Co-witnesses and the effects of discussion on eyewitness memory by Helen M Paterson

Overview of thesis (introduction)

This introductory section is less than two pages long.

The first paragraph:

• states the overall objective of the thesis
• defines the introduced term
• provides broad motivation for interest in the area
• introduces the sections of the thesis that will address the overall objective.

The other paragraphs describe the content and purpose of each section of the thesis.

Literature review

The literature review is made of up of two chapters.

Chapter 1: Literature review of relevant research

The overall goals of this chapter are to firstly establish the significance of the general field of study, and then identify a place where a new contribution could be made.

The bulk of the chapter critically evaluates the methodologies used in this field to identify the appropriate approach for investigating the research questions.

Chapter 2: Theoretical explanations of memory conformity

Chapter 5, study 3: co-witness contamination.

This chapter has the following structure:

• Introduction
• Discussion.

The introduction introduces the particular study to be reported on, and includes a three-and-a-half page literature review.

The literature review in this chapter:

• links back to the relevant general findings of the earlier literature review chapters
• briefly reviews the broad motivation for this study
• identifies that two previously used methodologies in this field will be compared to resolve questions about the findings of previous studies which had only used a single methodology
• uses previous literature to generate specific hypotheses to test
• reviews additional literature to provide a justification for a second objective to be investigated in the study reported on in this chapter.

Published on 22 February 2022 by Shona McCombes . Revised on 7 June 2022.

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.

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 summarise sources – it analyses, synthesises, 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 dissertation or thesis, you will 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 scholarly context
• Develop a theoretical framework and methodology for your research
• Position yourself in relation to other researchers and theorists
• Show how your dissertation addresses a gap or contributes to a debate

You might also have to write a literature review as a stand-alone assignment. In this case, the purpose is to evaluate the current state of research and demonstrate your knowledge of scholarly debates around a topic.

The content will look slightly different in each case, but the process of conducting a literature review follows the same steps. 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 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
• Generation Z, teenagers, adolescents, youth

Search for relevant sources

Use your keywords to begin searching for sources. Some 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 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!

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’s important to keep track of your sources with references to avoid plagiarism . It can be helpful to make an annotated bibliography, where you compile full reference 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.

You can use our free APA Reference Generator for quick, correct, consistent citations.

Prevent plagiarism, run a free check.

To begin organising your literature review’s argument and structure, you need to 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 organising the body of a literature review. You should have a rough idea of your strategy before you start writing.

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 summarising sources in order.

Try to analyse 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 organise 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.

If you are writing the literature review as part of your dissertation or thesis, reiterate your central problem or research question and give a brief summary of the scholarly context. You can emphasise the timeliness of the topic (“many recent studies have focused on the problem of x”) or highlight a gap in the literature (“while there has been much research on x, few researchers have taken y into consideration”).

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, make sure to follow these tips:

• Summarise and synthesise: give an overview of the main points of each source and combine them into a coherent whole.
• Analyse and interpret: don’t just paraphrase other researchers – add your own interpretations, 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 transitions and topic sentences to draw connections, comparisons and contrasts.

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

If the literature review is part of your dissertation or thesis, reiterate how your research addresses gaps and contributes new knowledge, or discuss how you have drawn on existing theories and methods to build a framework for your research. This can lead directly into your methodology section.

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 dissertation , thesis, research paper , or proposal .

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

• To familiarise 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  dissertation . After the introduction , it grounds your research in a scholarly field and leads directly to your theoretical framework or methodology .

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.

Wrestling an elephant into a cupboard: how to write a PhD literature review in nine easy steps

Feb 10, 2019

When I was writing my PhD I hated the literature review. I was scared of it. One day, my supervisor took me to one side and told me that I had no choice: ‘It was going to have to be done before you start fieldwork’. I was terrified.

Sound familiar? According to Google, 5,000 people a month search for advice on how to conduct a literature review. And we know from the one-on-one PhD coaching we offer and from the theses we proofread that many students struggle with this part of their thesis. 

If you’re feeling lost, keep reading. In this guide, I’ll walk you through the nine steps involved in conducting and writing a PhD literature review.

You’ll realise what I eventually found out: C onducting a literature review is easy. Okay, perhaps that’s a bit much. Let me rephrase: Conducting a PhD literature review isn’t as hard as you think.

What a PhD literature review isn’t

Let us make one thing very clear. A PhD literature review isn’t just a summary of existing literature. That’s an annotated bibliography and that isn’t what a PhD literature review is about. This is the mistake I see most frequently in the PhDs I proofread.

Not only will your examiners send this back for corrections, but it may mean the whole PhD thesis is problematic because it isn’t grounded in a critical review of the literature.

