and theories?
What are the findings, conclusion, and recommendations in the source book or paper?
What is the relevance between the existing literature and the academic sources you are evaluating?
Does the source article challenge, confirm, or add to existing knowledge on the topic?
How does the publication contribute to your understanding of the topic? What are its key insights and arguments?
What are the strengths and weaknesses of the research?

Any breakthrough studies and key theories relevant to your research topic should be recorded as you search for highly credible and authentic academic sources.

The method of your review of literature depends on your academic subject. If your research topic is in the sciences, you must find and review up-to-date academic sources.

On the other hand, you might look into old and historical literature and recent literature if your research topic is in the humanities field.

Recording Information and Referencing Sources

It is recommended that you start to write your literature review as you read articles, journals, and books. Take notes which can be later merged into the text of the literature review. Avoid plagiarism and record all sources used along with references.

A good way of recording information is to analyse each source, summarise the key concepts or theories and compile a complete list of references in the form of an annotated bibliography.

This is a beneficial practice as it helps to remember the key points in each academic source and saves you valuable time as you start the literature review write-up.

3. Identify Key Themes and Patterns

The next step is to look for themes and patterns in the chosen sources that would enable you to establish similarities and differences between their results and interpretations .

This exercise will help you to determine the structure and argument for your literature review. Here are some questions that you can think of when reading and recording information;

Are any gaps in the existing literature?
What are the weaknesses of the current literature that should be addressed?
Were you able to identify any landmark research work and theories that resulted in the topic’s change of direction?
What are the similarities and disagreements between these sources? Were you able to identify any contradictions and conflicts?
What trends and themes were you able to identify? Are there any results, methods, or theories that lost credibility over time?

4. Structure of Literature Review

There is no acclaimed literature review structure , which means that you can choose from a range of approaches (thematic, chronological, methodological, and theoretical) when deciding on the structure of the literature review .

However, before you begin to write the literature review , it is important to figure out the strategy that would work best for you. For long literature reviews, you might decide to use a combination of these strategies. For example, you could discuss each of the themes chronologically.

1: Theoretical

You can discuss various significant concepts, models, and theories in your literature review to form the basis of a theoretical framework . You could also combine a range of theoretical approaches to develop your theoretical framework or debate the significance of a particular theoretical framework.

2: Methodological

The methodological approach will require you to relate the findings of studies conducted in different research areas and use different research methods .

You might discover that results from the quantitative research approach are not the same as qualitative research.
You might split the selected academic sources based on their discipline – engineering, and sciences.

3: Thematic

You may also deploy a thematic approach, especially if you identified repeating key themes and patterns. If that is the case, you will be expected to put each aspect of the topic into different subsections within your literature review.

For example, if your research topic is “employment issues in the UK for international students,” you can divide the key themes into subsections; legal status, poor language skills, immigration policy, and economic turmoil.

4: Chronological

The most straightforward approach is to trace the development of the topic over time. However, if you choose this strategy, avoid simply listing and summarizing sources in order.

Try to analyze patterns, turning points, and critical debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred.

5. Writing your Literature Review

Whether it’s a dissertation literature review or a standalone literature review assignment you have been assigned, you will be expected to divide your literature review into three larger sections – introduction, main body, and a conclusion.

What you write under these three segments will depend on the aim of your study.

Section 1 – Introduction

Here you will be required to state the objectives of the literature review clearly;

Introduction to Dissertation Literature Review Recapitulate your research problem or questions with a summary of the sources you reviewed when the literature review is for your thesis or dissertation. Consider highlighting gaps in existing knowledge and stress the suitability of your topic.

For example:

Research problem A has been debated in many recent studies.

While the topic has been explored concerning A, the B aspect has not yet been explored.

Individual Literature Review Project When reviewing literature for an individual literature review assignment, make sure that you clearly state the purpose of the research and debate the scope of the literature (how recent or old are the academic sources you are reviewing).

Section 2 – Main Body

As previously mentioned, you can divide this section into further subsections depending on your literature review’s length. You can also have a separate heading for each research method, theme, or theory to help your readers better understand your research.

Here are some tips for you to write a flawless main body of literature review;

Summarize and Combine ; Highlight the main findings from each academic source and organise them into one whole piece without losing coherence.
Evaluate and interpret; Make sure you are giving opinions and arguments of your own where possible. Simply rephrasing what others have said will undermine your work. You will be expected to debate and discuss other studies’ results about your research questions or aim.
Analytical Evaluation; It is essential to unmistakably present the literature you have reviewed and the merits and weaknesses of the literature.
Make Use of Topic Sentences and Transitions; in organized subsections within the literature review to establish conflicts, differences, similarities, and relationships.

Example of How to Write a Dissertation Literature Review

The below example belongs to the body of a literature review on the effectiveness of e-recruitment in small and medium-sized enterprises in the United Kingdom’s IT sector.

E-recruitment means explicitly using digital technologies to recruit, select, and orient employees. The benefits of e-recruitment in the literature have been studied: increased access to a pool of candidates, time and cost savings, and greater flexibility for the organisation.

In contrast, the literature states that e-recruitment might not properly achieve the goal of retaining the workforce with the required skills to participate in the work environment (Lad & Das, 2016). Also, e-recruitment might be based on a flawed website design or poor application process, which might deter potential employees (Anand & Devi, 2016) .

This section of the study will focus on the existing studies linked to the effectiveness of e-recruitment. Human resource management is an essential function of business organisations because it manages the workforce.

The goal of HR should be to develop a strategic approach in which the organisation’s strategic goals can be attained efficiently and effectively. The advent of digital technologies has helped transform human resource management’s nature concerning recruiting and selecting employees for organisations.

The Internet’s benefits have reduced search time for candidates and significant cost savings for organisations. Finally, it offers a transparent method for obtaining information about specific candidates. E-recruitment helps organisations hire people from any part of the world as it promotes opportunities and benefits the organisation efficiently.

Sharma (2014) argues that 75% of human resource professionals in developed countries are now using e-recruitment to hire employees for their organisations. Additionally, some 2 out of 4 job seekers will use the Internet to source job opportunities.

Another evidence to support the rise of e-recruitment is a study by Holm (2014), which found that all Fortune 100 companies will be using some form of e-recruitment to advertise vacant positions.

The implications are that e-recruitment is a popular strategy for various positions, from blue-collar roles to white-collar and professional positions. The benefits of e-recruitment have been identified in the literature. Girard & Fallery (2009) argues that e-recruitment helps to save time for organisations and employees.

Employers can use several methods to post jobs in as little as 20 minutes. There are no limits to ad size, and they can receive resumes immediately. In contrast, the traditional methods require some time to appear, for example, in a newspaper, and might be there for a limited period.

Section 3 – Conclusion

When writing the dissertation literature review conclusion, you should always include a summary of the key findings which emerged from the literature and their relevance and significance to your research objectives.

Literature Review for Dissertation

If you are writing a dissertation literature review, you will be required to demonstrate how your research helped to fill an evident gap in research and contributed to the current knowledge in the field. Similarly, you can explain how you used the existing patterns, themes, and theories to develop your research framework.

Literature Review as an Individual Assignment

You can summarize your review of your literature’s significance and implications and provide recommendations for future work based on the gaps in existing knowledge you acknowledged.

6. Proofread

Finally, thoroughly proofread your literature review for grammatical, structural, spelling, and factual errors before submitting it to your university.

If you are unable to proofread and edit your paper, then you could take advantage of our editing and proofreading service , which is designed to ensure that your completed literature review satisfies each of your module or project’s requirements. We have Masters and PhD qualified writers in all academic subjects, so you can be confident that they will edit and improve the quality of your to 2:1 or First Class standard, as required.

Valuable Tips for Writing Dissertation Literature Review

Your literature review must systematically comply with your research area. Underneath, we are stating some essential guidelines for a compact literature review.

Contribute to the Literature

After carefully reviewing the literature, search for the gaps in knowledge and state how you have analysed the literature with a different perspective and contributed to your research area.

Keep your Argument Systematic & Consistent

Your arguments must be consistent and systematic while discussing theories and controversial and debatable content. Be logical in your review and avoid vague statements, not to make it complex for the readers.

Provide Adequate References

Don’t forget to provide references, as they are the soul of the dissertation. While discussing different aspects of the research, provide a reasonable number of references, as your discussion and interpretations must be backed up by relevant evidence. You can see an example provided in the sample paragraph above.

Be Precise While Writing a Review

You aren’t required to write every inch of information you have studied while reviewing the literature. You will be able to find tons of information that will correlate with your research area.

Be precise while writing the review, as writing unnecessary, irrelevant information won’t give a good impression. State the most reliable sources in your review without jumping into every possible source.

Don’t go Excessively for Direct Quotes

Direct quoting is required to make a point more impactful, but you should opt for it to a specific limit. Making excessive use of it won’t be a good idea.

The direct quote is mainly used when you think that the words being used by the actual author are so authentic in their meaning that you can’t replace or rephrase them. Try to avoid relying too much on a single author/s work.

