Nursing: How to Write a Literature Review

• Traditional or Narrative Literature Review

Getting started

1. start with your research question, 2. search the literature, 3. read & evaluate, 4. finalize results, 5. write & revise, brainfuse online tutoring and writing review.

• RESEARCH HELP

The best way to approach your literature review is to break it down into steps.  Remember, research is an iterative process, not a linear one.  You will revisit steps and revise along the way.  Get started with the handout, information, and tips from various university Writing Centers below that provides an excellent overview.  Then move on to the specific steps recommended on this page.

• UNC- Chapel Hill Writing Center Literature Review Handout, from the University of North Carolina at Chapel Hill.
• University of Wisconsin-Madison Writing Center Learn how to write a review of literature, from the University of Wisconsin-Madison.
• University of Toronto-- Writing Advice The Literature Review: A few tips on conducting it, from the University of Toronto.
• Begin with a topic.
• Understand the topic. 
• Familiarize yourself with the terminology.  Note what words are being used and keep track of these for use as database search keywords. 
• See what research has been done on this topic before you commit to the topic.  Review articles can be helpful to understand what research has been done .
• Develop your research question.  (see handout below)
• How comprehensive should it be? 
• Is it for a course assignment or a dissertation? 
• How many years should it cover?
• Developing a good nursing research question Handout. Reviews PICO method and provides search tips.

Your next step is to construct a search strategy and then locate & retrieve articles.

•  There are often 2-4 key concepts in a research question.
• Search for primary sources (original research articles.)
• These are based on the key concepts in your research question.
• Remember to consider synonyms and related terms.
• Which databases to search?
• What limiters should be applied (peer-reviewed, publication date, geographic location, etc.)?

Review articles (secondary sources)

Use to identify literature on your topic, the way you would use a bibliography.  Then locate and retrieve the original studies discussed in the review article. Review articles are considered secondary sources.

• Once you have some relevant articles, review reference lists to see if there are any useful articles.
• Which articles were written later and have cited some of your useful articles?  Are these, in turn, articles that will be useful to you? 
• Keep track of what terms you used and what databases you searched. 
• Use database tools such as save search history in EBSCO to help.
• Keep track of the citations for the articles you will be using in your literature review. 
• Use RefWorks or another method of tracking this information. 
• Database Search Strategy Worksheet Handout. How to construct a search.
• TUTORIAL: How to do a search based on your research question This is a self-paced, interactive tutorial that reviews how to construct and perform a database search in CINAHL.

The next step is to read, review, and understand the articles.

• Start by reviewing abstracts. 
• Make sure you are selecting primary sources (original research articles).
• Note any keywords authors report using when searching for prior studies.
• You will need to evaluate and critique them and write a synthesis related to your research question.
• Consider using a matrix to organize and compare and contrast the articles . 
• Which authors are conducting research in this area?  Search by author.  
• Are there certain authors’ whose work is cited in many of your articles?  Did they write an early, seminal article that is often cited?
• Searching is a cyclical process where you will run searches, review results, modify searches, run again, review again, etc. 
• Critique articles.  Keep or exclude based on whether they are relevant to your research question.
• When you have done a thorough search using several databases plus Google Scholar, using appropriate keywords or subject terms, plus author’s names, and you begin to find the same articles over and over.
• Remember to consider the scope of your project and the length of your paper.  A dissertation will have a more exhaustive literature review than an 8 page paper, for example.
• What are common findings among each group or where do they disagree? 
• Identify common themes. Identify controversial or problematic areas in the research. 
• Use your matrix to organize this.
• Once you have read and re-read your articles and organized your findings, you are ready to begin the process of writing the literature review.

2. Synthesize.  (see handout below)

• Include a synthesis of the articles you have chosen for your literature review.
• A literature review is NOT a list or a summary of what has been written on a particular topic. 
• It analyzes the articles in terms of how they relate to your research question. 
• While reading, look for similarities and differences (compare and contrast) among the articles.  You will create your synthesis from this.
• Synthesis Examples Handout. Sample excerpts that illustrate synthesis.

What is a Literature Review? | Guide, Template, & Examples

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.

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 .

The Scholarly Conversation

A literature review provides an overview of previous research on a topic that critically evaluates, classifies, and compares what has already been published on a particular topic. It allows the author to synthesize and place into context the research and scholarly literature relevant to the topic. It helps map the different approaches to a given question and reveals patterns. It forms the foundation for the author’s subsequent research and justifies the significance of the new investigation.

A literature review can be a short introductory section of a research article or a report or policy paper that focuses on recent research. Or, in the case of dissertations, theses, and review articles, it can be an extensive review of all relevant research.

• The format is usually a bibliographic essay; sources are briefly cited within the body of the essay, with full bibliographic citations at the end.
• The introduction should define the topic and set the context for the literature review. It will include the author's perspective or point of view on the topic, how they have defined the scope of the topic (including what's not included), and how the review will be organized. It can point out overall trends, conflicts in methodology or conclusions, and gaps in the research.
• In the body of the review, the author should organize the research into major topics and subtopics. These groupings may be by subject, (e.g., globalization of clothing manufacturing), type of research (e.g., case studies), methodology (e.g., qualitative), genre, chronology, or other common characteristics. Within these groups, the author can then discuss the merits of each article and analyze and compare the importance of each article to similar ones.
• The conclusion will summarize the main findings, make clear how this review of the literature supports (or not) the research to follow, and may point the direction for further research.
• The list of references will include full citations for all of the items mentioned in the literature review.

A literature review should try to answer questions such as

• Who are the key researchers on this topic?
• What has been the focus of the research efforts so far and what is the current status?
• How have certain studies built on prior studies? Where are the connections? Are there new interpretations of the research?
• Have there been any controversies or debate about the research? Is there consensus? Are there any contradictions?
• Which areas have been identified as needing further research? Have any pathways been suggested?
• How will your topic uniquely contribute to this body of knowledge?
• Which methodologies have researchers used and which appear to be the most productive?
• What sources of information or data were identified that might be useful to you?
• How does your particular topic fit into the larger context of what has already been done?
• How has the research that has already been done help frame your current investigation ?

How To Write An A-Grade Literature Review

3 straightforward steps (with examples) + free template.

By: Derek Jansen (MBA) | Expert Reviewed By: Dr. Eunice Rautenbach | October 2019

Quality research is about building onto the existing work of others , “standing on the shoulders of giants”, as Newton put it. The literature review chapter of your dissertation, thesis or research project is where you synthesise this prior work and lay the theoretical foundation for your own research.

Long story short, this chapter is a pretty big deal, which is why you want to make sure you get it right . In this post, I’ll show you exactly how to write a literature review in three straightforward steps, so you can conquer this vital chapter (the smart way).

Overview: The Literature Review Process

• Understanding the “ why “
• Finding the relevant literature
• Cataloguing and synthesising the information
• Outlining & writing up your literature review
• Example of a literature review

But first, the “why”…

Before we unpack how to write the literature review chapter, we’ve got to look at the why . To put it bluntly, if you don’t understand the function and purpose of the literature review process, there’s no way you can pull it off well. So, what exactly is the purpose of the literature review?