What a PhD literature review is

A PhD literature review is a critical assessment of the literature in your field and related to your specific research topic. When discussing each relevant piece of literature, the review must highlight where the gaps are and what the strengths and weaknesses are of particular studies, papers, books, etc. Also, different pieces of literature are compared and contrasted with one another so that themes and relationships are highlighted.

The job of a literature review is to show five things (if you’re using our PhD Writing Template , you may recognise these):

1. What has been written on your topic 2. Who the key authors are and what the key works are 3. The main theories and hypotheses 4. The main themes that exist in the literature 5. Gaps and weaknesses that your study will then help fill

Who cares what other people have written and said, or what they haven’t said? Well, you should and your examiners definitely will. For your own study to make sense, it has to be situated in the literature. That means you must relate it to what others are talking about.

If you wanted to build a new mobile phone, you would have to research how other mobile phones are built, find out where they can be improved and then design one that makes those improvements.

The literature review is the same.

But where do I start? Here, we list nine steps. Follow each and you’ll be on your way to literature review greatness.

We’ve made the infographic below to help you on your way. Click the image to download it.

Step One: Pick a Broad Topic

You will be reviewing literature on a particular topic, so knowing what your topic is beforehand means you can narrow down your search. At this stage your topic is broad. You won’t be able to know the specifics until you do the review itself.

For my PhD, which looked at the contributions that local government made to climate change policy, my literature review started with a broad topic of ‘climate change policy’. I didn’t focus in on local government until I had read the literature on climate change policy and realized there was a gap.

So, having a clearly defined purpose is really important. Otherwise you are searching blind. If you refer to your PhD Writing Template, take a look at the box titled ‘Aims & Objectives’ – you’ll need to make sure you have established your aims, scope and research questions.

Step Two: Find the Way In

If you search for your broad topic in Google Scholar, you’ll be presented with millions of results. With my own PhD, a search for ‘climate change policy’ bought up over 3 million results.

  Obviously it’s unfeasible to read through all these.

So where do you start? Easy: choose the biggest names in your field.

There are three ways to find these:

1. Textbooks 2. Review articles 3. Most-cited articles

Read through these seminal texts and you’ll begin to get an idea of the broad topic.

Step Three: Who’s Saying What & When

Your job at this stage is to find out the key debates in the field. 

• Who is making the most significant contribution?
• What are they saying?
• How are they saying it?
• What aren’t they saying?

Step Four: Notes, Notes, Notes.

Whenever you read anything you should be taking notes. Detailed notes. These need to cover the following points: 

• What is the author saying?
• How is it relevant to your research?
• What are the gaps/weaknesses?
• What are the key references that you should read?

The more of these kind of standardised notes you have, the easier it will be when you write your literature review.

Step Five: Narrow Down the Field

As you read the key texts, you will begin to see what the key debates are in your field. There might be a number of ’schools’, for example. When you become aware of them, start to focus your literature review around them.

Step Six: Filter Through Your Growing List of References

Don’t just read everything. You need to find a way to filter through the articles or books that are relevant. For example, scan the abstracts, introduction, keywords, titles and references.

Filter the sources you come across into three separate categories:

• Probably won’t read

Step Seven: Use Snowball Sampling

As you read through these articles, look at their reference list. Collect articles that you think will be relevant and use them in your literature review. This is known as snowball sampling.

Step Eight: Think About the Questions that Haven’t Been Asked

You must be reading critically, which means asking what the weaknesses are and where particular articles or book could be improved.

In order to tease out your own specific research topic, you need to think of the questions that haven’t been asked.

Master your lit review & theory framework.

Learn what goes where (and why), and how it all fit together with this free, interactive guide to the PhD literature review and theory framework.

Step Nine: Writing Up Your Literature Review

  The review will broadly follow the key debates you have spotted in step five above. As you write, focus on putting in more detail about particular sources (i.e. flesh out steps six and seven). The focus when writing is to elaborate upon the key patterns and themes that have emerged.

However, you need to include your own synthesis of the material. I said earlier that you shouldn’t just summarize the literature. Instead you should write critically. You should clearly and precisely present your argument. The argument will focus around the questions that haven’t been asked – step nine above – and will ground the literature review. We’ve written a guide to being critical in your literature review . You should read it if you’re unsure what’s required.

So, write early and write that first draft quickly. The earlier you start writing your literature review the better. You must accept that your first draft is going to be just that: a draft. When you write the first draft, focus on the broad structure first. This means focus on the broad themes you want to discuss in the review.

Something you need to consider is how to structure the chapter. The simple answer is that you can either structure it chronologically or thematically.