Discussing their contributions and keeping the review going briefly would be better. While mentioning the points discussed by the prior researchers – link your arguments with their discussion. Don’t write the crux of their discussion, yet tell if your argument goes along with them.

Express your Analysis

The literature review is written to summarize your perspective, which should be backed up in light of the literature. Critically analyze literature with a rational approach and express your opinion on it.

Use the Correct Referencing Style

While referencing, one must use proper referencing styles, i.e., Harvard reference style, etc. Different referencing styles are used for in-text citations, while different for end-text citations.

Overview of writing the literature review

Conducting a literature review enables you to demonstrate your understanding and knowledge of the existing work within your field of research. Doing so allows you to identify any underdeveloped areas or unexplored issues within a specific debate, dialogue or field of study. This, in turn, helps you to clearly and persuasively demonstrate how your own research will address one or more of these gaps.

Disciplinary differences

Please note: this guide is not specific to any one discipline. The literature review can vary depending on the nature of the research and the expectations of the school or department. Please adapt the following advice to meet the demands of your dissertation and the expectations of your school or department. Consult your supervisor for further guidance; you can also check out Writing Across Subjects guide .

What is the literature review?

The literature review of a dissertation gives a clear, critical overview of a specific area of research. Our main Writing the Dissertation - Overview and Planning guide explains how you can refine your dissertation topic and begin your initial research; the next tab of this guide, 'Process', expands on those ideas. In summary, the process of conducting a literature review usually involves the following:

Conducting a series of strategic searches to identify the key texts within that topic.
Identifying the main argument in each source, the relevant themes and issues presented and how they relate to each other.
Critically evaluating your chosen sources and determining their strengths, weaknesses, relevance and value to your research along with their overall contribution to the broader research field.
Identifying any gaps or flaws in the literature which your research can address.

Literature review as both process and product

Writers should keep in mind that the phrase 'literature review' refers to two related, but distinct, things:

'Literature review' refers, first, to the active process of discovering and assessing relevant literature.
'Literature review' refers, second, to the written product that emerges from the above process.

This distinction is vital to note because every dissertation requires the writer to engage with and consider existing literature (i.e., to undertake the active process ). Research doesn't exist in a void, and it's crucial to consider how our work builds from or develops existing foundations of thought or discovery. Thus, even if your discipline doesn't require you to include a chapter titled 'Literature Review' in your submitted dissertation, you should expect to engage with the process of reviewing literature.

Why is it important to be aware of existing literature?

You are expected to explain how your research fits in with other research in your field and, perhaps, within the wider academic community.
You will be expected to contribute something new, or slightly different, so you need to know what has already been done.
Assessing the existing literature on your topic helps you to identify any gaps or flaws within the research field. This, in turn, helps to stimulate new ideas, such as addressing any gaps in knowledge, or reinforcing an existing theory or argument through new and focused research.

Not all literature reviews are the same. For example, in many subject areas, you are expected to include the literature review as its own chapter in your dissertation. However, in other subjects, the dissertation structure doesn't include a dedicated literature review chapter; any literature the writer has reviewed is instead incorporated in other relevant sections such as the introduction, methodology or discussion.

For this reason, there are a number of questions you should discuss with your supervisor before starting your literature review. These questions are also great to discuss with peers in your degree programme. These are outlined in the table below (see the Word document for a copy you can save and edit):

Literature review: the process

Conducting a literature review requires you to stay organised and bring a systematic approach to your thinking and reading. Scroll to continue reading, or click a link below to jump immediately to that section:

Choosing a topic

The first step of any research project is to select an interesting topic. From here, the research phase for your literature review helps to narrow down your focus to a particular strand of research and to a specific research question. This process of narrowing and refining your research topic is particularly important because it helps you to maintain your focus and manage your material without becoming overwhelmed by sources and ideas.

Try to choose something that hasn’t been researched to death. This way, you stand a better chance of making a novel contribution to the research field.

Conversely, you should avoid undertaking an area of research where little to no work has been done. There are two reasons for this:

Firstly, there may be a good reason for the lack of research on a topic (e.g. is the research useful or worthwhile pursuing?).
Secondly, some research projects, particularly practice-based ones involving primary research, can be too ambitious in terms of their scope and the availability of resources. Aim to contribute to a topic, not invent one!

Searching for sources

Researching and writing a literature review is partly about demonstrating your independent research skills. Your supervisor may have some tips relating to your discipline and research topic, but you should be proactive in finding a range of relevant sources. There are various ways of tracking down the literature relevant to your project, as outlined below.

Make use of Library Search

One thing you don’t want to do is simply type your topic into Google and see what comes up. Instead, use Library Search to search the Library’s catalogue of books, media and articles.

Online training for 'Using databases' and 'Finding information' can be found here . You can also use the Library's subject pages to discover databases and resources specific to your academic discipline.

Engage with others working in your area

As well as making use of library resources, it can be helpful to discuss your work with students or academics working in similar areas. Think about attending relevant conferences and/or workshops which can help to stimulate ideas and allows you to keep track of the most current trends in your research field.

Look at the literature your sources reference

Finding relevant literature can, at times, be a long and slightly frustrating experience. However, one good source can often make all the difference. When you find a good source that is both relevant and valuable to your research, look at the material it cites throughout and follow up any sources that are useful. Also check if your source has been cited in any more recent publications.

Cartoon person with magnifying glass follows footstep patterns. Text reads 'Found a great source? Follow the trail!'

Think of the bibliography/references page of a good source as a series of breadcrumbs that you can follow to find even more great material.

Evaluating sources

It is very important to be selective when choosing the final sources to include in your literature review. Below are some of the key questions to ask yourself:

If a source is tangentially interesting but hasn’t made any particular contribution to your topic, it probably shouldn’t be included in your literature review. You need to be able to demonstrate how it fits in with the other sources under consideration, and how it has helped shape the current state of the literature.
There might be a wealth of material available on your chosen subject, but you need to make sure that the sources you use are appropriate for your assignment. The safest approach to take is to use only academic work from respected publishers. However, on occasions, you might need to deviate from traditional academic literature in order to find the information you need. In many cases, the problem is not so much the sources you use, but how you use them. Where relevant, information from newspapers, websites and even blogs are often acceptable, but you should be careful how you use that information. Do not necessarily take any information as factual. Instead be critical and interpret the material in the context of your research. Consider who the writer is and how this might influence the authority and reliability of the information presented. Consult your supervisor for more specific guidance relating to your research.
The mere fact that something has been published does not automatically guarantee its quality, even if it comes from a reputable publisher. You will need to critique the content of the source. Has the author been thorough and consistent in their methodology? Do they present their thesis coherently? Most importantly, have they made a genuine contribution to the topic?

Keeping track of your sources

Once you have selected a source to use in your literature review, it is useful to make notes on all of its key features, including where it comes from, what it says, and what its main strengths and weaknesses are. This way you can easily re-familiarise yourself with a source without having to re-read it. Keeping an annotated bibliography is one way to do this.

Alternately, below is a table you can copy and fill out for each source (see the Word document to save an editable copy for yourself). Software such as EndNote also allows you to keep an electronic record of references and your comments on them.

Source evaluation table

Writing your literature review

As we explored in the 'Getting Started' tab, the literature review is both a process you follow and (in most cases) a written chapter you produce. Thus, having engaged the review process, you now need to do the writing itself. Please continue reading, or click a heading below to jump immediately to that section.

Guiding principles

The structure of the final piece will depend on the discipline within which you are working as well as the nature of your particular research project. However, here are a few general pieces of advice for writing a successful literature review:

Show the connections between your sources. Remember that your review should be more than merely a list of sources with brief descriptions under each one. You are constructing a narrative. Show clearly how each text has contributed to the current state of the literature, drawing connections between them.
Engage critically with your sources. This means not simply describing what they say. You should be evaluating their content: do they make sound arguments? Are there any flaws in the methodology? Are there any relevant themes or issues they have failed to address? You can also compare their relative strengths and weaknesses.
Signpost throughout to ensure your reader can follow your narrative. Keep relating the discussion back to your specific research topic.
Make a clear argument. Keep in mind that this is a chance to present your take on a topic. Your literature review showcases your own informed interpretation of a specific area of research. If you have followed the advice given in this guide you will have been careful and selective in choosing your sources. You are in control of how you present them to your reader.

There are several different ways to structure the literature review chapter of your dissertation. Two of the most common strategies are thematic structure and chronological structure (the two of which can also be combined ). However you structure the literature review, this section of the dissertation normally culminates in identifying the research gap.

Thematic structure

Variations of this structure are followed in most literature reviews. In a thematic structure , you organise the literature into groupings by theme (i.e., subtopic or focus). You then arrange the groupings in the most logical order, starting with the broadest (or most general) and moving to the narrowest (or most specific).

The funnel or inverted pyramid

To plan a thematic structure structure, it helps to imagine your themes moving down a funnel or inverted pyramid from broad to narrow. Consider the example depicted below, which responds to this research question:

What role did the iron rivets play in the sinking of the Titanic?