Well, there are (at least) four core functions:

• For you to gain an understanding (and demonstrate this understanding) of where the research is at currently, what the key arguments and disagreements are.
• For you to identify the gap(s) in the literature and then use this as justification for your own research topic.
• To help you build a conceptual framework for empirical testing (if applicable to your research topic).
• To inform your methodological choices and help you source tried and tested questionnaires (for interviews ) and measurement instruments (for surveys ).

Most students understand the first point but don’t give any thought to the rest. To get the most from the literature review process, you must keep all four points front of mind as you review the literature (more on this shortly), or you’ll land up with a wonky foundation.

Okay – with the why out the way, let’s move on to the how . As mentioned above, writing your literature review is a process, which I’ll break down into three steps:

• Finding the most suitable literature
• Understanding , distilling and organising the literature
• Planning and writing up your literature review chapter

Importantly, you must complete steps one and two before you start writing up your chapter. I know it’s very tempting, but don’t try to kill two birds with one stone and write as you read. You’ll invariably end up wasting huge amounts of time re-writing and re-shaping, or you’ll just land up with a disjointed, hard-to-digest mess . Instead, you need to read first and distil the information, then plan and execute the writing.

Step 1: Find the relevant literature

Naturally, the first step in the literature review journey is to hunt down the existing research that’s relevant to your topic. While you probably already have a decent base of this from your research proposal , you need to expand on this substantially in the dissertation or thesis itself.

Essentially, you need to be looking for any existing literature that potentially helps you answer your research question (or develop it, if that’s not yet pinned down). There are numerous ways to find relevant literature, but I’ll cover my top four tactics here. I’d suggest combining all four methods to ensure that nothing slips past you:

Method 1 – Google Scholar Scrubbing

Google’s academic search engine, Google Scholar , is a great starting point as it provides a good high-level view of the relevant journal articles for whatever keyword you throw at it. Most valuably, it tells you how many times each article has been cited, which gives you an idea of how credible (or at least, popular) it is. Some articles will be free to access, while others will require an account, which brings us to the next method.

Method 2 – University Database Scrounging

Generally, universities provide students with access to an online library, which provides access to many (but not all) of the major journals.

So, if you find an article using Google Scholar that requires paid access (which is quite likely), search for that article in your university’s database – if it’s listed there, you’ll have access. Note that, generally, the search engine capabilities of these databases are poor, so make sure you search for the exact article name, or you might not find it.

Method 3 – Journal Article Snowballing

At the end of every academic journal article, you’ll find a list of references. As with any academic writing, these references are the building blocks of the article, so if the article is relevant to your topic, there’s a good chance a portion of the referenced works will be too. Do a quick scan of the titles and see what seems relevant, then search for the relevant ones in your university’s database.

Method 4 – Dissertation Scavenging

Similar to Method 3 above, you can leverage other students’ dissertations. All you have to do is skim through literature review chapters of existing dissertations related to your topic and you’ll find a gold mine of potential literature. Usually, your university will provide you with access to previous students’ dissertations, but you can also find a much larger selection in the following databases:

• Open Access Theses & Dissertations
• Stanford SearchWorks

Keep in mind that dissertations and theses are not as academically sound as published, peer-reviewed journal articles (because they’re written by students, not professionals), so be sure to check the credibility of any sources you find using this method. You can do this by assessing the citation count of any given article in Google Scholar. If you need help with assessing the credibility of any article, or with finding relevant research in general, you can chat with one of our Research Specialists .

Alright – with a good base of literature firmly under your belt, it’s time to move onto the next step.

Step 2: Log, catalogue and synthesise

Once you’ve built a little treasure trove of articles, it’s time to get reading and start digesting the information – what does it all mean?

While I present steps one and two (hunting and digesting) as sequential, in reality, it’s more of a back-and-forth tango – you’ll read a little , then have an idea, spot a new citation, or a new potential variable, and then go back to searching for articles. This is perfectly natural – through the reading process, your thoughts will develop , new avenues might crop up, and directional adjustments might arise. This is, after all, one of the main purposes of the literature review process (i.e. to familiarise yourself with the current state of research in your field).

As you’re working through your treasure chest, it’s essential that you simultaneously start organising the information. There are three aspects to this:

• Logging reference information
• Building an organised catalogue
• Distilling and synthesising the information

I’ll discuss each of these below:

2.1 – Log the reference information

As you read each article, you should add it to your reference management software. I usually recommend Mendeley for this purpose (see the Mendeley 101 video below), but you can use whichever software you’re comfortable with. Most importantly, make sure you load EVERY article you read into your reference manager, even if it doesn’t seem very relevant at the time.

2.2 – Build an organised catalogue

In the beginning, you might feel confident that you can remember who said what, where, and what their main arguments were. Trust me, you won’t. If you do a thorough review of the relevant literature (as you must!), you’re going to read many, many articles, and it’s simply impossible to remember who said what, when, and in what context . Also, without the bird’s eye view that a catalogue provides, you’ll miss connections between various articles, and have no view of how the research developed over time. Simply put, it’s essential to build your own catalogue of the literature.

I would suggest using Excel to build your catalogue, as it allows you to run filters, colour code and sort – all very useful when your list grows large (which it will). How you lay your spreadsheet out is up to you, but I’d suggest you have the following columns (at minimum):

• Author, date, title – Start with three columns containing this core information. This will make it easy for you to search for titles with certain words, order research by date, or group by author.
• Categories or keywords – You can either create multiple columns, one for each category/theme and then tick the relevant categories, or you can have one column with keywords.
• Key arguments/points – Use this column to succinctly convey the essence of the article, the key arguments and implications thereof for your research.
• Context – Note the socioeconomic context in which the research was undertaken. For example, US-based, respondents aged 25-35, lower- income, etc. This will be useful for making an argument about gaps in the research.
• Methodology – Note which methodology was used and why. Also, note any issues you feel arise due to the methodology. Again, you can use this to make an argument about gaps in the research.
• Quotations – Note down any quoteworthy lines you feel might be useful later.
• Notes – Make notes about anything not already covered. For example, linkages to or disagreements with other theories, questions raised but unanswered, shortcomings or limitations, and so forth.

If you’d like, you can try out our free catalog template here (see screenshot below).

2.3 – Digest and synthesise

Most importantly, as you work through the literature and build your catalogue, you need to synthesise all the information in your own mind – how does it all fit together? Look for links between the various articles and try to develop a bigger picture view of the state of the research. Some important questions to ask yourself are:

• What answers does the existing research provide to my own research questions ?
• Which points do the researchers agree (and disagree) on?
• How has the research developed over time?
• Where do the gaps in the current research lie?

To help you develop a big-picture view and synthesise all the information, you might find mind mapping software such as Freemind useful. Alternatively, if you’re a fan of physical note-taking, investing in a large whiteboard might work for you.

Step 3: Outline and write it up!

Once you’re satisfied that you have digested and distilled all the relevant literature in your mind, it’s time to put pen to paper (or rather, fingers to keyboard). There are two steps here – outlining and writing:

3.1 – Draw up your outline

Having spent so much time reading, it might be tempting to just start writing up without a clear structure in mind. However, it’s critically important to decide on your structure and develop a detailed outline before you write anything. Your literature review chapter needs to present a clear, logical and an easy to follow narrative – and that requires some planning. Don’t try to wing it!