The long answer is that chronological literature reviews are restrictive and over-simplify the field. They are useful for very early drafts of the review and can help you to arrange the literature and trace threads and connections within it. However, your supervisors and examiners are looking for thematic reviews (unless they have told you otherwise), where you discuss the literature with reference to the themes that have emerged.

Equally important is knowing when to stop reviewing the literature.

The sooner you go out and do your fieldwork, the better. The literature review is a cruel mistress; you’ll struggle to fully nail down its various components and fully understand how everything you have read is related. But don’t despair; aspects of the literature review will become clearer when you enter the field and start to collect data.

Don’t fall into the trap of spending too long in the library and too little time doing fieldwork.

  It’s natural to be scared of the literature review. To conduct one, you have to read, process and synthesise hundreds of thousands of words. But it’s not impossible. Keep this guide to hand and refer to it when you feel yourself getting lost. Share it with your colleagues so they too can conquer their fear of the literature review.

How to write a superb literature review

Andy Tay is a freelance writer based in Singapore.

Literature reviews are important resources for scientists. They provide historical context for a field while offering opinions on its future trajectory. Creating them can provide inspiration for one’s own research, as well as some practice in writing. But few scientists are trained in how to write a review — or in what constitutes an excellent one. Even picking the appropriate software to use can be an involved decision (see ‘Tools and techniques’). So Nature asked editors and working scientists with well-cited reviews for their tips.

How to write a literature review for a dissertation, published by steve tippins on july 5, 2019 july 5, 2019.

Last Updated on: 22nd May 2024, 04:06 am

Chapter 2 of your dissertation, your literature review, may be the longest chapter. It is not uncommon to see lit reviews in the 40- to 60-page range. That may seem daunting, but I contend that the literature review could be the easiest part of your dissertation.

It is also foundational. To be able to select an appropriate research topic and craft expert research questions, you’ll need to know what has already been discovered and what mysteries remain. 

Remember, your degree is meant to indicate your achieving the highest level of expertise in your area of study. The lit review for your dissertation could very well form the foundation for your entire career.

In this article, I’ll give you detailed instructions for how to write the literature review of your dissertation without stress. I’ll also provide a sample outline.

When to Write the Literature Review for your Dissertation

Though technically Chapter 2 of your dissertation, many students write their literature review first. Why? Because having a solid foundation in the research informs the way you write Chapter 1.

Also, when writing Chapter 1, you’ll need to become familiar with the literature anyway. It only makes sense to write down what you learn to form the start of your lit review.

Some institutions even encourage students to write Chapter 2 first. But it’s important to talk with your Chair to see what he or she recommends.

How Long Should a Literature Review Be?

There is no set length for a literature review. The length largely depends on your area of study. However, I have found that most literature reviews are between 40-60 pages.

If your literature review is significantly shorter than that, ask yourself (a) if there is other relevant research that you have not explored, or (b) if you have provided enough of a discussion about the information you did explore.

Preparing to Write the Literature Review for your Dissertation

Step 1. Search Using Key Terms

Most people start their lit review searching appropriate databases using key terms. For example, if you’re researching the impact of social media on adult learning, some key terms you would use at the start of your search would be adult learning, androgogy, social media, and “learning and social media” together. 

If your topic was the impact of natural disasters on stock prices, then you would need to explore all types of natural disasters, other market factors that impact stock prices, and the methodologies used. 

You can save time by skimming the abstracts first; if the article is not what you thought it might be you can move on quickly.

Once you start finding articles using key terms, two different things will usually happen: you will find new key terms to search, and the articles will lead you directly to other articles related to what you are studying. It becomes like a snowball rolling downhill. 

Note that the vast majority of your sources should be articles from peer-reviewed journals. 

Step 2. Immerse Yourself in the Literature

When people ask what they should do first for their dissertation the most common answer is “immerse yourself in the literature.” What exactly does this mean?

Think of this stage as a trip into the quiet heart of the forest. Your questions are at the center of this journey, and you’ll need to help your reader understand which trees — which particular theories, studies, and lines of reasoning — got you there. 

There are lots of trees in this particular forest, but there are particular trees that mark your path.  What makes them unique? What about J’s methodology made you choose that study over Y’s? How did B’s argument triumph over A’s, thus leading you to C’s theory? 

You are showing your reader that you’ve fully explored the forest of your topic and chosen this particular path, leading to these particular questions (your research questions), for these particular reasons.

