Literature Review

What is a Literature Review?

A literature review provides your reader with an account of what has been published on a specific topic or subject by experts, scholars and researchers in the field/discipline. You might be asked to write a literature review as a separate assignment, but in most cases it functions as a part of the introduction to an essay, research report or thesis.

When writing a literature review, your aim is to inform the reader about what knowledge and ideas have been established on a topic or subject and what their strengths and weaknesses are. The literature review must be defined by a guiding concept (e.g., your research objective, the problem or issue you are discussing, or your argumentative thesis).

Remember! It is NOT just a descriptive list of the resources available, or a set of summaries.

What is Synthesis?

What is Synthesis? Synthesis writing is a form of analysis related to comparison and contrast, classification and division. On a basic level, synthesis requires the writer to pull together two or more summaries, looking for themes in each text. In synthesis, you search for the links between various materials in order to make your point. Most advanced academic writing, including literature reviews, relies heavily on synthesis. (Temple University Writing Center)  

How to Synthesize in a Literature Review

Literature reviews synthesize large amounts of information and present it in a coherent, organized fashion. In a literature review you will be combining material from several texts to create a new text – your literature review.

You will use common points among the sources you have gathered to help you synthesize the material. This will help ensure that your literature review is organized by subtopic, not by source. This means various authors' names can appear and reappear throughout the literature review, and each paragraph will mention several different authors. 

When you shift from writing summaries of the content of a source to synthesizing content from sources, there is a number things you must keep in mind: 

  • Look for specific connections and or links between your sources and how those relate to your thesis or question.
  • When writing and organizing your literature review be aware that your readers need to understand how and why the information from the different sources overlap.
  • Organize your literature review by the themes you find within your sources or themes you have identified. 

Consider This

  • What is the specific thesis, problem, or research question that my literature review aims to define?
  • What type of literature review am I conducting? Am I looking at issues of theory, methodology, policy, quantitative research (e.g. interviews, observations), qualitative research (e.g., studies, surveys, statistics)?
  • What is the scope of my literature review? What types of publications am I using (e.g., journals, books, government documents)?
  • What discipline am I working in (e.g. Public Health, Nursing, Kinesiology etc.)?
  • Has my search for sources been wide enough to ensure that I have found all the relevant material?
  • Has it been narrow enough to exclude irrelevant material?
  • Is the number of sources I've used appropriate for the length of my paper (i.e. if your literature review is part of a larger paper or assignment)?
  • Have I critically analyzed the resources I found?
  • How will I avoid just listing and summarizing resources? Do I assess them, discussing strengths and weaknesses?
  • Have I cited and discussed studies contrary to my perspective?
  • Will the reader find my literature review relevant, appropriate, and or useful?

Formatting

FIRST, ASK YOUR INSTRUCTOR!

The format of a literature review may vary from discipline to discipline and from assignment to assignment. However, a literature review must do these things:

  1. Be organized around and related directly to the thesis or research question you are developing
  2. Synthesize results into a summary of what is and is not known
  3. Identify problematic areas or areas of controversy in the literature
  4. Formulate questions or issues that need further research

Remember! A literature review is not a list describing or summarizing one piece of literature after another.

Try and avoid starting every paragraph with the name of a researcher or the title of the work. Rather, try organizing the literature review into sections that present themes or identify trends, including relevant theories. You are not trying to list all the material published on a topic, but to synthesize and evaluate it according to the guiding concept of your thesis or research question.

Consider These for Each Source

  • Has the author formulated a problem/issue?
  • Is the problem/issue clearly defined and is its significance (scope, severity, and relevance) clearly established?
  • Could the problem/issue have been approached more effectively and or from another perspective?
  • What is the author's research orientation (e.g., interpretive, critical science, combination)?
  • What is the author's theoretical framework (e.g., psychological, developmental, feminist)?
  • What is the relationship between #4 and #5?
  • Has the author evaluated the literature relevant to the topic (i.e. does the author include a literature review and or provide sources that take positions she/he does not agree with)?
  • How accurate and valid are the measurements, statistics or data the author has provided?
  • Is the analysis of the measurements, statistics or data accurate and relevant to the research question?
  • Are the conclusions validly based upon the data and analysis?
  • · How does the author structure the argument? Can you retrace the steps he/she takes and analyze the flow of the argument to see if it progresses logically?
  • In what ways does this piece contribute to our understanding of the topic, and in what ways is it useful? What are the strengths and limitations?
  • How does this book or article relate to my thesis or research question?
