Development of the Literature Review



Four Stages of Literature Review

  1. Problem formulation — which topic or field is being examined and what are its component issues?
  2. Literature search — finding materials relevant to the subject being explored.
  3. Data evaluation — determining which literature makes a significant contribution to the understanding of the topic.
  4. Analysis and interpretation — discussing the findings and conclusions of pertinent literature.


Consider the following issues before writing the literature review:


If your assignment is not very specific about what form your literature review should take, seek clarification from your professor by asking these questions:

  1. Roughly how many sources should I include?
  2. What types of sources should I review (books, journal articles, websites; scholarly versus popular sources)?
  3. Should I summarize, synthesize, or critique sources by discussing a common theme or issue?
  4. Should I evaluate the sources?
  5. Should I provide subheadings and other background information, such as definitions and/or a history?


Find Models

Use the exercise of reviewing the literature to examine how authors in your discipline or area of interest have composed their literature review sections. Read them to get a sense of the types of themes you might want to look for in your own research or to identify ways to organize your final review. The bibliography or reference section of sources you’ve already read are also excellent entry points into your own research.


Narrow the Topic

The narrower your topic, the easier it will be to limit the number of sources you need to read in order to obtain a good survey of relevant resources. Your professor will probably not expect you to read everything that’s available about the topic, but you’ll make your job easier if you first limit scope of the research problem. A good strategy is to begin by searching the HOMER catalog for books about the topic and review the table of contents for chapters that focuses on specific issues. You can also review the indexes of books to find references to specific issues that can serve as the focus of your research. For example, a book surveying the history of the Israeli-Palestinian conflict may include a chapter on the role Egypt has played in mediating the conflict, or look in the index for the pages where Egypt is mentioned in the text.


Consider Whether Your Sources are Current

Some disciplines require that you use information that is as current as possible. This is particularly true in disciplines in medicine and the sciences where research conducted becomes obsolete very quickly as new discoveries are made. However, when writing a review in the social sciences, a survey of the history of the literature may be required. In other words, a complete understanding the research problem requires you to deliberately examine how knowledge and perspectives have changed over time. Sort through other current bibliographies or literature reviews in the field to get a sense of what your discipline expects. You can also use this method to explore what is considered by scholars to be a “hot topic” and what is not.