Step 3. Consider Gaps in the Research

The gaps in the research are where current knowledge ends and your study begins. In order to build a case for doing your study, you must demonstrate that it:

• Is worthy of doctoral-level research, and
• Has not already been studied

Defining the gaps in the literature should help accomplish both aims. Identifying studies on related topics helps make the case that your study is relevant, since other researchers have conducted related studies.

And showing where they fall short will help make the case that your study is the appropriate next step. Pay special attention to the recommendations for further research that the authors of studies make.

Step 4. Organize What You Find

As you find articles, you will have to come up with methods to organize what you find. 

Whether you find a computer-based system (three popular systems are Zotero, endNote, and Mendeley) or some sort of manual system such as index cards, you need to devise a method where you can easily group your references by subject and methodology and find what you are looking for when you need it. It is very frustrating to know you have found an article that supports a point that you are trying to make, but you can’t find the article!

One way to save time and keep things organized is to cut and paste relevant quotations (and their references) under topic headings. You’ll be able to rearrange and do some paraphrasing later, but if you’ve got the quotations and the citations that are important to you already embedded in your text, you’ll have an easier time of it.  

If you choose this method, be sure to list the whole reference on the reference/bibliography page so you don’t have to do this page separately later. Some students use Scrivener for this purpose, as it offers a clear way to view and easily navigate to all sections of a written document.

How to Write the Literature Review for your Dissertation

Once you have gathered a sufficient number of pertinent references, you’ll need to string them together in a way that tells your story. Explain what previous researchers have done by telling the story of how knowledge on this topic has evolved. Here, you are laying the support for your topic and showing that your research questions need to be answered. Let’s dive into how to actually write your dissertation’s literature review.

Step 1. Create an Outline

If you’ve created a system for keeping track of the sources you’ve found, you likely already have the bones of an outline. Even if not, it may be relatively easy to see how to organize it all. The main thing to remember is, keep it simple and don’t overthink it. There are several ways to organize your dissertation’s literature review, and I’ll discuss some of the most common below:

• By topic. This is by far the most common approach, and it’s the one I recommend unless there’s a clear reason to do otherwise. Topics are things like servant leadership, transformational leadership, employee retention, organizational knowledge, etc. Organizing by topic is fairly simple and it makes sense to the reader.
• Chronologically. In some cases, it makes sense to tell the story of how knowledge and thought on a given subject have evolved. In this case, sub-sections may indicate important advances or contributions. 
• By methodology. Some students organize their literature review by the methodology of the studies. This makes sense when conducting a mixed-methods study, and in cases where methodology is at the forefront.

Step 2. Write the Paragraphs 

I said earlier that I thought the lit review was the easiest part to write, and here is why. When you write about the findings of others, you can do it in small, discrete time periods. You go down the path awhile, then you rest. 

Once you have many small pieces written, you can then piece them together. You can write each piece without worrying about the flow of the chapter; that can all be done at the end when you put the jigsaw puzzle of references together.

Step 3. Analyze

The literature review is a demonstration of your ability to think critically about existing research and build meaningfully on it in your study. Avoid simply stating what other researchers said. Find the relationships between studies, note where researchers agree and disagree, and– especiallyy–relate it to your own study. 

Pay special attention to controversial issues, and don’t be afraid to give space to researchers who you disagree with. Including differing opinions will only strengthen the credibility of your study, as it demonstrates that you’re willing to consider all sides.

Step 4. Justify the Methodology

In addition to discussing studies related to your topic, include some background on the methodology you will be using. This is especially important if you are using a new or little-used methodology, as it may help get committee members onboard. 

I have seen several students get slowed down in the process trying to get committees to buy into the planned methodology. Providing references and samples of where the planned methodology has been used makes the job of the committee easier, and it will also help your reader trust the outcomes.

Advice for Writing Your Dissertation’s Literature Review

• Remember to relate each section back to your study (your Problem and Purpose statements).
• Discuss conflicting findings or theoretical positions. Avoid the temptation to only include research that you agree with.
• Sections should flow together, the way sections of a chapter in a nonfiction book do. They should relate to each other and relate back to the purpose of your study. Avoid making each section an island.
• Discuss how each study or theory relates to the others in that section.
• Avoid relying on direct quotes–you should demonstrate that you understand the study and can describe it accurately.

Sample Outline of a Literature Review (Dissertation Chapter 2)

Here is a sample outline, with some brief instructions. Note that your institution probably has specific requirements for the structure of your dissertation’s literature review. But to give you a general idea, I’ve provided a sample outline of a dissertation ’s literature review here.

• Introduction
• State the problem and the purpose of the study
• Give a brief synopsis of literature that establishes the relevance of the problem
• Very briefly summarize the major sections of your chapter

Documentation of Literature Search Strategy

• Include the library databases and search engines you used
• List the key terms you used
• Describe the scope (qualitative) or iterative process (quantitative). Explain why and based on what criteria you selected the articles you did.

