What is the Purpose of a Literature Review?
A literature review is a synthesized account that evaluates the publications in a subject area, which are written by scholars or researchers. Literature reviews are used in a variety of contexts:
- standalone article
- introduction to a research paper
- introduction to a research prospectus
- an early chapter in a master's thesis or doctoral dissertation
Note that a literature review evaluates the literature; it does not simply summarize it.
What a Literature Review is Not?
A literature review is NOT:
- an annotative bibliography
- descriptive list
- summary of your readings
You need to be evaluating the literature and explaining how it leads to your research question or supports your thesis statement.