Naturally, you won’t always follow the plan to the letter, but without a detailed outline, you’re more than likely going to end up with a disjointed pile of waffle , and then you’re going to spend a far greater amount of time re-writing, hacking and patching. The adage, “measure twice, cut once” is very suitable here.

In terms of structure, the first decision you’ll have to make is whether you’ll lay out your review thematically (into themes) or chronologically (by date/period). The right choice depends on your topic, research objectives and research questions, which we discuss in this article .

Once that’s decided, you need to draw up an outline of your entire chapter in bullet point format. Try to get as detailed as possible, so that you know exactly what you’ll cover where, how each section will connect to the next, and how your entire argument will develop throughout the chapter. Also, at this stage, it’s a good idea to allocate rough word count limits for each section, so that you can identify word count problems before you’ve spent weeks or months writing!

3.2 – Get writing

With a detailed outline at your side, it’s time to start writing up (finally!). At this stage, it’s common to feel a bit of writer’s block and find yourself procrastinating under the pressure of finally having to put something on paper. To help with this, remember that the objective of the first draft is not perfection – it’s simply to get your thoughts out of your head and onto paper, after which you can refine them. The structure might change a little, the word count allocations might shift and shuffle, and you might add or remove a section – that’s all okay. Don’t worry about all this on your first draft – just get your thoughts down on paper.

Once you’ve got a full first draft (however rough it may be), step away from it for a day or two (longer if you can) and then come back at it with fresh eyes. Pay particular attention to the flow and narrative – does it fall fit together and flow from one section to another smoothly? Now’s the time to try to improve the linkage from each section to the next, tighten up the writing to be more concise, trim down word count and sand it down into a more digestible read.

Once you’ve done that, give your writing to a friend or colleague who is not a subject matter expert and ask them if they understand the overall discussion. The best way to assess this is to ask them to explain the chapter back to you. This technique will give you a strong indication of which points were clearly communicated and which weren’t. If you’re working with Grad Coach, this is a good time to have your Research Specialist review your chapter.

Finally, tighten it up and send it off to your supervisor for comment. Some might argue that you should be sending your work to your supervisor sooner than this (indeed your university might formally require this), but in my experience, supervisors are extremely short on time (and often patience), so, the more refined your chapter is, the less time they’ll waste on addressing basic issues (which you know about already) and the more time they’ll spend on valuable feedback that will increase your mark-earning potential.

Literature Review Example

In the video below, we unpack an actual literature review so that you can see how all the core components come together in reality.

Let’s Recap

In this post, we’ve covered how to research and write up a high-quality literature review chapter. Let’s do a quick recap of the key takeaways:

• It is essential to understand the WHY of the literature review before you read or write anything. Make sure you understand the 4 core functions of the process.
• The first step is to hunt down the relevant literature . You can do this using Google Scholar, your university database, the snowballing technique and by reviewing other dissertations and theses.
• Next, you need to log all the articles in your reference manager , build your own catalogue of literature and synthesise all the research.
• Following that, you need to develop a detailed outline of your entire chapter – the more detail the better. Don’t start writing without a clear outline (on paper, not in your head!)
• Write up your first draft in rough form – don’t aim for perfection. Remember, done beats perfect.
• Refine your second draft and get a layman’s perspective on it . Then tighten it up and submit it to your supervisor.

Psst… there’s more!

Literature Review Overview

What is a Literature Review? Why Are They Important?

A literature review is important because it presents the "state of the science" or accumulated knowledge on a specific topic. It summarizes, analyzes, and compares the available research, reporting study strengths and weaknesses, results, gaps in the research, conclusions, and authors’ interpretations.

Tips and techniques for conducting a literature review are described more fully in the subsequent boxes:

• Literature review steps
• Strategies for organizing the information for your review
• Literature reviews sections
• In-depth resources to assist in writing a literature review
• Templates to start your review

Literature Review Steps

Graphic used with permission: Torres, E. Librarian, Hawai'i Pacific University

1. Choose a topic and define your research question

• Try to choose a topic of interest. You will be working with this subject for several weeks to months.
• Ideas for topics can be found by scanning medical news sources (e.g MedPage Today), journals / magazines, work experiences, interesting patient cases, or family or personal health issues.
• Do a bit of background reading on topic ideas to familiarize yourself with terminology and issues. Note the words and terms that are used.
• Develop a focused research question using PICO(T) or other framework (FINER, SPICE, etc - there are many options) to help guide you.
• Run a few sample database searches to make sure your research question is not too broad or too narrow.
• If possible, discuss your topic with your professor. 

2. Determine the scope of your review

The scope of your review will be determined by your professor during your program. Check your assignment requirements for parameters for the Literature Review.

• How many studies will you need to include?
• How many years should it cover? (usually 5-7 depending on the professor)
• For the nurses, are you required to limit to nursing literature?

3. Develop a search plan

• Determine which databases to search. This will depend on your topic. If you are not sure, check your program specific library website (Physician Asst / Nursing / Health Services Admin) for recommendations.
• Create an initial search string using the main concepts from your research (PICO, etc) question. Include synonyms and related words connected by Boolean operators
• Contact your librarian for assistance, if needed.

4. Conduct searches and find relevant literature

• Keep notes as you search - tracking keywords and search strings used in each database in order to avoid wasting time duplicating a search that has already been tried
• Read abstracts and write down new terms to search as you find them
• Check MeSH or other subject headings listed in relevant articles for additional search terms
• Scan author provided keywords if available
• Check the references of relevant articles looking for other useful articles (ancestry searching)
• Check articles that have cited your relevant article for more useful articles (descendancy searching). Both PubMed and CINAHL offer Cited By links
• Revise the search to broaden or narrow your topic focus as you peruse the available literature
• Conducting a literature search is a repetitive process. Searches can be revised and re-run multiple times during the process.
• Track the citations for your relevant articles in a software citation manager such as RefWorks, Zotero, or Mendeley

5. Review the literature

• Read the full articles. Do not rely solely on the abstracts. Authors frequently cannot include all results within the confines of an abstract. Exclude articles that do not address your research question.
• While reading, note research findings relevant to your project and summarize. Are the findings conflicting? There are matrices available than can help with organization. See the Organizing Information box below.
• Critique / evaluate the quality of the articles, and record your findings in your matrix or summary table. Tools are available to prompt you what to look for. (See Resources for Appraising a Research Study box on the HSA, Nursing , and PA guides )
• You may need to revise your search and re-run it based on your findings.

6. Organize and synthesize

• Compile the findings and analysis from each resource into a single narrative.
• Using an outline can be helpful. Start broad, addressing the overall findings and then narrow, discussing each resource and how it relates to your question and to the other resources.
• Cite as you write to keep sources organized.
• Write in structured paragraphs using topic sentences and transition words to draw connections, comparisons, and contrasts.
• Don't present one study after another, but rather relate one study's findings to another. Speak to how the studies are connected and how they relate to your work.

Organizing Information

Options to assist in organizing sources and information :

1. Synthesis Matrix

• helps provide overview of the literature
• information from individual sources is entered into a grid to enable writers to discern patterns and themes
• article summary, analysis, or results
• thoughts, reflections, or issues
• each reference gets its own row
• mind maps, concept maps, flowcharts
• at top of page record PICO or research question
• record major concepts / themes from literature
• list concepts that branch out from major concepts underneath - keep going downward hierarchically, until most specific ideas are recorded
• enclose concepts in circles and connect the concept with lines - add brief explanation as needed

3. Summary Table

• information is recorded in a grid to help with recall and sorting information when writing
• allows comparing and contrasting individual studies easily
• purpose of study
• methodology (study population, data collection tool)

Efron, S. E., & Ravid, R. (2019). Writing the literature review : A practical guide . Guilford Press.