The topic of maritime disasters is the broadest theme, so it sits at the broad top of the funnel. The writer can establish some context about maritime disasters, generally, before narrowing to the Titanic, specifically. Next, the writer can narrow the discussion of the Titanic to the ship's structural integrity, specifically. Finally, the writer can narrow the discussion of structural integrity to the iron rivets, specifically. And voila: there's the research gap!

Funnel divided into layers. Layer 1: Research on maritime disasters. Layer 2: Research on the Titanic. Layer 3: Research on structural integrity of Titanic. Layer 4: Role of iron rivets in Titanic sinking. Layer 5: My research.

The broad-to-narrow structure is intuitive for readers. Thus, it is crucial to consider how your themes 'nest inside' one another, from the broad to the narrow. Picturing your themes as nesting dolls is another way to envision this literature review structure, as you can see in the image below.

Five nesting dolls labelled left to right: 1.1 Maritime disasters; 1.2 The Titanic; 1.3 Structural integrity; 1.4 Iron rivets; and 1.5 Research gap.

As with the funnel, remember that the first layer (or in this case, doll) is largest because it represents the broadest theme. In terms of word count and depth, the tinier dolls will warrant more attention because they are most closely related to the research gap or question(s).

The multi-funnel variation

The example above demonstrates a research project for which one major heading might suffice, in terms of outlining the literature review. However, the themes you identify for your dissertation might not relate to one another in such a linear fashion. If this is the case, you can adapt the funnel approach to match the number of major subheadings you will need.

In the three slides below, for example, a structure is depicted for a project that investigates this (fictional) dissertation research question: does gender influence the efficacy of teacher-led vs. family-led learning interventions for children with ADHD? Rather than nesting all the subtopics or themes in a direct line, the themes fall into three major headings.

The first major heading explores ADHD from clinical and diagnostic perspectives, narrowing ultimately to gender:

1.1 ADHD intro
1.2 ADHD definitions
1.3 ADHD diagnostic criteria
1.4 ADHD gender differences

The second major heading explores ADHD within the classroom environment, narrowing to intervention types:

2.1 ADHD in educational contexts
2.2 Learning interventions for ADHD
2.2.1 Teacher-led interventions
2.2.2 Family-led interventions

The final major heading articulates the research gap (gender differences in efficacy of teacher-led vs. family-led interventions for ADHD) by connecting the narrowest themes of the prior two sections.

Multi-funnel literature review structure by Academic Skills Service

To create a solid thematic structure in a literature review, the key is thinking carefully and critically about your groupings of literature and how they relate to one another. In some cases, your themes will fit in a single funnel. In other cases, it will make sense to group your broad-to-narrow themes under several major headings, and then arrange those major headings in the most logical order.

Chronological structure

Some literature reviews will follow a chronological structure . As the name suggests, a review structured chronologically will arrange sources according to their publication dates, from earliest to most recent.

This approach can work well when your priority is to demonstrate how the research field has evolved over time. For example, a chronological arrangement of articles about artificial intelligence (AI) would allow the writer to highlight how breakthroughs in AI have built upon one another in sequential order.

A chronological structure can also suit literature reviews that need to capture how perceptions or understandings have developed across a period of time (including to the present day). For example, if your dissertation involves the public perception of marijuana in the UK, it could make sense to arrange that discussion chronologically to demonstrate key turning points and changes of majority thought.

The chronological structure can work well in some situations, such as those described above. That being said, a purely chronological structure should be considered with caution. Organising sources according to date alone runs the risk of creating a fragmented reading experience. It can be more difficult in a chronological structure to properly synthesize the literature. For these reasons, the chronological approach is often blended into a thematic structure, as you will read more about, below.

Combined structures

The structures of literature reviews can vary drastically, and for any given dissertation there will be many valid ways to arrange the literature.

For example, many literature reviews will combine the thematic and chronological approaches in different ways. A writer might match their major headings to themes or subtopics, but then arrange literature chronologically within the major themes identified. Another writer might base their major headings on chronology, but then assign thematic subheadings to each of those major headings.

When considering your options, try to imagine your reader or audience. What 'flow' will allow them to best follow the discussion you are crafting? When you are reading articles, what structural approaches do you appreciate in terms of ease and clarity?

Identifying the gap

The bulk of your literature review will explore relevant points of development and scholarly thought in your research field: in other words, 'Here is what has been done so far, thus here is where the conversation now stands'. In that way, you position your project within a wider academic discussion.

Having established that context, the literature review generally culminates in an articulation of what remains to be done: the research gap your project addresses. See the next tab for further explanation and examples.

Demystifying the research gap

The term research gap is intimidating for many students, who might mistakenly believe that every single element of their research needs to be brand new and fully innovative. This isn't the case!

The gap in many projects will be rather niche or specific. You might be helping to update or re-test knowledge rather than starting from scratch. Perhaps you have repeated a study but changed one variable. Maybe you are considering a much discussed research question, but with a lesser used methodological approach.

To demonstrate the wide variety of gaps a project could address, consider the examples below. The categories used and examples included are by no means comprehensive, but they should be helpful if you are struggling to articulate the gap your literature review has identified.

***P lease note that the content of the example statements has been invented for the sake of demonstration. The example statements should not be taken as expressions of factual information.

Gaps related to population or geography

Many dissertation research questions involve the study of a specific population. Those populations can be defined by nationality, ethnicity, gender, sexuality, socioeconomic class, political beliefs, religion, health status, or other factors. Other research questions target a specific geography (e.g. a country, territory, city, or similar). Perhaps your broader research question has been pursued by many prior scholars, but few (or no) scholars have studied the question in relation to your focal population or locale: if so, that's a gap.

Example 1: As established above, the correlations between [ socioeconomic status ] and sustainable fashion purchases have been widely researched. However, few studies have investigated the potential relationship between [ sexual identity ] and attitudes toward sustainable fashion. Therefore...
Example 2: Whilst the existing literature has established a clear link between [ political beliefs ] and perceptions of socialized healthcare, the influence of [ religious belief ] is less understood, particularly in regards to [ Religion ABC ].
Example 3: Available evidence confirms that the widespread adoption of Technology XYZ in [ North America ] has improved manufacturing efficiency and reduced costs in the automotive sector. Using predictive AI models, the present research seeks to explore whether deployment of Technology XYZ could benefit the automotive sector of [ Europe ] in similar ways.

Gaps related to theoretical framework

The original contribution might involve examining something through a new lens. Theoretical framework refers, most simply, to the theory or theories a writer will use to make sense of and shape (i.e., frame ) their discussion. Perhaps your topic has been analysed in great detail through certain theoretical lenses, but you intend to frame your analysis using a theory that fewer scholars have applied to the topic: if so, that's a gap.

Example 1: Existing discussions of the ongoing revolution in Country XYZ frame the unrest in terms of [ theory A ] and [ theory B ]. The present research will instead analyse the situation using [ theory C ], allowing greater insight into...
Example 2: In the first section of this literature review, I examined the [ postmodern ], [ Marxist ], and [ pragmatist ] analyses that dominate academic discussion of The World According to Garp. By revisiting this modern classic through the lens of [ queer theory ], I intend to...

Gaps related to methodological approach

The research gap might be defined by differences of methodology (see our Writing the Methodology guide for more). Perhaps your dissertation poses a central question that other scholars have researched, but they have applied different methods to find the answer(s): if so, that's a gap.

Example 1: Previous studies have relied largely upon the [ qualitative analysis of interview transcripts ] to measure the marketing efficacy of body-positive advertising campaigns. It is problematic that little quantitative data underpins present findings in this area. Therefore, I will address this research gap by [ using algorithm XYZ to quantify and analyse social-media interactions ] to determine whether...
Example 2: Via [ quantitative and mixed-methods studies ], previous literature has explored how demographic differences influence the probability of a successful match on Dating App XYZ. By instead [ conducting a content analysis of pre-match text interactions ] on Dating App XYZ, I will...

Scarcity as a gap

Absolutes such as never and always rarely apply in academia, but here is an exception: in academia, a single study or analysis is never enough. Thus, the gap you address needn't be a literal void in the discussion. The gap could instead have to do with replicability or depth/scope. In these cases, you are adding value and contributing to the academic process by testing emerging knowledge or expanding underdeveloped discussions.

Example: Initial research points to the efficacy of Learning Strategy ABC in helping children with dyslexia build their reading confidence. However, as detailed earlier in this review, only four published studies have tested the intervention, and two of those studies were conducted in a laboratory. To expand our growing understanding of how Learning Strategy ABC functions in classroom environments, I will...

Elapsed time as a gap

Academia values up-to-date knowledge and findings, so another valid type of gap relates to elapsed time. Many factors that can influence or shape research findings are ever evolving: technology, popular culture, and political climates, to name just a few. Due to such changes, it's important for scholars in most fields to continually update findings. Perhaps your dissertation adds value by contributing to this process.