Literature Review (this is the meat of the chapter)

• Sub-topic a
• Sub-topic b
• Sub-topic c

See below for an example of what this outline might look like.

How to Write a Literature Review for a Dissertation: An Example 

Let’s take an example that will make the organization, and the outline, a little bit more clear. Below, I’ll fill out the example outline based on the topics discussed.

If your questions have to do with the impact of the servant leadership style of management on employee retention, you may want to saunter down the path of servant leadership first, learning of its origins , its principles , its values , and its methods . 

You’ll note the different ways the style is employed based on different practitioners’ perspectives or circumstances and how studies have evaluated these differences. Researchers will draw conclusions that you’ll want to note, and these conclusions will lead you to your next questions. 

Next, you’ll want to wander into the territory of management styles to discover their impact on employee retention in general. Does management style really make a difference in employee retention, and if so, what factors, exactly, make this impact?

Employee retention is its own path, and you’ll discover factors, internal and external, that encourage people to stick with their jobs.

You’ll likely find paradoxes and contradictions in here that just bring up more questions. How do internal and external factors mix and match? How can employers influence both psychology and context ? Is it of benefit to try and do so?

At first, these three paths seem somewhat remote from one another, but your interest is where the three converge. Taking the lit review section by section like this before tying it all together will not only make it more manageable to write but will help you lead your reader down the same path you traveled, thereby increasing clarity. 

Example Outline

So the main sections of your literature review might look something like this:

• Literature Search Strategy
• Conceptual Framework or Theoretical Foundation
• Literature that supports your methodology
• Origins, principles, values
• Seminal research
• Current research
• Management Styles’ Impact on employee retention
• Internal Factors
• External Factors
• Influencing psychology and context
• Summary and Conclusion

Final Thoughts on Writing Your Dissertation’s Chapter 2

The lit review provides the foundation for your study and perhaps for your career. Spend time reading and getting lost in the literature. The “aha” moments will come where you see how everything fits together. 

At that point, it will just be a matter of clearly recording and tracing your path, keeping your references organized, and conveying clearly how your research questions are a natural evolution of previous work that has been done.

Literature reviews

Writing a literature review.

The following guide has been created for you by the  Student Learning Advisory Service . For more detailed guidance and to speak to one of our advisers, please book an  appointment  or join one of our  workshops . Alternatively, have a look at our  SkillBuilder  skills videos.   

Preparing a literature review involves:

• Searching for reliable, accurate and up-to-date material on a topic or subject
• Reading and summarising the key points from this literature
• Synthesising these key ideas, theories and concepts into a summary of what is known
• Discussing and evaluating these ideas, theories and concepts
• Identifying particular areas of debate or controversy
• Preparing the ground for the application of these ideas to new research

Finding and choosing material

Ensure you are clear on what you are looking for. ask yourself:.

• What is the specific question, topic or focus of my assignment?
• What kind of material do I need (e.g. theory, policy, empirical data)?
• What type of literature is available (e.g. journals, books, government documents)?

What kind of literature is particularly authoritative in this academic discipline (e.g. psychology, sociology, pharmacy)?

How much do you need?

This will depend on the length of the dissertation, the nature of the subject, and the level of study (undergraduate, Masters, PhD). As a very rough rule of thumb – you may choose 8-10 significant pieces (books and/or articles) for an 8,000 word dissertation, up to 20 major pieces of work for 12-15,000 words, and so on. Bear in mind that if your dissertation is based mainly around an interaction with existing scholarship you will need a longer literature review than if it is there as a prelude to new empirical research. Use your judgement or ask your supervisor for guidance.

Where to find suitable material

Your literature review should include a balance between substantial academic books, journal articles and other scholarly publications. All these sources should be as up-to-date as possible, with the exception of ‘classic texts’ such as major works written by leading scholars setting out formative ideas and theories central to your subject. There are several ways to locate suitable material:

Module bibliography: for undergraduate dissertations, look first at the bibliography provided with the module documentation. Choose one or two likely looking books or articles and then scan through the bibliographies provided by these authors. Skim read some of this material looking for clues: can you use these leads to identify key theories and authors or track down other appropriate material?

Library catalogue search engine: enter a few key words to capture a range of items, but avoid over-generalisations; if you type in something as broad as ‘social theory’ you are likely to get several thousand results. Be more specific: for example, ‘Heidegger, existentialism’. Ideally, you should narrow the field to obtain just a few dozen results. Skim through these quickly to identity texts which are most likely to contribute to your study.

