What is a Literature Review?

A literature review is an overview or discussion of existing literature on a particular topic.  The literature may come from books, articles, reports, or other formats. 

It's a review because it usually contains a summary, synthesis, or analysis of the central arguments in the existing literature.  A literature review does not present an original argument, but instead presents the arguments of others in a different context.

In research articles with a narrow focus, the literature review may form a brief introductory section.  In theses, dissertations, or articles with a broad focus, the literature review may be a lengthy discussion of all relevant research.



A literature review can serve any of several purposes.  It can ...

  • summarize the existing research on a particular topic
  • introduce the important research on a topic
  • point out contradictory or controversial studies or methodologies
  • raise a question or highlight an issue for further study
  • help to contextualize the current research