For example, imagine if a scholar today were to rely on a handbook of marketing principles published in 1998. As good as that research might have been in 1998, technology (namely, the internet) has advanced drastically since then. The handbook's discussion of online marketing strategies will be laughably outdated when compared to more recent literature.

Example: A wide array of literature has explored the ways in which perceptions of gender influence professional recruitment practices in the UK. The bulk of said literature, however, was published prior to the #MeToo movement and resultant shifts in discourse around gender, power imbalances and professional advancement. Therefore...

What to avoid

This portion of the guide will cover some common missteps you should try to avoid in writing your literature review. Scroll to continue reading, or click a heading below to jump immediately to that section.

Writing up before you have read up

Trying to write your literature review before you have conducted adequate research is a recipe for panic and frustration. The literature review, more than any other chapter in your dissertation, depends upon your critical understanding of a range of relevant literature. If you have only dipped your toe into the pool of literature (rather than diving in!), you will naturally struggle to develop this section of the writing. Focus on developing your relevant bases of knowledge before you commit too much time to drafting.

Believing you need to read everything

As established above, a literature review does require a significant amount of reading. However, you aren't expected to review everything ever written about your topic. Instead, aim to develop a more strategic approach to your research. A strategic approach to research looks different from one project to the next, but here are some questions to help you prioritise:

If your field values up-to-date research and discoveries, carefully consider the 'how' and 'what' before investing time reading older sources: how will the source function in your dissertation, and what will it add to your writing?
Try to break your research question(s) down into component parts. Then, map out where your literature review will need to provide extensive detail and where it can instead present quicker background. Allocate your research time and effort accordingly.

Omitting dissenting views or findings

While reviewing the literature, you might discover authors who disagree with your central argument or whose own findings contradict your hypothesis. Don't omit those sources: embrace them! Remember, the literature review aims to explore the academic dialogue around your topic: disagreements or conflicting findings are often part of that dialogue, and including them in your writing will create a sense of rich, critical engagement. In fact, highlighting any disagreements amongst scholars is a great way to emphasise the relevance of, and need for, your own research.

Miscalculating the scope

As shown in the funnel structure (see 'Structure' tab for more), a literature review often starts broadly and then narrows the dialogue as it progresses, ultimately bringing the reader to the dissertation's specific research topic (e.g. the funnel's narrowest point).

Within that structure, it's common for writers to miscalculate the scope required. They might open the literature review far too broadly, dedicating disproportionate space to developing background information or general theory; alternately, they might rush into the narrowest part of the discussion, failing to develop any sense of surrounding context or background, first.

It takes trial and error to determine the appropriate scope for your literature review. To help with this...

Imagine your literature review subtopics cascading down a stairwell, as in the illustration below.
Place the broadest concepts on the highest steps, then narrow down to the most specific concepts on the lowest steps: the scope 'zooms in' as you move down the stairwell.
Now, consider which step is the most logical starting place for your readers. Do they need to start all the way at the top, or should you 'zoom in'?

Stairwell sloping down with topics written on steps, top to bottom: Feminism; feminist theories; feminist literary theory (FLT); FLT and horror; FLT and Stephen King; FLT and the Stand.

The illustration above shows a stairwell diagram of a dissertation that aims to analyse Stephen King's horror novel The Stand through the lens of a specific feminist literary theory.

If the literature review began on one of the bottom two steps, this would feel rushed and inadequate. The writer needs to explore and define the relevant theoretical lens before they discuss how it has been applied by other scholars.
If the literature review began on the very top step, this would feel comically broad in terms of scope: in this writing context, the reader doesn't require a detailed account of the entire history of feminism!

The third step, therefore, represents a promising starting point: not too narrow, not too broad.

The 'islands' structure

Above all else, a literature review needs to synthesize a range of sources in a logical fashion. In this context, to synthesize means to bring together, connect, weave, and/or relate. A common mistake writers make is failing to conduct such synthesis, and instead discussing each source in isolation. This leads to a disconnected structure, with each source treated like its own little 'island'. The island approach works for very few projects.

Some writers end up with this island structure because they confuse the nature of the literature review with the nature of an annotated bibliography . The latter is a tool you can use to analyse and keep track of individual sources, and most annotated bibliographies will indeed be arranged in a source-by-source structure. That's fine for pre-writing and notetaking, but to structure the literature review, you need to think about connections and overlaps between sources rather than considering them as stand-alone works.

If you are struggling to forge connections between your sources, break down the process into tiny steps:

e.g. Air pollution from wood-burning stoves in homes.
e.g. Bryant and Dao (2022) found that X% of small particle pollution in the United Kingdom can be attributed to the use of wood-burning stoves.
e.g. A study by Williams (2023) reinforced those findings, indicating that small particle pollution has...
e.g. However, Landers (2023) cautions that factor ABC and factor XYZ may contribute equally to poor air quality, suggesting that further research...

The above exercise is not meant to suggest that you can only write one sentence per source: you can write more than that, of course! The exercise is simply designed to help you start synthesizing the literature rather than giving each source the island treatment.

Q: I still don't get it - what's the point of a literature review?

A: Let's boil it down to three key points...

The literature review provides a platform for you, as a scholar, to demonstrate your understanding of how your research area has evolved. By engaging with seminal texts or the most up-to-date findings in your field, you can situate your own research within the relevant academic context(s) or conversation(s).
The literature review allows you to identify the research gap your project addresses: in other words, what you will add to discussions in your academic field.
Finally, the literature review justifies the reason for your research. By exploring existing literature, you can highlight the relevance and purpose of your own research.

Q: What if I don't have a gap?

A: It's normal to struggle with identifying a research gap. This can be particularly true if you are working in a highly saturated research area, broadly speaking: for example, if you are studying the links between nutrition and diabetes, or if you are studying Shakespeare.

Library catalog keyword search for 'diabetes' and 'nutrition', showing about 101,000 results.

The 'What to Avoid' tab explained that miscalculating the scope is a common mistake in literature reviews. If you are struggling to identify your gap, scope might be the culprit, particularly if you are working in a saturated field. Remember that the gap is the narrowest part of the funnel, the smallest nesting doll, the lowest step: this means your contribution in that giant academic conversation will need to be quite 'zoomed in':

This is not a valid gap → Analysing Shakespeare's sonnets.

This might be a valid gap → Conducting an ecocritical analysis of the visual motifs of Shakespeare's final five procreation sonnets (e.g. sonnets number thirteen to seventeen).

In the above example, the revised attempt to articulate a gap 'zooms in' by identifying a particular theoretical lens (e.g. ecocriticism), a specific convention to analyse (e.g. use of visual motifs), and a narrower object (e.g. five sonnets rather than all 150+). The field of Shakespeare studies might be crowded, but there is nonetheless room to make an original contribution.

Conversely, it might be difficult to identify the gap if you are working not in a saturated field, but in a brand new or niche research area. How can you situate your work within a relevant academic conversation if it seems like the 'conversation' is just you talking to yourself?

Library catalog keyword search for 'hippogriffs' and 'anatomy' showing only 2 search results.

In these cases, rather than 'zooming in', you might find it helpful to 'zoom out'. If your topic is niche, think creatively about who will be interested in your results. Who would benefit from understanding your findings? Who could potentially apply them or build upon them? Thinking of this in interdisciplinary terms is helpful for some projects.

Tip: Venn diagrams and mind maps are great ways to explore how your research connects to, and diverges from, the existing literature.

Q: How many references should I use in my literature review?

A: This question is risky to answer because the variations between individual projects and disciplines make it impossible to provide a universal answer. The fact is that one dissertation might have 50 more references than another, yet the two projects could be equally rigorous and successful in fulfilling their research aims.

With that warning in mind, let's consider a 'standard' dissertation of around 10K words. In that context, referencing 30 to 40 sources in your literature review tends to work well. Again, this is not a universally accurate rule, but a ballpark figure for you to contemplate. If the 30 to 40 estimate seems frighteningly high to you, do remember that many sources will be used sparingly rather than being mulled over at length. Consider this example:

In British GP practices, pharmaceutical treatment is most often prescribed for Health Condition XYZ ( Carlos, 2019; Jones, 2020 ; Li, 2022 ). Lifestyle modifications, such as physical exercise or meditation practices, have only recently...

When writing critically, it's important to validate findings across studies rather than trusting only one source. Therefore, this writer has cited three recent studies that agree about the claim being made. The writer will delve into other sources at more length, but here, it makes sense to cite the literature and move quickly along.

As you search the databases and start following the relevant trails of 'research bread crumbs', you will be surprised how quickly your reference list grows.

Q: What if there isn't enough relevant literature on my topic?

A: Think creatively about the literature you are using and engaging with. A good start is panning out to consider your topic more broadly: you might not identify articles that discuss your exact topic, but what can you discover if you shift your focus up one level?

Imagine, for example, that Norah is researching how artificial intelligence (AI) can be used to provide dance instruction. She discovers that no one has written about this topic. Rather than panicking, she breaks down her research question into its component parts to consider what research might exist.