Library bookshelves: browse the library shelves in the relevant subject area and examine the books that catch your eye. Check the contents and index pages, or skim through the introductions (or abstracts, in the case of journal articles) to see if they contain relevant material, and replace them if not. Don’t be afraid to ask one of the subject librarians for further help. Your supervisor may also be able to point you in the direction of some of the important literature , but remember this is your literature search, not theirs.

Online: for recent journal articles you will almost certainly need to use one of the online search engines. These can be found on the ‘Indexing Services’ button on the Templeman Library website. Kent students based at Medway still need to use the Templeman pages to access online journals, although you can get to these pages through the Drill Hall Library catalogue. Take a look as well at the Subject Guides on both the Templeman and DHL websites.

Check that you have made the right selection by asking:

• Has my search been wide enough to ensure that I have identified all the relevant material, but narrow enough to exclude irrelevant material?
• Is there a good enough sample of literature for the level (PhD, Masters, undergraduate) of my dissertation or thesis?
• Have I considered as many alternative points of view as possible?
• Will the reader find my literature review relevant and useful?

Assessing the literature

Read the material you have chosen carefully, considering the following:

• The key point discussed by the author: is this clearly defined
• What evidence has the author produced to support this central idea?
• How convincing are the reasons given for the author’s point of view?
• Could the evidence be interpreted in other ways?
• What is the author's research method (e.g. qualitative, quantitative, experimental, etc.)?
• What is the author's theoretical framework (e.g. psychological, developmental, feminist)?
• What is the relationship assumed by the author between theory and practice?
• Has the author critically evaluated the other literature in the field?
• Does the author include literature opposing their point of view?
• Is the research data based on a reliable method and accurate information?
• Can you ‘deconstruct’ the argument – identify the gaps or jumps in the logic?
• What are the strengths and limitations of this study?
• What does this book or article contribute to the field or topic?
• What does this book or article contribute to my own topic or thesis?

As you note down the key content of each book or journal article (together with the reference details of each source) record your responses to these questions. You will then be able to summarise each piece of material from two perspectives:     

Content: a brief description of the content of the book or article. Remember, an author will often make just one key point; so, what is the point they are making, and how does it relate to your own research project or assignment?

Critical analysis: an assessment of the relative strengths and weaknesses of the evidence used, and the arguments presented. Has anything conveniently been left out or skated over? Is there a counter-argument, and has the author dealt with this adequately? Can the evidence presented be interpreted another way? Does the author demonstrate any obvious bias which could affect their reliability? Overall, based on the above analysis of the author’s work, how do you evaluate its contribution to the scholarly understanding and knowledge surrounding the topic?    

Structuring the literature review

In a PhD thesis, the literature review typically comprises one chapter (perhaps 8-10,000 words), for a Masters dissertation it may be around 2-3,000 words, and for an undergraduate dissertation it may be no more than 2,000 words. In each case the word count can vary depending on a range of factors and it is always best, if in doubt, to ask your supervisor.

The overall structure of the section or chapter should be like any other: it should have a beginning, middle and end. You will need to guide the reader through the literature review, outlining the strategy you have adopted for selecting the books or articles, presenting the topic theme for the review, then using most of the word limit to analyse the chosen books or articles thoroughly before pulling everything together briefly in the conclusion.

Some people prefer a less linear approach. Instead of simply working through a list of 8-20 items on your book review list, you might want to try a thematic approach, grouping key ideas, facts, concepts or approaches together and then bouncing the ideas off each other. This is a slightly more creative (and interesting) way of producing the review, but a little more risky as it is harder to establish coherence and logical sequencing.

Whichever approach you adopt, make sure everything flows smoothly – that one idea or book leads neatly to the next. Take your reader effortlessly through a sequence of thought that is clear, accurate, precise and interesting. 

Writing up your literature review

As with essays generally, only attempt to write up the literature review when you have completed all the reading and note-taking, and carefully planned its content and structure. Find an appropriate way of introducing the review, then guide the reader through the material clearly and directly, bearing in mind the following:

• Be selective in the number of points you draw out from each piece of literature; remember that one of your objectives is to demonstrate that you can use your judgement to identify what is central and what is secondary.
• Summarise and synthesise – use your own words to sum up what you think is important or controversial about the book or article.
• Never claim more than the evidence will support. Too many dissertations and theses are let down by sweeping generalisations. Be tentative and careful in the way you interpret the evidence.
• Keep your own voice – you are entitled to your own point of view provided it is based on evidence and clear argument.
• At the same time, aim to project an objective and tentative tone by using the 3rd person, (for example, ‘this tends to suggest’, ‘it could be argued’ and so on).
• Even with a literature review you should avoid using too many, or overlong, quotes. Summarise material in your own words as much as possible. Save the quotes for ‘punch-lines’ to drive a particular point home.
• Revise, revise, revise: refine and edit the draft as much as you can. Check for fluency, structure, evidence, criticality and referencing, and don’t forget the basics of good grammar, punctuation and spelling.