Literature Review Sections

• Lit reviews can be part of a larger paper / research study or they can be the focus of the paper
• Lit reviews focus on research studies to provide evidence
• New topics may not have much that has been published

* The sections included may depend on the purpose of the literature review (standalone paper or section within a research paper)

Standalone Literature Review (aka Narrative Review):

• presents your topic or PICO question
• includes the why of the literature review and your goals for the review.
• provides background for your the topic and previews the key points
• Narrative Reviews: tmay not have an explanation of methods.
• include where the search was conducted (which databases) what subject terms or keywords were used, and any limits or filters that were applied and why - this will help others re-create the search
• describe how studies were analyzed for inclusion or exclusion
• review the purpose and answer the research question
• thematically - using recurring themes in the literature
• chronologically - present the development of the topic over time
• methodological - compare and contrast findings based on various methodologies used to research the topic (e.g. qualitative vs quantitative, etc.)
• theoretical - organized content based on various theories
• provide an overview of the main points of each source then synthesize the findings into a coherent summary of the whole
• present common themes among the studies
• compare and contrast the various study results
• interpret the results and address the implications of the findings
• do the results support the original hypothesis or conflict with it
• provide your own analysis and interpretation (eg. discuss the significance of findings; evaluate the strengths and weaknesses of the studies, noting any problems)
• discuss common and unusual patterns and offer explanations
•  stay away from opinions, personal biases and unsupported recommendations
• summarize the key findings and relate them back to your PICO/research question
• note gaps in the research and suggest areas for further research
• this section should not contain "new" information that had not been previously discussed in one of the sections above
• provide a list of all the studies and other sources used in proper APA 7

Literature Review as Part of a Research Study Manuscript:

• Compares the study with other research and includes how a study fills a gap in the research.
• Focus on the body of the review which includes the synthesized Findings and Discussion

Literature Reviews vs Systematic Reviews

Systematic Reviews are NOT the same as a Literature Review:

Literature Reviews:

• Literature reviews may or may not follow strict systematic methods to find, select, and analyze articles, but rather they selectively and broadly review the literature on a topic
• Research included in a Literature Review can be "cherry-picked" and therefore, can be very subjective

Systematic Reviews:

• Systemic reviews are designed to provide a comprehensive summary of the evidence for a focused research question
• rigorous and strictly structured, using standardized reporting guidelines (e.g. PRISMA, see link below)
• uses exhaustive, systematic searches of all relevant databases
• best practice dictates search strategies are peer reviewed
• uses predetermined study inclusion and exclusion criteria in order to minimize bias
• aims to capture and synthesize all literature (including unpublished research - grey literature) that meet the predefined criteria on a focused topic resulting in high quality evidence

Literature Review Examples

• Breastfeeding initiation and support: A literature review of what women value and the impact of early discharge (2017). Women and Birth : Journal of the Australian College of Midwives
• Community-based participatory research to promote healthy diet and nutrition and prevent and control obesity among African-Americans: A literature review (2017). Journal of Racial and Ethnic Health Disparities

Writing a Literature Review

Tools to Help Organize your Literature Review

• APA Style and Reference Managers
• Evaluating Research Articles
• DNP Course Reserves

Unless you have a reason to present the literature chronologically (to show development over time, perhaps), the preferred method for organizing your literature is thematically. 

Step 1 : Identify your themes.

Step 2 : Identify the articles that address those themes

Step 3 : Identify the similarities and differences among the articles within the themes

A Literature Synthesis Matrix will be especially helpful in this process.

Literature Review Matrix

This type of matrix will help you see the content of all of your articles at a glance. Each row represents an article, and each column and element of the articles. Typical columns can include things like 

• Research method
• Sample size
• Theoretical framework

However, the exact columns you chose depend on the elements of each study you want to discuss in your paper. You get to decide!

Here are couple of examples to give you a better idea.

• An evolutionary concept analysis of helicopter parenting. (Lee et al., 2014)
• The use of video conferencing for persons with chronic conditions: A systematic review. (Mallow et al. 2016)

Literature Synthesis Matrix

In essence a synthesis matrix is a way to organize your literature by theme, which is generally the way writers organize their whole literature reviews. The real benefit is that it helps you identify the articles that talk about the same themes so that you can write about them together in your literature review.

North Carolina State  has a very nice description and example of the process. 

This YouTube video also explains the process.

Here is a  template  you can use (this one is in Word instead of PPT).

Implementing evidence into practice requires nurses to identify, critically appraise and synthesise research. This may require a comprehensive literature review: this article aims to outline the approaches and stages required and provides a working example of a published review.

Are there different approaches to undertaking a literature review?

What stages are required to undertake a literature review.

The rationale for the review should be established; consider why the review is important and relevant to patient care/safety or service delivery. For example, Noble et al 's 4 review sought to understand and make recommendations for practice and research in relation to dialysis refusal and withdrawal in patients with end-stage renal disease, an area of care previously poorly described. If appropriate, highlight relevant policies and theoretical perspectives that might guide the review. Once the key issues related to the topic, including the challenges encountered in clinical practice, have been identified formulate a clear question, and/or develop an aim and specific objectives. The type of review undertaken is influenced by the purpose of the review and resources available. However, the stages or methods used to undertake a review are similar across approaches and include:

Formulating clear inclusion and exclusion criteria, for example, patient groups, ages, conditions/treatments, sources of evidence/research designs;

Justifying data bases and years searched, and whether strategies including hand searching of journals, conference proceedings and research not indexed in data bases (grey literature) will be undertaken;

Developing search terms, the PICU (P: patient, problem or population; I: intervention; C: comparison; O: outcome) framework is a useful guide when developing search terms;

Developing search skills (eg, understanding Boolean Operators, in particular the use of AND/OR) and knowledge of how data bases index topics (eg, MeSH headings). Working with a librarian experienced in undertaking health searches is invaluable when developing a search.

Once studies are selected, the quality of the research/evidence requires evaluation. Using a quality appraisal tool, such as the Critical Appraisal Skills Programme (CASP) tools, 5 results in a structured approach to assessing the rigour of studies being reviewed. 3 Approaches to data synthesis for quantitative studies may include a meta-analysis (statistical analysis of data from multiple studies of similar designs that have addressed the same question), or findings can be reported descriptively. 6 Methods applicable for synthesising qualitative studies include meta-ethnography (themes and concepts from different studies are explored and brought together using approaches similar to qualitative data analysis methods), narrative summary, thematic analysis and content analysis. 7 Table 1 outlines the stages undertaken for a published review that summarised research about parents’ experiences of living with a child with a long-term condition. 8

An example of rapid evidence assessment review

In summary, the type of literature review depends on the review purpose. For the novice reviewer undertaking a review can be a daunting and complex process; by following the stages outlined and being systematic a robust review is achievable. The importance of literature reviews should not be underestimated—they help summarise and make sense of an increasingly vast body of research promoting best evidence-based practice.