First, dance instruction: literature on how dance has traditionally been taught (i.e., not with AI) is still relevant because it will provide background and context. To appreciate the challenges or opportunities that transition to AI instruction might bring, we need to understand the status quo. Norah might also search for articles that analyse how other technological shifts have affected dance instruction: for example, how YouTube popularized at-home dance study, or how live video services like Zoom enabled real-time interaction between dance pupils and teachers despite physical distance.
Next, artificial intelligence used for instruction: Norah can seek out research on, and examples of, the application of AI for instructive purposes. Even if those purposes don't involve dance, such literature can contribute to illustrating the broader context around Norah's project.
Could it be relevant to discuss the technologies used to track an actor's real-life movements and convert them into the motions of a video game character? Perhaps there are parallels!
Could it be relevant to explore research on applications of AI in creative writing and visual art? Could be relevant since dance is also a creative field!

In summary, don't panic if you can't find research on your exact question or topic. Think through the broader context and parallel ideas, and you will soon find what you need.

Q: What if my discipline doesn't require a literature review chapter?

A: This is a great question. Whilst many disciplines dictate that your dissertation should include a chapter called Literature Review , not all subjects follow this convention. Those subjects will still expect you to incorporate a range of external literature, but you will nest the sources under different headings.

For example, some disciplines dictate an introductory chapter that is longer than average, and you essentially nest a miniature literature review inside the introduction, itself. Although the writing is more condensed and falls under a subheading of the introduction, the techniques and principles of writing a literature review (for example, moving from the broad to the narrow) will still prove relevant.

Some disciplines include chapters with names like Background , History , Theoretical Framework , etc. The exact functions of such chapters differ, but they have this in common: reviewing literature. You can't provide a critical background or history without synthesizing external sources. To illustrate your theoretical framework, you need to synthesize a range of literature that defines the theory or theories you intend to use.

Therefore, as stated earlier in this guide, you should be prepared to review and synthesize a range of literature regardless of your discipline. You can tailor the purpose of that synthesis to the structure and demands of writing in your subject area.

Q: Does my literature review need to include every source I plan to use in my discussion chapter?

A: The short answer is 'no' - there are some situations in which it is okay to use a source in your discussion chapter that you didn't integrate into your literature review chapter.

Imagine, for example, that your study produced a surprising result: a finding that you didn't anticipate. To make sense of that result, you might need to conduct additional research. That new research will help you explain the unexpected result in your discussion chapter.

More often, however, your discussion will draw on, or return to, sources from your literature review. After all, the literature review is where you paint a detailed picture of the conversation surrounding your research topic. Thus, it makes sense for you to relate your own work to that conversation in the discussion.

The literature review provides you an opportunity to engage with a rich range of published work and, perhaps for the first time, critically consider how your own research fits within and responds to your academic community. This can be a very invigorating process!

At the same time, it's likely that you will be juggling more academic sources than you have ever used in a single writing project. Additionally, you will need to think strategically about the focus and scope of your work: figuring out the best structure for your literature review might require several rounds of re-drafting and significant edits.

If you are usually a 'dive in without a plan and just get drafting' kind of writer, be prepared to modify your approach if you start to feel overwhelmed. Mind mapping, organising your ideas on a marker board, or creating a bullet-pointed reverse outline can help if you start to feel lost.

Alternately, if you are usually a 'create a strict, detailed outline and stick to it at all costs' kind of writer, keep in mind that long-form writing often calls for writers to modify their plans for content and structure as their work progresses and evolves. It can help such writers to schedule periodic 'audits' of their outlines, with the aim being to assess what is still working and what else needs to be added, deleted or modified.

Here’s a final checklist for writing your literature review. Remember that not all of these points will be relevant for your literature review, so make sure you cover whatever’s appropriate for your dissertation. The asterisk (*) indicates any content that might not be relevant for your dissertation. You can save your own copy of the checklist to edit using the Word document, below.

Writing a Literature Review

Welcome to the Purdue OWL

This page is brought to you by the OWL at Purdue University. When printing this page, you must include the entire legal notice.

A literature review is a document or section of a document that collects key sources on a topic and discusses those sources in conversation with each other (also called synthesis ). The lit review is an important genre in many disciplines, not just literature (i.e., the study of works of literature such as novels and plays). When we say “literature review” or refer to “the literature,” we are talking about the research ( scholarship ) in a given field. You will often see the terms “the research,” “the scholarship,” and “the literature” used mostly interchangeably.

Where, when, and why would I write a lit review?

There are a number of different situations where you might write a literature review, each with slightly different expectations; different disciplines, too, have field-specific expectations for what a literature review is and does. For instance, in the humanities, authors might include more overt argumentation and interpretation of source material in their literature reviews, whereas in the sciences, authors are more likely to report study designs and results in their literature reviews; these differences reflect these disciplines’ purposes and conventions in scholarship. You should always look at examples from your own discipline and talk to professors or mentors in your field to be sure you understand your discipline’s conventions, for literature reviews as well as for any other genre.

A literature review can be a part of a research paper or scholarly article, usually falling after the introduction and before the research methods sections. In these cases, the lit review just needs to cover scholarship that is important to the issue you are writing about; sometimes it will also cover key sources that informed your research methodology.

Lit reviews can also be standalone pieces, either as assignments in a class or as publications. In a class, a lit review may be assigned to help students familiarize themselves with a topic and with scholarship in their field, get an idea of the other researchers working on the topic they’re interested in, find gaps in existing research in order to propose new projects, and/or develop a theoretical framework and methodology for later research. As a publication, a lit review usually is meant to help make other scholars’ lives easier by collecting and summarizing, synthesizing, and analyzing existing research on a topic. This can be especially helpful for students or scholars getting into a new research area, or for directing an entire community of scholars toward questions that have not yet been answered.

What are the parts of a lit review?

Most lit reviews use a basic introduction-body-conclusion structure; if your lit review is part of a larger paper, the introduction and conclusion pieces may be just a few sentences while you focus most of your attention on the body. If your lit review is a standalone piece, the introduction and conclusion take up more space and give you a place to discuss your goals, research methods, and conclusions separately from where you discuss the literature itself.

Introduction:

An introductory paragraph that explains what your working topic and thesis is
A forecast of key topics or texts that will appear in the review
Potentially, a description of how you found sources and how you analyzed them for inclusion and discussion in the review (more often found in published, standalone literature reviews than in lit review sections in an article or research paper)
Summarize and synthesize: Give an overview of the main points of each source and combine them into a coherent whole
Analyze and interpret: Don’t just paraphrase other researchers – add your own interpretations where possible, discussing the significance of findings in relation to the literature as a whole
Critically Evaluate: Mention the strengths and weaknesses of your sources
Write in well-structured paragraphs: Use transition words and topic sentence to draw connections, comparisons, and contrasts.

Conclusion:

Summarize the key findings you have taken from the literature and emphasize their significance
Connect it back to your primary research question

How should I organize my lit review?

Lit reviews can take many different organizational patterns depending on what you are trying to accomplish with the review. Here are some examples:

Chronological : The simplest approach is to trace the development of the topic over time, which helps familiarize the audience with the topic (for instance if you are introducing something that is not commonly known in your field). If you choose this strategy, be careful to avoid simply listing and summarizing sources in order. Try to analyze the patterns, turning points, and key debates that have shaped the direction of the field. Give your interpretation of how and why certain developments occurred (as mentioned previously, this may not be appropriate in your discipline — check with a teacher or mentor if you’re unsure).
Thematic : If you have found some recurring central themes that you will continue working with throughout your piece, you can organize your literature review into subsections that address different aspects of the topic. For example, if you are reviewing literature about women and religion, key themes can include the role of women in churches and the religious attitude towards women.
Qualitative versus quantitative research
Empirical versus theoretical scholarship
Divide the research by sociological, historical, or cultural sources
Theoretical : In many humanities articles, the literature review is the foundation for the theoretical framework. You can use it to discuss various theories, models, and definitions of key concepts. You can argue for the relevance of a specific theoretical approach or combine various theorical concepts to create a framework for your research.

What are some strategies or tips I can use while writing my lit review?

Any lit review is only as good as the research it discusses; make sure your sources are well-chosen and your research is thorough. Don’t be afraid to do more research if you discover a new thread as you’re writing. More info on the research process is available in our "Conducting Research" resources .

As you’re doing your research, create an annotated bibliography ( see our page on the this type of document ). Much of the information used in an annotated bibliography can be used also in a literature review, so you’ll be not only partially drafting your lit review as you research, but also developing your sense of the larger conversation going on among scholars, professionals, and any other stakeholders in your topic.

Usually you will need to synthesize research rather than just summarizing it. This means drawing connections between sources to create a picture of the scholarly conversation on a topic over time. Many student writers struggle to synthesize because they feel they don’t have anything to add to the scholars they are citing; here are some strategies to help you:

It often helps to remember that the point of these kinds of syntheses is to show your readers how you understand your research, to help them read the rest of your paper.
Writing teachers often say synthesis is like hosting a dinner party: imagine all your sources are together in a room, discussing your topic. What are they saying to each other?
Look at the in-text citations in each paragraph. Are you citing just one source for each paragraph? This usually indicates summary only. When you have multiple sources cited in a paragraph, you are more likely to be synthesizing them (not always, but often
Read more about synthesis here.