• What Is a PhD Literature Review?
• Doing a PhD

A literature review is a critical analysis of published academic literature, mainly peer-reviewed papers and books, on a specific topic. This isn’t just a list of published studies but is a document summarising and critically appraising the main work by researchers in the field, the key findings, limitations and gaps identified in the knowledge.

• The aim of a literature review is to critically assess the literature in your chosen field of research and be able to present an overview of the current knowledge gained from previous work.
• By the conclusion of your literature review, you as a researcher should have identified the gaps in knowledge in your field; i.e. the unanswered research questions which your PhD project will help to answer.
• Quality not quantity is the approach to use when writing a literature review for a PhD but as a general rule of thumb, most are between 6,000 and 12,000 words.

What Is the Purpose of a Literature Review?

First, to be clear on what a PhD literature review is NOT: it is not a ‘paper by paper’ summary of what others have done in your field. All you’re doing here is listing out all the papers and book chapters you’ve found with some text joining things together. This is a common mistake made by PhD students early on in their research project. This is a sign of poor academic writing and if it’s not picked up by your supervisor, it’ll definitely be by your examiners.

The biggest issue your examiners will have here is that you won’t have demonstrated an application of critical thinking when examining existing knowledge from previous research. This is an important part of the research process as a PhD student. It’s needed to show where the gaps in knowledge were, and how then you were able to identify the novelty of each research question and subsequent work.

The five main outcomes from carrying out a good literature review should be:

• An understanding of what has been published in your subject area of research,
• An appreciation of the leading research groups and authors in your field and their key contributions to the research topic,
• Knowledge of the key theories in your field,
• Knowledge of the main research areas within your field of interest,
• A clear understanding of the research gap in knowledge that will help to motivate your PhD research questions .

When assessing the academic papers or books that you’ve come across, you must think about the strengths and weaknesses of them; what was novel about their work and what were the limitations? Are different sources of relevant literature coming to similar conclusions and complementing each other, or are you seeing different outcomes on the same topic by different researchers?

When Should I Write My Literature Review?

In the structure of your PhD thesis , your literature review is effectively your first main chapter. It’s at the start of your thesis and should, therefore, be a task you perform at the start of your research. After all, you need to have reviewed the literature to work out how your research can contribute novel findings to your area of research. Sometimes, however, in particular when you apply for a PhD project with a pre-defined research title and research questions, your supervisor may already know where the gaps in knowledge are.

You may be tempted to skip the literature review and dive straight into tackling the set questions (then completing the review at the end before thesis submission) but we strongly advise against this. Whilst your supervisor will be very familiar with the area, you as a doctoral student will not be and so it is essential that you gain this understanding before getting into the research.

How Long Should the Literature Review Be?

As your literature review will be one of your main thesis chapters, it needs to be a substantial body of work. It’s not a good strategy to have a thesis writing process here based on a specific word count, but know that most reviews are typically between 6,000 and 12,000 words. The length will depend on how much relevant material has previously been published in your field.

A point to remember though is that the review needs to be easy to read and avoid being filled with unnecessary information; in your search of selected literature, consider filtering out publications that don’t appear to add anything novel to the discussion – this might be useful in fields with hundreds of papers.

How Do I Write the Literature Review?

Before you start writing your literature review, you need to be clear on the topic you are researching.

1. Evaluating and Selecting the Publications

After completing your literature search and downloading all the papers you find, you may find that you have a lot of papers to read through ! You may find that you have so many papers that it’s unreasonable to read through all of them in their entirety, so you need to find a way to understand what they’re about and decide if they’re important quickly.

A good starting point is to read the abstract of the paper to gauge if it is useful and, as you do so, consider the following questions in your mind:

• What was the overarching aim of the paper?
• What was the methodology used by the authors?
• Was this an experimental study or was this more theoretical in its approach?
• What were the results and what did the authors conclude in their paper?
• How does the data presented in this paper relate to other publications within this field?
• Does it add new knowledge, does it raise more questions or does it confirm what is already known in your field? What is the key concept that the study described?
• What are the strengths and weaknesses of this study, and in particular, what are the limitations?