What is a literature review?

Choosing a topic, developing your search strategy, carrying out your search, saving and documenting your search, formulating a research question, critical appraisal tools.

• Go to LibrarySearch This link opens in a new window

So you have been asked to complete a literature review, but what is a literature review?

A literature review is a piece of research which aims to address a specific research question. It is a comprehensive summary and analysis of existing literature. The literature itself should be the main topic of discussion in your review. You want the results and themes to speak for themselves to avoid any bias.

The first step is to decide on a topic. Here are some elements to consider when deciding upon a topic:

• Choose a topic which you are interested in, you will be looking at a lot of research surrounding that area so you want to ensure it is something that interests you. 
• Draw on your own experiences, think about your placement or your workplace.
• Think about why the topic is worth investigating.  

Once you have decided on a topic, it is a good practice to carry out an initial scoping search.

This requires you to do a quick search using  LibrarySearch  or  Google Scholar  to ensure that there is research on your topic. This is a preliminary step to your search to check what literature is available before deciding on your question. 

The research question framework elements can also be used as keywords.

• Think about who the population/ sample group. Are you looking for a particular age group, ethnicity, cultural background, gender, health issue etc.
• What is the intervention/issue you want to know more about? This could be a particular type of medication, education, therapeutic technique etc. 
• Do you have a particular context in mind? This could relate to a community setting, hospital, ward etc. 

It is important to remember that databases will only ever search for the exact term you put in, so don't panic if you are not getting the results you hoped for. Think about alternative words that could be used for each keyword to build upon your search. 

Build your search by thinking about about synonyms, specialist language, spellings, acronyms, abbreviations for each keyword that you have.

Inclusion & Exclusion Criteria

Your inclusion and exclusion criteria is also an important step in the literature review process. It allows you to be transparent in how you have  ended up with your final articles. 

Your inclusion/exclusion criteria is completely dependent on your chosen topic. Use your inclusion and exclusion criteria to select your articles, it is important not to cherry pick but to have a reason as to why you have selected that particular article. 

• Search Planning Template Use this template to plan your search strategy.

Once you have thought about your keywords and alternative keywords, it is time to think about how to combine them to form your search strategy. Boolean operators instruct the database how your terms should interact with one another. 

Boolean Operators

• OR can be used to combine your keywords and alternative terms. For example "Social Media OR Twitter". When using OR we are informing the database to bring articles continuing either of those terms as they are both relevant so we don't mind which appears in our article. 
• AND can be used to combine two or more concepts. For example "Social Media AND Anxiety". When using AND we are informing the database that we need both of the terms in our article in order for it to be relevant.
• Truncation can be used when there are multiple possible word endings. For example Nurs* will find Nurse, Nurses and Nursing. 
• Double quotation marks can be used to allow for phrase searching. This means that if you have two or more words that belong together as a phrase the database will search for that exact phrase rather than words separately.  For example "Social Media"

Don't forget the more ORs you use the broader your search becomes, the more ANDs you use the narrower your search becomes. 

One of the databases you will be using is EBSCOHost Research Databases. This is a platform which searches through multiple databases so allows for a comprehensive search. The short video below covers how to access and use EBSCO. 

A reference management software will save you a lot of time especially when you are looking at lots of different articles. 

We provide support for EndNote and Mendeley. The video below covers how to install and use Mendeley. 

Consider using a research question framework. A framework will ensure that your question is specific and answerable.

There are different frameworks available depending on what type of research you are interested in.

Population - Who is the question focussed on? This could relate to staff, patients, an age group, an ethnicity etc.

Intervention - What is the question focussed on? This could be a certain type of medication, therapeutic technique etc. 

Comparison/Context - This may be with our without the intervention or it may be concerned with the context for example where is the setting of your question? The hospital, ward, community etc?

Outcome - What do you hope to accomplish or improve etc.

Sample - as this is qualitative research sample is preferred over patient so that it is not generalised. 

Phenomenon of Interest - reasons for behaviour, attitudes, beliefs and decisions.

Design - the form of research used. 

Evaluation - the outcomes.

Research type -qualitative, quantitative or mixed methods.  

All frameworks help you to be specific, but don't worry if your question doesn't fit exactly into a framework. 

There are many critical appraisal tools or books you can use to assess the credibility of a research paper but these are a few we would recommend in the library. Your tutor may be able to advise you of others or some that are more suitable for your topic.

Critical Appraisal Skills Programme (CASP)

CASP is a well-known critical appraisal website that has checklists for a wide variety of study types. You will see it frequently used by practitioners.

Researchers, academics and librarians all use various terms to describe different types of literature reviews. Indeed there is often inconsistency between the ways the types are discussed. Here are a couple of simple explanations.

The image below describes common review types in terms of speed, detail, risk of bias and comprehensiveness:

"Schematic of the main differences between the types of literature review" by Brennan, M. L., Arlt, S. P., Belshaw, Z., Buckley, L., Corah, L., Doit, H., Fajt, V. R., Grindlay, D., Moberly, H. K., Morrow, L. D., Stavisky, J., & White, C. (2020). Critically Appraised Topics (CATs) in veterinary medicine: Applying evidence in clinical practice. Frontiers in Veterinary Science, 7 , 314. https://doi.org/10.3389/fvets.2020.00314 is licensed under CC BY 3.0

How to Write a Literature Review for a Dissertation

Last Updated: August 4, 2021

This article was co-authored by Christopher Taylor, PhD . Christopher Taylor is an Adjunct Assistant Professor of English at Austin Community College in Texas. He received his PhD in English Literature and Medieval Studies from the University of Texas at Austin in 2014. This article has been viewed 22,403 times.

If you're writing a doctoral-level dissertation in the sciences or humanities, you'll most likely be required to include a literature review. A well-written review brings together the previous work done in your field and places an emphasis upon established points relevant to your topic. This shows your dissertation committee that you're well-read in your specialty area and can contextualize your work within larger conversations in your field. Within the review itself, you’ll need to analyze other scholars’ works, assess their strengths and weaknesses, and synthesize their perspectives with your own work.

Reviewing the Literature

• If you're not sure which formatting guidelines you should be following, ask your committee chair or major professor.

• The number of sources you'll need will vary depending on your field and major professor. While not all fields will require 50 sources (and some may require more), it's a good ballpark figure to start with.
• Make sure that you identify the major and minor fields that your dissertation fits into. Discuss this with your committee and make a list of key terms and concepts to help you as you start collecting sources.

• What research methods do the scholars whose work you're reading use?
• What conflicts have cropped up between different schools of thought?
• How have theories in the field changed over time?
• What names and ideas come up most frequently?
• Write your citations 1 at a time as you read through your sources. Do not try to write several annotations at once.

Structuring the Body of Your Lit Review

• For example, say you’re writing about teaching trends in higher education. You could have 1 subheading about online-based teaching, another about uses of technology in the classroom, and another about experience-based teaching.

• Organizing sources will allow you to enumerate the ways in which other sources agree with, disagree with, or otherwise modify the sources of highest importance.

• For example, you’d summarize a source about technology in the classroom written in 1967 before one written in 1976.

Writing the Lit Review

• For example, maybe the work you’re doing in your dissertation expands on what’s been done in one subsection of the works you’re reviewing.