The most interesting literature reviews are often written as arguments (again, as mentioned at the beginning of the page, this is discipline-specific and doesn’t work for all situations). Often, the literature review is where you can establish your research as filling a particular gap or as relevant in a particular way. You have some chance to do this in your introduction in an article, but the literature review section gives a more extended opportunity to establish the conversation in the way you would like your readers to see it. You can choose the intellectual lineage you would like to be part of and whose definitions matter most to your thinking (mostly humanities-specific, but this goes for sciences as well). In addressing these points, you argue for your place in the conversation, which tends to make the lit review more compelling than a simple reporting of other sources.

How to Structure Your Literature Review - Quick Guide with Examples

A literature review is a process of reviewing the existing scholarly literature based on a specific topic. It is one of the critical components of your own research paper. By conducting a thorough literature review, you will get a synopsis of the relevant methods, theories, and research gaps of the existing research on the related topic.

However, writing a good literature review is not as easy as it sounds. It requires rigorous research and extensive exploration of hundreds of journal articles to land on the pertinent information. So, it’s essential to learn the components of a literature review structure before you start writing one.

That’s why this article exists — to help you understand how to structure a literature review in a research paper. Read through the article to get the gist of the components used and how to structure them.

Role of literature review structure in research

Why do you think structuring your literature review is crucial in your research? It plays a significant role in organizing and presenting the research evidence and information effectively to the readers.

A well-structured literature review ensures clarity and coherence in the research which enables readers to follow the logical flow of ideas. It helps researchers to logically present their arguments and findings, making it easier for readers to comprehend the research's context and contribution.

Furthermore, it aids in identifying relationships between diverse studies, identifying key themes, and highlighting any research gaps. In fact, one of the prominent reasons why the proper format of a literature review is important is that it provides a framework for the researchers to present their ideas in a systematic and organized sequence.

Overall, a well structured literature review provides a roadmap for readers to navigate through the existing research or existing knowledge. By clearly indicating the main sections and sub-sections of the research, readers can easily locate the information they are interested in.

It is essential for researchers who are conducting a literature review to gain an overview of a specific topic or to find relevant studies and build a concrete framework for their research.

When should I structure my literature review?

Writing and structuring a literature review imparts the required knowledge to the readers only when you do it at the right time. So, be sure to map out the structure after you conduct a thorough literature review of the existing sources.

You should structure the review once you’re done with reading and digesting the research papers and before you start writing your thesis, dissertation, or research paper. It bridges the gap between reviewing literature and writing a research paper.

In simpler words, once you’ve comprehended the existing literature and gained enough knowledge of the theories, key concepts, and research gaps of your study or topic, you will be in a position to map out a literature review structure. It gives you a boost to set the stage for your research paper writing. Once the structure is ready, you can reiterate or restructure it based on the flow of your research work.

Tip: Use SciSpace Literature Review to compare and contrast multiple research papers on a single screen, saving a significant amount of time. And to comprehend the research papers easily, utilize Copilot which explains even the most complicated nomenclature and context in the simplest way possible. Above all, these tools support 75+ languages making your literature review and research paper reading a breeze.

How to structure a literature review?

A literature review is also one of the chapters or sections in your research paper. The structure varies from one study to another depending on diverse factors. However, a typical structure of a literature review has 3 main parts — an introduction, a body, and a conclusion. Let's get into them in detail.

a) Introduction of the literature review

The literature review introduction should give the readers an overview of what will you cover in the study and how the study is correlated. Ideally, it should provide the outline of your research and also explain the scope of your literature review. The introduction section is the most suitable segment to share your stance or perspective about the research topic and gently convey your contributions to the field through this study.

Since it happens to be the first paragraph, you must include and define its purpose, organization, and critical aspects of your research project.

Your introduction should give the following relevant background information to the readers:

The “why” of the review? — should provide a reason for why you’re writing the review
The “takeaway” of the review? — should portray the importance of the research
Articulate the topics covered in the research in a sequential manner
“What” of the review? — scope of the review
How or where your topic is aligned with the niche or subject area

b) Body of the literature reviews

The format and structure of the central body part are of utmost importance in writing a good literature review.. This is the section where you summarize, synthesize, analyze, and critically evaluate your research work. Therefore, you must use sections and subsections to divide the body for each methodological approach or theme aspect of further research.

In this part, you will have to organize and present your discussion in a clear and coherent manner. There are different types of structural approaches to adhere to while organizing the main body part of the literature review. Let’s explore the types based on the length and format of your review.

i) Chronological literature reviews

The chronological approach to building literature review format has been described as one of the most straightforward approaches. It helps you articulate the growth and development of the research topic over time in chronological order.

However, do not restrict yourself to just making a list or summarizing the reference resources. Instead, write a brief discussion and analysis of the critical arguments, research, and trends that have shaped the current status of your research topic.

Additionally, you must provide an interpretation of these events in your curated version. This approach gives you a space to discuss the latest developments, key debates, trends, and gaps focused on your research topic.

Example: Locoregional Management of Breast Cancer: A Chronological Review This chronological review discusses the evolution of locoregional management through some key clinical trials and aims to highlight important points in the time period in which the evidence was generated and emphasize the 10-year outcomes for the comparability of results.

ii) Thematic literature review

The thematic literature review is the best way to structure your literature review based on the theme or category of your research. The format of a literature review is structured in sections and sub-sections based on the observed themes or patterns in your review.

Every part stays dedicated to presenting a different aspect of your chosen topic. For example, if you’re working on a topic of climatic conditions in Nigeria, you might find themes such as monsoon climate, tropical savannah climate, and so on. Unlike the chronological approach, the primary focus here is on different aspects of a particular topic, or issue instead of the progression of certain events. Example: A Thematic Review of Current Literature Examining Evidence-Based Practices and Inclusion

This paper provides a thematic summary of current literature combining the topics of evidence-based practices (EBPs) and inclusive settings and summarizes key findings from 27 peer-reviewed articles written in English and published between 2012-2022.

iii) Methodological literature review

The methodological approach helps you formulate the structure of a literature review based on the research methodologies used. These methodologies could be qualitative, quantitative, or mixed. You can present your literature review structure in a form by showing a comparison between crucial findings, gatherings, and outcomes from different research methods.

If you’re working on research derived from different disciplines and methodologies, this approach would be more suitable to structure your literature review. This method majorly focuses on the type of analysis method used in the research (quantitative, qualitative, and mixed).

Example: Methodological review to develop a list of bias items used to assess reviews incorporating network meta-analysis: protocol and rationale

The methodological review aims to develop a list of items relating to biases in reviews with NMA, which will inform a new tool to assess the risk of bias in NMAs, and potentially other reporting or quality checklists for NMAs that are being updated.

iv) Theoretical literature review

Theoretical literature reviews are often used to discuss and analyze vital concepts and theories. Adopting this approach such a way that, you can significantly put forth the relevance and critical findings of a particular field or theoretical method. Proceeding in the same way, you can also outline an entirely new research framework.

Example: Theoretical Review Study: Peran Dan Fungsi Mutu Pelayanan Kesehatan Di Rumah Sakit

This paper analyzes various theories on the role and function of quality management in hospitals, where the authors investigate how the role and functions of the quality of health services in hospitals.

c) Conclusion of the literature review

The conclusion of your literature review must be focused on your key findings, and their results, and an elaborate emphasis on the significance of all aspects. Describing the research gaps and your contributions can be helpful in case you are writing a dissertation or thesis.

Moreover, you must specify the procedure and research methodology for developing the framework of your research topic. Additionally, if the relevant literature review is a standalone assignment for you, present the conclusion centered on the implications and suggestions for future references.

Lastly, you must ensure that your research paper does not lack any critical aspects and must not contain any grammatical or spelling mistakes. For this, you must proofread and edit it to perfection.

Overall, your conclusion should provide the reader with the following information:

Provide an overview of the literature review.
Highlight key areas for future research on the topic.
Establish a connection between the review and your research.

Tip: Keep this checklist handy before writing your literature review!

Outline the purpose and scope of the study
Identify relevant and credible scholarly sources (research papers/literature)
Use AI tools to streamline the literature review process
Capture the bibliographical details of the sources
Analyze and interpret the findings
Identify research gaps in the literature
Investigate methodologies/theories/hypotheses
Brainstorm and research multiple standpoints
Craft an introduction, a body, and a conclusion
Final proofreading and all set!!

Wrapping up!

If you are working on your thesis, ensure to emphasize structuring your literature reviews and be keen in presenting it in a clear, coherent, and organized manner. The structure of a literature review is critical as it assists researchers in building upon existing knowledge, creating a theoretical framework, identifying relationships between studies, highlighting key concepts, and guiding readers through the research.

Scientific research can be made more accessible, informative, and impactful by structuring the literature review according to the different types of approaches discussed in this blog.