2. Identifying Themes

To put together the structure of your literature review you need to identify the common themes that emerge from the collective papers and books that you have read. Key things to think about are:

• Are there common methodologies different authors have used or have these changed over time?
• Do the research questions change over time or are the key question’s still unanswered?
• Is there general agreement between different research groups in the main results and outcomes, or do different authors provide differing points of view and different conclusions?
• What are the key papers in your field that have had the biggest impact on the research?
• Have different publications identified similar weaknesses or limitations or gaps in the knowledge that still need to be addressed?

Structuring and Writing Your Literature Review

There are several ways in which you can structure a literature review and this may depend on if, for example, your project is a science or non-science based PhD.

One approach may be to tell a story about how your research area has developed over time. You need to be careful here that you don’t just describe the different papers published in chronological order but that you discuss how different studies have motivated subsequent studies, how the knowledge has developed over time in your field, concluding with what is currently known, and what is currently not understood.

Alternatively, you may find from reading your papers that common themes emerge and it may be easier to develop your review around these, i.e. a thematic review. For example, if you are writing up about bridge design, you may structure the review around the themes of regulation, analysis, and sustainability.

As another approach, you might want to talk about the different research methodologies that have been used. You could then compare and contrast the results and ultimate conclusions that have been drawn from each.

As with all your chapters in your thesis, your literature review will be broken up into three key headings, with the basic structure being the introduction, the main body and conclusion. Within the main body, you will use several subheadings to separate out the topics depending on if you’re structuring it by the time period, the methods used or the common themes that have emerged.

The important thing to think about as you write your main body of text is to summarise the key takeaway messages from each research paper and how they come together to give one or more conclusions. Don’t just stop at summarising the papers though, instead continue on to give your analysis and your opinion on how these previous publications fit into the wider research field and where they have an impact. Emphasise the strengths of the studies you have evaluated also be clear on the limitations of previous work how these may have influenced the results and conclusions of the studies.

In your concluding paragraphs focus your discussion on how your critical evaluation of literature has helped you identify unanswered research questions and how you plan to address these in your PhD project. State the research problem you’re going to address and end with the overarching aim and key objectives of your work .

When writing at a graduate level, you have to take a critical approach when reading existing literature in your field to determine if and how it added value to existing knowledge. You may find that a large number of the papers on your reference list have the right academic context but are essentially saying the same thing. As a graduate student, you’ll need to take a methodological approach to work through this existing research to identify what is relevant literature and what is not.

You then need to go one step further to interpret and articulate the current state of what is known, based on existing theories, and where the research gaps are. It is these gaps in the literature that you will address in your own research project.

• Decide on a research area and an associated research question.
• Decide on the extent of your scope and start looking for literature.
• Review and evaluate the literature.
• Plan an outline for your literature review and start writing it.

Review of Related Literature (RRL) 1. Introduction This review examines research on social media’s impact on mental health, focusing on anxiety and depression across various demographics over the past ten years. 2. Theoretical Framework Anchored in Social Comparison Theory and Uses and Gratifications Theory, this review explores how individuals’ social media interactions affect their mental health. 3. Review of Empirical Studies Adolescents’ Mental Health Instagram & Body Image : Smith & Johnson (2017) found Instagram use linked to body image issues and lower self-esteem among 500 high school students. Facebook & Anxiety : Brown & Green (2016) showed Facebook use correlated with higher anxiety and depressive symptoms in a longitudinal study of 300 students. Young Adults’ Mental Health Twitter & Stress : Davis & Lee (2018) reported higher stress levels among heavy Twitter users in a survey of 400 university students. LinkedIn & Self-Esteem : Miller & White (2019) found LinkedIn use positively influenced professional self-esteem in 200 young professionals. Adult Mental Health General Social Media Use : Thompson & Evans (2020) found moderate social media use associated with better mental health outcomes, while excessive use correlated with higher anxiety and depression in 1,000 adults. 4. Methodological Review Studies used cross-sectional surveys, longitudinal designs, and mixed methods. Cross-sectional surveys provided large data sets but couldn’t infer causation. Longitudinal studies offered insights into long-term effects but were resource-intensive. Mixed methods enriched data through qualitative insights but required careful integration. 5. Synthesis and Critique The literature shows a complex relationship between social media and mental health, with platform-specific and demographic-specific effects. However, reliance on self-reported data introduces bias, and many cross-sectional studies limit causal inference. More longitudinal and experimental research is needed. 6. Conclusion Current research offers insights into social media’s mental health impact but leaves gaps, particularly regarding long-term effects and causation. This study aims to address these gaps through comprehensive longitudinal analysis. 7. References Brown, A., & Green, K. (2016). Facebook Use and Anxiety Among High School Students .