• For example, if a frequently-cited article within the literature relies on faulty research or poor research, point this out when addressing the article.

• Synthesizing sources by method by comparing different academic works that follow a similar operating method (this is especially prevalent in the hard sciences)
• Synthesizing sources by topic, since your lit review should be broad enough to cover at least 4–5 different subfields within your area of study

• So, don’t switch between imitating the sentence structures and vocabularies of each of the sources you’re summarizing.

• A thoroughly checked review has a better chance of being accepted by your dissertation committee.

Expert Q&A

• Give yourself at least 4-6 months to write the literature review. Although you won’t be coming up with new, original ideas for the lit review, it still takes a substantial chunk of time to write. Thanks Helpful 0 Not Helpful 0

About this article

To write a literature review for a dissertation, start with an introduction that gives an overview of the topic. In this overview, emphasize the topic's importance, identify recent research, and clarify how that research applies to the body of your dissertation. For example, the work in your dissertation might expand on what’s been done in one subsection of the works you’re reviewing. In your review, summarize 40 to 50 different sources in a way that provides an analysis of their strengths. It’s not realistic to write an entire paragraph for each source, so look for ways to group sources together and show your committee that you’re able to make high-level connections between them. As you write, be sure to maintain your own writing voice by trying to think of it as a conversation between yourself and the sources.

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.

A practical approach to the process of writing a dissertation

09 October, 2017

Writing a dissertation does not have to be stressful and should be a vehicle for learning, not a chore. This article offers practical advice for student nurses embarking on the task

While many student nurses find the task daunting, writing a dissertation is essentially a powerful vehicle for learning; it is an opportunity to work on methodology and organisational skills, develop an appreciation of research, and demonstrate critical thinking. With the help of a good supervisor, a carefully planned dissertation will develop almost naturally, as long as students follow a few basic rules. This article considers the essentials of writing a dissertation and offers practical guidance to students.

Introduction

Many student nurses feel overwhelmed by the task of writing a dissertation, uncertain how to approach it and doubtful about their chances of success. Few are fully confident that they know how to go about writing the dissertation, manage the supervisory relationship and highlight the essentials of the topic they wish to examine. However, writing a dissertation is a learning process, and need not be such an onerous task if it is carefully planned.

A dissertation can be defined as the report of a process; it may also be seen as a long essay (Biggam, 2015). By comparison, a thesis is more sophisticated and adds to the knowledge in a field, or challenges accepted norms to bring about changes in established understanding. Undergradu-ates and taught master’s degree students are more likely to produce a dissertation, as do many master’s students, whereas students at doctoral level are more likely to write a thesis.

Writing a dissertation equates to developing an understanding of research or systematic enquiry rather than generating new evidence; that is the purpose of a doctoral thesis. While there are various methods according to the nature of the project, the main purpose of a dissertation is to enable students to demonstrate organisational skills, beginning insights into research, and deeper, more critical understanding of their chosen focal topic. However, there are commonalities be-tween a dissertation and thesis, especially around the importance of good supervisory relationships. This article focuses on dissertations, offering a framework for students embarking on – or stuck in the middle of – the process of writing one.

Purpose of a dissertation

Students are asked to write a dissertation to demonstrate their ability to focus on a subject, examine it in detail through systematic enquiry and identify relevant theories. They need to show they are capable of presenting work in an orderly, academic form, clearly demonstrating a working knowledge of their chosen subject. Equally important is the development of various levels of critical insight, depending on the level of degree for which the dissertation is to be submitted – undergraduate or master’s. Box 1 summarises what is expected from you in a dissertation.

Box 1. What your dissertation must demonstrate

• Ability to delve into a subject through systematic enquiry
• Capacity to present written work in an orderly, academic form
• Working knowledge of a subject
• Clarity of purpose, clarity of thought and sophistication of argument
• Ability to focus, plan, organise and work methodically
• Ability to think critically

Getting started

Acording to Wisker (2013) a dissertation is a large piece of work requiring careful planning, good time management, critical thinking, conceptual understanding and adherence to practices for completion. The time taken initially to decide on the topic, approaches and resources will be time well spent.

Many students consider identifying and refining the topic of their dissertation to be one of the most difficult elements in the process. It is fair to say that once the topic has been defined, the rest unrolls like a carpet – as long as you follow a few basic rules (Box 2).

Box 2. Basic rules for writing a dissertation

• Refine the topic, spending time with your supervisor at this stage
• Choose question(s), where relevant, that will likely produce interesting answers
• Consider resources
• Do not hesitate to write in the first person if appropriate
• Put effort and care into every stage of the process
• Justify your choices rather than simply stating them
• Produce a lively and informed discussion
• Follow the format requirements of your institution/supervisor

It is important to avoid chaos and to put effort and care into every stage of the process; the SCARY checklist contains useful advice on what a dissertation should and should not be (Box 3).

Box 3. The SCARY checklist

Your dissertation should be SCARY , in other words:

S traightforward: avoid waffling or overcomplicating ideas; you should, however, demonstrate complexity when discussing findings and literature

C lear and unambiguous: whatever you set out to do must be easily defined and may be trailed for audit

A chievable: within the time frame, limits of the remit, available resources and size limitations

R ecency, ensure that the material you are using to inform the work is current; it might be wise to ensure that all literature dates from the last 10 years or so, depending on the subject matter. Unless older work is seminal, avoid citing it and seek newer material; never use literature just because it is convenient or to hand

Y ours: do not be tempted to claim anyone else’s work as your own

One key piece of advice is that it must be the student’s own work, which means plagiarism must be avoided (Box 4).

Box 4. Plagiarism: do not go there

As Singh and Remenyi (2016) explain, plagiarism is using, in an essay or dissertation, ideas that have been sourced from work published by other authors without acknowledging them. It is academic misconduct to fail to acknowledge the original source, a point echoed by Biggam (2015). In the worst case scenario, plagiarism can lead to the candidate’s work being disallowed.

If you are tempted to use the work of others and claim it for yourself, the advice is simple: do not go there.

The qualities that distinguish an outstanding dissertation from an average one include clarity of purpose, clarity of thought and sophistication of the argument. A first-class submission will be highly organised and focused, clearly demonstrating critical insight, as opposed to a simple, unquestioned description.

Refining the topic

A topic that may seem obvious at the outset can prove to be too vague or too complex. It can be helpful to distil your ideas using a framework such as Lowry’s reflective triangle (Lowry, 2016). Start by making notes on what interests you and why (the ‘case’), then put these into the ‘context’ and consider all the ‘variables’ (Fig 1). For example, you might have an interest in educating patients and want to explore this case in more depth. The context might be your recent experience of a patient being unclear about information on treatment options. Given the importance of patients understanding treatment options so they can make informed decisions, the scenario might appear more complex than it first seemed. You might want to consider the impact on you as a practitioner, who else was involved, what was particularly important and why (the variables). Your reflections will eventually crystallise into a clearer topic and will help you justify your choice.

This part of a dissertation is often seen as the most challenging. Without a clear focus, the rest of the process is likely to stall, so spending time with your supervisor at this stage is invaluable. Go it alone if you will, but it is far better to nurture the supervisory relationship (Kimani, 2014).

Determining the research question

Not all dissertations need a question or questions; some can be purely observational – for example if they use grounded theory. When questions are involved, however, these must be relevant and have a reasonable chance of producing answers.