Frequently Asked Questions

When conducting a literature review, it's important to avoid:

1.Disorganization: Keep your review structured and coherent.

2.Lack of alignment: Ensure that your review aligns with your research objectives and questions.

3.Lack of synthesis: Connect and integrate the findings from different sources rather than presenting them in isolation.

Common challenges we encounter while organizing a literature review include:

1.Managing an exhaustive volume of scientific publications.

2.Ensuring coherence and flow between different sections.

3.Striving to maintain objectivity and relevance to your research topic.

When structuring a literature review, you should avoid including irrelevant or outdated sources, biased information, and repetitive content.

No, a literature review is typically not arranged in alphabetical order. Instead, it's usually organized thematically, chronologically, or by relevance to the research topic.

Structure of a literature review

A literature review should have an introduction, main body and a conclusion.

As shown in the video, above, the body should NOT be organised author by author (for that, there are annotated bibliographies ). Instead, it should be organised by topic (normally, from general background to specific aspects of the subject your dissertation is dealing with). Some paragraphs can be organised chronologically (for example outlining the development of an idea throughout time), by method, by sector, or other criteria.

Introduction

This should be a paragraph that can include some of the following:

Outlining the scope of your literature review – sources, topics to be discussed / the aims of your review.

Where/how does your topic fit into the wider subject area.

Why the topic is important- is it an area of current interest/significance?

Highlight the relevant issues or debates that have characterised your field of research.

Has the topic been widely researched? Or not?

Signposting for the reader, explaining the organisation / sequence of topics covered in the review.

Provide strong sentences at beginnings of paragraphs: every paragraph shall deal with a topic or make a point.

Signpost, showing the direction of your writing, and indicating your critical take on the sources you present.

Use you own voice to comment on and evaluate the literature.

Identify gaps in the literature.

Write "so what" summary sentences throughout the review to help the reader understand how the sections of your review are relevant to your research.

Use language to show confidence or caution, as appropriate: e.g. There is clearly a link... OR This suggests a possible link...

Avoid "he/she said...": always name the authors. Vary the reporting words. See the guide on Academic Voice and Language for more guidance on logic, signposting, reporting words etc.

Conclusion

State how your literature review has met the review aim(s) outlined in the introduction.

Summarise and synthesise the main issues/themes that the literature review has presented in relation to your topic area and research questions.

If the literature review is part of a dissertation, underline the gaps identified in the literature. This provides a rationale for your chosen dissertation topic.

The structure of a literature review

A literature review should be structured like any other essay: it should have an introduction, a middle or main body, and a conclusion.

Introduction

The introduction should:

define your topic and provide an appropriate context for reviewing the literature;
establish your reasons – i.e. point of view – for
reviewing the literature;
explain the organisation – i.e. sequence – of the review;
state the scope of the review – i.e. what is included and what isn’t included. For example, if you were reviewing the literature on obesity in children you might say something like: There are a large number of studies of obesity trends in the general population. However, since the focus of this research is on obesity in children, these will not be reviewed in detail and will only be referred to as appropriate.

The middle or main body should:

organise the literature according to common themes;
provide insight into the relation between your chosen topic and the wider subject area e.g. between obesity in children and obesity in general;
move from a general, wider view of the literature being reviewed to the specific focus of your research.

The conclusion should:

summarise the important aspects of the existing body of literature;
evaluate the current state of the literature reviewed;
identify significant flaws or gaps in existing knowledge;
outline areas for future study;
link your research to existing knowledge.

Ten Simple Rules for Writing a Literature Review

Marco pautasso.

1 Centre for Functional and Evolutionary Ecology (CEFE), CNRS, Montpellier, France

2 Centre for Biodiversity Synthesis and Analysis (CESAB), FRB, Aix-en-Provence, France

Literature reviews are in great demand in most scientific fields. Their need stems from the ever-increasing output of scientific publications [1] . For example, compared to 1991, in 2008 three, eight, and forty times more papers were indexed in Web of Science on malaria, obesity, and biodiversity, respectively [2] . Given such mountains of papers, scientists cannot be expected to examine in detail every single new paper relevant to their interests [3] . Thus, it is both advantageous and necessary to rely on regular summaries of the recent literature. Although recognition for scientists mainly comes from primary research, timely literature reviews can lead to new synthetic insights and are often widely read [4] . For such summaries to be useful, however, they need to be compiled in a professional way [5] .

When starting from scratch, reviewing the literature can require a titanic amount of work. That is why researchers who have spent their career working on a certain research issue are in a perfect position to review that literature. Some graduate schools are now offering courses in reviewing the literature, given that most research students start their project by producing an overview of what has already been done on their research issue [6] . However, it is likely that most scientists have not thought in detail about how to approach and carry out a literature review.

Reviewing the literature requires the ability to juggle multiple tasks, from finding and evaluating relevant material to synthesising information from various sources, from critical thinking to paraphrasing, evaluating, and citation skills [7] . In this contribution, I share ten simple rules I learned working on about 25 literature reviews as a PhD and postdoctoral student. Ideas and insights also come from discussions with coauthors and colleagues, as well as feedback from reviewers and editors.

Rule 1: Define a Topic and Audience

How to choose which topic to review? There are so many issues in contemporary science that you could spend a lifetime of attending conferences and reading the literature just pondering what to review. On the one hand, if you take several years to choose, several other people may have had the same idea in the meantime. On the other hand, only a well-considered topic is likely to lead to a brilliant literature review [8] . The topic must at least be:

interesting to you (ideally, you should have come across a series of recent papers related to your line of work that call for a critical summary),
an important aspect of the field (so that many readers will be interested in the review and there will be enough material to write it), and
a well-defined issue (otherwise you could potentially include thousands of publications, which would make the review unhelpful).

Ideas for potential reviews may come from papers providing lists of key research questions to be answered [9] , but also from serendipitous moments during desultory reading and discussions. In addition to choosing your topic, you should also select a target audience. In many cases, the topic (e.g., web services in computational biology) will automatically define an audience (e.g., computational biologists), but that same topic may also be of interest to neighbouring fields (e.g., computer science, biology, etc.).

Rule 2: Search and Re-search the Literature

After having chosen your topic and audience, start by checking the literature and downloading relevant papers. Five pieces of advice here:

keep track of the search items you use (so that your search can be replicated [10] ),
keep a list of papers whose pdfs you cannot access immediately (so as to retrieve them later with alternative strategies),
use a paper management system (e.g., Mendeley, Papers, Qiqqa, Sente),
define early in the process some criteria for exclusion of irrelevant papers (these criteria can then be described in the review to help define its scope), and
do not just look for research papers in the area you wish to review, but also seek previous reviews.

The chances are high that someone will already have published a literature review ( Figure 1 ), if not exactly on the issue you are planning to tackle, at least on a related topic. If there are already a few or several reviews of the literature on your issue, my advice is not to give up, but to carry on with your own literature review,

An external file that holds a picture, illustration, etc.
Object name is pcbi.1003149.g001.jpg

The bottom-right situation (many literature reviews but few research papers) is not just a theoretical situation; it applies, for example, to the study of the impacts of climate change on plant diseases, where there appear to be more literature reviews than research studies [33] .

discussing in your review the approaches, limitations, and conclusions of past reviews,
trying to find a new angle that has not been covered adequately in the previous reviews, and
incorporating new material that has inevitably accumulated since their appearance.

When searching the literature for pertinent papers and reviews, the usual rules apply:

be thorough,
use different keywords and database sources (e.g., DBLP, Google Scholar, ISI Proceedings, JSTOR Search, Medline, Scopus, Web of Science), and
look at who has cited past relevant papers and book chapters.

Rule 3: Take Notes While Reading

If you read the papers first, and only afterwards start writing the review, you will need a very good memory to remember who wrote what, and what your impressions and associations were while reading each single paper. My advice is, while reading, to start writing down interesting pieces of information, insights about how to organize the review, and thoughts on what to write. This way, by the time you have read the literature you selected, you will already have a rough draft of the review.

Of course, this draft will still need much rewriting, restructuring, and rethinking to obtain a text with a coherent argument [11] , but you will have avoided the danger posed by staring at a blank document. Be careful when taking notes to use quotation marks if you are provisionally copying verbatim from the literature. It is advisable then to reformulate such quotes with your own words in the final draft. It is important to be careful in noting the references already at this stage, so as to avoid misattributions. Using referencing software from the very beginning of your endeavour will save you time.

Rule 4: Choose the Type of Review You Wish to Write

After having taken notes while reading the literature, you will have a rough idea of the amount of material available for the review. This is probably a good time to decide whether to go for a mini- or a full review. Some journals are now favouring the publication of rather short reviews focusing on the last few years, with a limit on the number of words and citations. A mini-review is not necessarily a minor review: it may well attract more attention from busy readers, although it will inevitably simplify some issues and leave out some relevant material due to space limitations. A full review will have the advantage of more freedom to cover in detail the complexities of a particular scientific development, but may then be left in the pile of the very important papers “to be read” by readers with little time to spare for major monographs.