Unless the subject matter makes it impossible, you should never use a closed question (questions starting with “is”, “are”, “does” or “can”), as the answer will inevitably be yes or no. For example, the answer to the question “Is the process of completing a dissertation arduous?” is almost certainly yes, to an extent, so the question has no real value. A more interesting alternative would be to ask “To what extent is completing a dissertation arduous?”. This offers something to explore and play with to produce a discussion. If you study human society in any shape or form, you will quickly discover that it is seldom binary and rarely fits an ‘either/or’ format.

Considering resources

While refining your topic and research question, you also need to identify and justify the resources you may need, such as help from a statistician, support with transcribing data or advice from experts. Consider whether these resources will be available within the time frame and budget. It would be unwise to seek answers to questions that require disproportionate resources.

Using discursive writing

Students tend to avoid discursive writing, preferring to report rather than to argue, but Kamler and Thomson (2006) emphasise the importance of producing lively and informed discussions. There are opportunities for discussion in various sections of a dissertation, including in the literature review, and it can be used throughout your work, starting with the justification of your choice of topic and methods.

Choosing the right pronoun

It has long been debated whether to use the personal pronoun in academic work; the upshot is that, where justified, there is no reason to avoid writing in the first person. As Kamler and Thomson (2006) put it, “‘I’ is not just a matter of personal choice. There are epistemological/methodological and rhetorical reasons for choosing to use the first person pronoun”. Conversely, trying to shoehorn the personal pronoun (or third person) into your writing when it is unnecessary detracts from the intrinsic quality of the dissertation.

Discuss your preference with your supervisor and be ready to argue your case; the reason for your choice must be clear from the outset. Whatever choice you make – first or third person – must be adhered to throughout, so never alternate between pronouns.

Format and elements of a dissertation

Once you have a general feel for what your dissertation is going to look like, you can get started. The requirements for format and what elements the dissertation should include vary according to institutions and supervisors, so be guided by them. More information on the practicalities of pre-paring a research-based dissertation can be found in Bowen (2005). Generally, all the elements described below are needed in one form or another. At each step, remember to justify your choices as opposed to alternatives, rather than simply stating them and moving on. In terms of style, avoid colloquialisms and discipline your thinking to search for relevant illustrative expressions.

Although the introduction to the dissertation comes first it should be written last, after everything else is complete. Only then will you know exactly what is in your dissertation and how to introduce it.

The background section tells the story of what led you to undertake this work – for example, a recent placement, clinical experience or a presentation in an academic forum. It brings the reader to the table, so to speak.

Aims and objectives

Aims and objectives must be determined at the outset. Have at least one (main) aim and four (contributory) objectives: fewer than four objectives might appear superficial, especially considering that the aim has been deemed interesting enough to merit a study. Objectives must be relevant to the aim(s), and aims and objectives must be clearly stated and explained.

The aim is the overall destination and the objectives are what you need to do to get there; for example, if your aim was to help women to decide what method of contraception to choose, your objectives would include establishing what methods are available, examining the risks and benefits of each, and evaluating different forms of patient information.

Literature review

The literature review – sometimes called literature search or literature enquiry – is crucial. What you have read must be current and relevant, and you need to show that you have examined it critically. If one author’s assertion is contradicted by another, your role is to unravel the arguments and extract meaning from them. The fact that authors have had their work published does not mean they are necessarily right.

Synthesise what you have read, bring the information together and demonstrate how it has contributed to your thinking. From your reading you will develop ideas on how to investigate your topic – including what design best fits your purpose.

Journal articles are generally more focused and detailed than books. Ensure the journals you cite are peer-reviewed: this means its articles have been scrutinised by people with the relevant spe-cialist expertise before being accepted for publication. How many articles or books you include depends on the nature of your work. You are likely to need at least 20 current articles or books to make sense of your topic. Fewer sources may betray an unwillingness to delve into the subject, whereas featuring a huge amount of literature may indicate you have skimmed through it. Be selective and be prepared to justify your choice of included work.

The design – also referred to as approach or method – is the way in which you explore your topic. This section can adopt various presentations but should be clear and succinct, and you should avoid becoming mired in uncertainties. It may feature:

• The epistemological approach – for example qualitative or quantitative, or perhaps eclectic – and why you made that choice;
• The method – for example, if you have chosen a quantitative approach your method could be a survey, while a qualitative approach could be the observation of informants and interpretation of their behaviour with the help of follow-up interviews. These methods are by no means exhaustive and relevant texts on research principles, such as Parahoo (2014); Moule and Aveyard (2016); Ellis (2016) will help you select your method.
• Resources needed for your project;
• Any perceived limitations, such as availability of informants, response rates or equipment, and how these were dealt with.

Ethical approval

Research is awash with ethical challenges; you need to identify them early and show what steps you have taken to address them. Do refer to the theories on ethics that you have used to guide your thinking. As a general rule, undergraduates should not be encouraged to involve patients in their research projects, but they will still need to secure ethical approval if they intend to involve peers, staff or any other informants who could potentially be harmed. Obtaining ethical approval is a long and sometimes complex process that should not be taken lightly.

This section states what sources you derive information from; for example, this could be literature only, different types of literature, individual informants or observations.

Describe what you have done, what worked and what did not. Do not avoid exploring errors in your work, but when doing so, demonstrate how they have contributed to your understanding.

This is the section where you describe what has emerged from your study and what you think needs to be examined further (and why). Do not merely end with a series of superficial comments about what else could be done, but explain what brought you to these views.

The discussion is your chance to shine. It is likely to be longer than most other sections – if not there may be a problem. Start by stating what resulted from your enquiry, and every time you make a statement, ask yourself: so what? It may seem odd, but this self-enquiry will result in deeper insights, which will impress examiners.

If you want to excel, incorporate the findings from the literature review into your discussion and explore whether the findings from your work concur with or differ from the literature. You can further enhance the discussion by integrating fieldwork, findings and ethical challenges. The more fully you engage with the dissertation at this stage, the more sophisticated the end product will be.

Conclusions

The conclusions (or recommendations) need to be brief, draw everything together and suggest what needs to happen next and why.

Your work must include a carefully compiled list of literature cited in your dissertation. Bear in mind that examiners do check references – especially if they are themselves among the authors cited. They may find incomplete reference lists – or, even worse, their published work misquoted or wrongly interpreted – extremely irritating. Refer to your institution’s guidelines for reference protocols.

A dissertation is a means for students to demonstrate they can work methodically and think critically. It is also a powerful vehicle for learning, and one that may well stimulate students to become further involved with systematic enquiry. At the very least, it will engender an appreciation of the process of research.

• Many students feel overwhelmed by the task of writing a dissertation
• A dissertation that has been carefully thought through should develop naturally
• Time taken initially to decide on the topic, questions and methods will be time well spent
• Dissertations must be clear, organised and focused, and demonstrate critical insight
• Plagiarism is academic misconduct and must be avoided

I am a 3rd year student nurse embarking on my dissertation so found this article interesting. It is true, most students do feel nervous and overwhelmed at the thought of writing a dissertation especially on top of other assignments and being in practice.

How to undertake a literature search

Introduction.