There is probably a continuum between mini- and full reviews. The same point applies to the dichotomy of descriptive vs. integrative reviews. While descriptive reviews focus on the methodology, findings, and interpretation of each reviewed study, integrative reviews attempt to find common ideas and concepts from the reviewed material [12] . A similar distinction exists between narrative and systematic reviews: while narrative reviews are qualitative, systematic reviews attempt to test a hypothesis based on the published evidence, which is gathered using a predefined protocol to reduce bias [13] , [14] . When systematic reviews analyse quantitative results in a quantitative way, they become meta-analyses. The choice between different review types will have to be made on a case-by-case basis, depending not just on the nature of the material found and the preferences of the target journal(s), but also on the time available to write the review and the number of coauthors [15] .

Rule 5: Keep the Review Focused, but Make It of Broad Interest

Whether your plan is to write a mini- or a full review, it is good advice to keep it focused 16 , 17 . Including material just for the sake of it can easily lead to reviews that are trying to do too many things at once. The need to keep a review focused can be problematic for interdisciplinary reviews, where the aim is to bridge the gap between fields [18] . If you are writing a review on, for example, how epidemiological approaches are used in modelling the spread of ideas, you may be inclined to include material from both parent fields, epidemiology and the study of cultural diffusion. This may be necessary to some extent, but in this case a focused review would only deal in detail with those studies at the interface between epidemiology and the spread of ideas.

While focus is an important feature of a successful review, this requirement has to be balanced with the need to make the review relevant to a broad audience. This square may be circled by discussing the wider implications of the reviewed topic for other disciplines.

Rule 6: Be Critical and Consistent

Reviewing the literature is not stamp collecting. A good review does not just summarize the literature, but discusses it critically, identifies methodological problems, and points out research gaps [19] . After having read a review of the literature, a reader should have a rough idea of:

the major achievements in the reviewed field,
the main areas of debate, and
the outstanding research questions.

It is challenging to achieve a successful review on all these fronts. A solution can be to involve a set of complementary coauthors: some people are excellent at mapping what has been achieved, some others are very good at identifying dark clouds on the horizon, and some have instead a knack at predicting where solutions are going to come from. If your journal club has exactly this sort of team, then you should definitely write a review of the literature! In addition to critical thinking, a literature review needs consistency, for example in the choice of passive vs. active voice and present vs. past tense.

Rule 7: Find a Logical Structure

Like a well-baked cake, a good review has a number of telling features: it is worth the reader's time, timely, systematic, well written, focused, and critical. It also needs a good structure. With reviews, the usual subdivision of research papers into introduction, methods, results, and discussion does not work or is rarely used. However, a general introduction of the context and, toward the end, a recapitulation of the main points covered and take-home messages make sense also in the case of reviews. For systematic reviews, there is a trend towards including information about how the literature was searched (database, keywords, time limits) [20] .

How can you organize the flow of the main body of the review so that the reader will be drawn into and guided through it? It is generally helpful to draw a conceptual scheme of the review, e.g., with mind-mapping techniques. Such diagrams can help recognize a logical way to order and link the various sections of a review [21] . This is the case not just at the writing stage, but also for readers if the diagram is included in the review as a figure. A careful selection of diagrams and figures relevant to the reviewed topic can be very helpful to structure the text too [22] .

Rule 8: Make Use of Feedback

Reviews of the literature are normally peer-reviewed in the same way as research papers, and rightly so [23] . As a rule, incorporating feedback from reviewers greatly helps improve a review draft. Having read the review with a fresh mind, reviewers may spot inaccuracies, inconsistencies, and ambiguities that had not been noticed by the writers due to rereading the typescript too many times. It is however advisable to reread the draft one more time before submission, as a last-minute correction of typos, leaps, and muddled sentences may enable the reviewers to focus on providing advice on the content rather than the form.

Feedback is vital to writing a good review, and should be sought from a variety of colleagues, so as to obtain a diversity of views on the draft. This may lead in some cases to conflicting views on the merits of the paper, and on how to improve it, but such a situation is better than the absence of feedback. A diversity of feedback perspectives on a literature review can help identify where the consensus view stands in the landscape of the current scientific understanding of an issue [24] .

Rule 9: Include Your Own Relevant Research, but Be Objective

In many cases, reviewers of the literature will have published studies relevant to the review they are writing. This could create a conflict of interest: how can reviewers report objectively on their own work [25] ? Some scientists may be overly enthusiastic about what they have published, and thus risk giving too much importance to their own findings in the review. However, bias could also occur in the other direction: some scientists may be unduly dismissive of their own achievements, so that they will tend to downplay their contribution (if any) to a field when reviewing it.

In general, a review of the literature should neither be a public relations brochure nor an exercise in competitive self-denial. If a reviewer is up to the job of producing a well-organized and methodical review, which flows well and provides a service to the readership, then it should be possible to be objective in reviewing one's own relevant findings. In reviews written by multiple authors, this may be achieved by assigning the review of the results of a coauthor to different coauthors.

Rule 10: Be Up-to-Date, but Do Not Forget Older Studies

Given the progressive acceleration in the publication of scientific papers, today's reviews of the literature need awareness not just of the overall direction and achievements of a field of inquiry, but also of the latest studies, so as not to become out-of-date before they have been published. Ideally, a literature review should not identify as a major research gap an issue that has just been addressed in a series of papers in press (the same applies, of course, to older, overlooked studies (“sleeping beauties” [26] )). This implies that literature reviewers would do well to keep an eye on electronic lists of papers in press, given that it can take months before these appear in scientific databases. Some reviews declare that they have scanned the literature up to a certain point in time, but given that peer review can be a rather lengthy process, a full search for newly appeared literature at the revision stage may be worthwhile. Assessing the contribution of papers that have just appeared is particularly challenging, because there is little perspective with which to gauge their significance and impact on further research and society.

Inevitably, new papers on the reviewed topic (including independently written literature reviews) will appear from all quarters after the review has been published, so that there may soon be the need for an updated review. But this is the nature of science [27] – [32] . I wish everybody good luck with writing a review of the literature.

How to Structure a Literature Review for a Dissertation

By Laura Brown on 26th February 2019

A literature review structure typically contains three essential parts,

Introduction: It provides an overview of the topic or research question being addressed, and explain the purpose and scope of the literature review.
Main Body: This section includes the methodology, themes/sections, and discussion/analysis. It provides a comprehensive analysis of the literature on a particular topic, synthesizes the findings, and identifies gaps or limitations in the literature.
Conclusion: Here, the researcher summarises the main findings, highlights the implications of the findings, addresses the limitations and provides recommendations for future research.

Basically, literature review is the assessment of the selected readings. You are often asked to write it for three purposes:

To review a book or an article, also known as a critical review.
To review a bunch of readings and summarise the key points that are termed as an annotated bibliography .
The last and main purpose is reviewing available literature chosen for a dissertation. This is called a literature review of a dissertation.

We have observed that students face numerous challenges when they structure a literature review paper and are left with no option but to buy literature review online. This blog will solve your problems, and we will briefly tell you how to structure a dissertation literature review .

Things Which Makes A Literature Review Good

How to write a good dissertation literature review.

Writing a literature review can be a daunting task, but it is an essential part of any research project. A well-written literature review provides a thorough understanding of the research field, identifies gaps in the existing literature, and helps to establish the importance of proposed research project. Here are some tips to help you structure your literature review effectively:

A. Start with a clear introduction

In a proper structure for literature review, you should begin by providing a brief overview of the research area and the scope of your review. State the research questions or objectives that you aim to address through your literature review.

B. Identify the relevant literature

Conduct a comprehensive search of the literature using academic databases , such as Google Scholar , PubMed , and JSTOR . Identify the most relevant and recent studies, including theoretical and empirical research, to provide a comprehensive understanding of the research field.

C. Organise the literature

This is the most crucial part while you prepare the structure of literature review dissertation. Organise the literature based on themes, theories, or chronology. A thematic literature review groups the literature based on the key themes or key concepts that emerge from the literature.

A theoretical literature review evaluates the existing theories and frameworks in the research field. A chronological literature review presents the literature in form of publication, highlighting the historical perspective of the research field.

D. Critically evaluate the literature

Analyse the literature critically by comparing and contrasting different studies, highlighting their strengths and weaknesses, and identifying significant flaws, themes or gaps in existing knowledge. This will help you to establish the relevance and importance of your proposed research project.

E. Summarise the literature

Summarise the key findings by highlighting the main trends and themes that emerge from the literature. This will help you to provide a comprehensive overview of the research field and to establish the relevance of your proposed research project.

F. Write in a clear and concise style

Write your literature review in succinct manner, using appropriate academic language and referencing conventions. Ensure that your writing is well-structured and flows logically, with each paragraph focusing on a specific theme or aspect of the literature.

G. Conclude with a summary and future study

The final tip to structure a literature review of dissertation is to conclude your literature review by summarising the key findings and conclusions of the literature, highlighting any gaps or inconsistencies, and identifying the future directions for research in the field.