Undertaking a literature search can be a daunting prospect. By breaking the exercise down into smaller steps, you can make the process more manageable. The following ten steps will help you complete the task from identifying key concepts to choosing databases for your search and saving your results and search strategy. It discusses each of the steps in a little more detail with examples and suggestions of where to get help.

There are ten steps to undertaking a literature search which we'll take you through below:

🎬 - Indicates a video is available with more information.

Please click on the boxes below to get a bit more detail on each step.

First, write out your title and check that you understand all the terms. Look up the meaning of any you don’t understand. An online dictionary or medical encyclopaedia may help with this.

If your search is for a dissertation, you may need to choose your own research question. In this case, you will need to consider whether there is likely to be enough research on your topic. Alternatively, if your topic is too broad, you could be overwhelmed by the number of references.

One way of checking how much is written on your topic is to use Library Search. Most libraries offer a Library Search or discovery tool. It provides a quick search across all the library’s holdings. You can also limit your search by date or type of document. If you just need a few references to help you write an essay, Library Search may be helpful. It also gives quick access to full text items.

Next, you need to identify your key concepts. One way to do this is to look at your title and identify the most important words. Ignore words that tell you what to do with the information you find eg evaluate, assess, compare, as these are not generally used as search terms. In the example below, key concepts have been highlighted:

Evaluate the effectiveness of a mindfulness intervention on the health-related quality of life of rheumatoid arthritis patients

Another way to do this is to break down your title using the PEO framework:

P = Population    E = Exposure    O = Outcome 

This works well where there is no comparison between two types of treatment or intervention.

In our example:

P = rheumatoid arthritis patients

E = mindfulness

O =  health related quality of life

Other question formats are available such as PICO or SPIDER

Tip: Not all search topics will include every element of PICO – some include fewer items.

Once you have identified the key concepts, it’s important to think of any other terms or phrases that might have a very similar meaning. Including such synonyms will make your search as thorough as possible. For example, if your topic is looking for articles on Staff attitudes , you might also use the terms:

• Staff perceptions 
• Staff opinions
• Stereotyping
• Labelling 

If the database you are using has a list of subject heading s , this may help you to find the most appropriate term for your subject. Some databases provide definitions for terms used in the database and may suggest related terms.

A comprehensive search will usually include both subject headings from databases and terms that you have thought of yourself.

Tip: Often your search term will be a phrase instead of a single word. To carry out phrase searches, use double quotes, for example “problem drinking”.

Once you have chosen your search terms, you need to think about the best databases for your topic. The databases you choose will depend on the search question and the libraries you have access to.

Tip: It’s well worth taking a few minutes to get to know the databases available on the Library webpages and what they cover.

The next step is to combine your search terms in such a way that you only retrieve the more relevant references for your search question. In order to do this you need to build a search strategy . This involves using Boolean operators such as AND , OR and NOT .

AND narrows the results of the search by ensuring that all the search terms are present in the results. 

OR broadens the results of the search by ensuring that any of the search terms are present in the results.

NOT limits the results by rejecting a particular search term. Be careful with NOT because it will exclude any results containing that search term regardless of whether other parts of the article might have been of interest.

OR will broaden your number of results while AND will produce fewer results.

Try using this  Search-plan-worksheet   to break your topic down into concepts. These can then be linked together when you run the search. You can also add synonyms within each concept box. The yellow limits box is a prompt to think about any limits you want to apply when searching. This leads us to Step 6.

Tip: Most databases will allow you to use a truncation sign (*) or wildcard (?) to pick up various different endings to words or alternative spellings.

For example:  alcohol* would pick up alcohol, alcoholic, alcoholism, etc

Sm?th would find Smith and Smyth

The next step is to think about any other restrictions you want to make to your results.

Common limiters found on databases include:

• Peer reviewed articles
• Research articles
• Age group (adult, child, older person)
• Document type

Not all databases allow all of the limiters above.

When writing a dissertation, primary research articles are normally required. Where the database allows you, try limiting to research articles only.

Non-research materials can also be useful as an overview of your topic; for example a literature review can give an analysis of what has already been written on a topic.

The video below includes a demonstration of how limits can be applied using the CINAHL database as an example:

CINAHL - advanced

Once you have identified all your search terms and any limits you want to apply, you are ready to run your search on the databases you have chosen. 

Once you have some search results, you can look through them and start to select those that look relevant to your literature search. It is likely you will reject some because they are not quite what you wanted but there will be others that can be marked for further attention.

The title of an article on its own may not tell you very much; read the abstract quite carefully to see if the article is relevant or not.

Tip: You can show more details for each record by clicking on the article title. On some databases, there may be an abstract for the article which you can open. 

If you find you are either generating more results than you can possibly look at or too few results to write about, be prepared to adjust your search terms and the way they are combined.

If you get too many results you could try: •limiting to just the most recent material •adding another term or concept and linking it using “AND” •limiting to a particular country or geographical area such as UK

If you get too few results, you might try: •expanding your date range •removing any geographical limits you have applied  •removing the least important term or concept

Tip: Be prepared to try other databases and keep searching until you feel confident you have found enough relevant material.

Once you have selected some articles that look relevant for your piece of work, you will need to save them so that your hard work is not wasted.

At the same time, you will want to save your search strategy . This is a record of the terms you searched, how you combined them, any limits you applied and how many results you found.

You will also need to choose a way to save your results. One way is to email the results to yourself and this can be done from all the databases .

Another way is to export your results to reference management software such as Zotero, RefWorks, EndNote or Mendeley. This software allows you to collect, organise and cite research. It is suitable for managing references over a long period of time. 

The RCN Library and Museum provides help with using Zotero . 

Tip: Keep a record of all the databases you use as you carry out your search. It is also a good idea to note where you found any references you subsequently use for your dissertation.

The final step is to obtain the full text of the articles identified in your search which you believe may be useful for your assignment. If you are lucky, many of these will be available electronically and you may just be able to follow a link to the full text.

Alternatively you can copy and paste your article title into the Library search box  and if it is available as full text, a hyperlink will be shown which will link you to the document.

If you are studying elsewhere and have access to a university or hospital library, they may subscribe to different journals to the RCN Library so it is worth exploring what they can offer. If your library does not have either an electronic copy or a physical copy, you may need to request the article by interlibrary loan .

Tip: It is also worth using Google or other browsers to check for the article title you require. Sometimes the article has been made freely available on the internet by the authors.

Boolean operators – words (AND, OR and NOT) which can be used to combine search terms in order to widen or limit the search results.

Database – this is an online collection of citations to journal articles which have been indexed to make retrieval easier. Some databases which also provide full text access to the articles.

Limits – these are options within a database which allow search results to be broken down further. Common limits are year(s) of publication, document type and language. MEDLINE and CINAHL allow age limits too.

Search Strategy – the list of search terms and limits used to retrieve relevant articles from a database in order to answer a search question.

Subject headings – terms that have been assigned to describe a concept that may have many alternative keywords. All these alternative keywords or terms are brought together under the umbrella of this single term. Most health-related databases use subject headings.

Additional information

If after following these steps, you still can’t find what you are looking for, remember that there is always help available at your library. The RCN Library and Museum offers a range of help materials via our Literature searching and training pages . These include: • Databases guides in electronic and printed formats • Video tutorials on how to search the databases • 1-1 training sessions pre-bookable via the RCN website face to face or via zoom
