A literature review is an account of what has been published on a topic by accredited scholars and researchers. [...] In writing the literature review, your purpose is to convey to your reader what knowledge and ideas have been established on a topic, and what their strengths and weaknesses are. As a piece of writing, 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). It is not just a descriptive list of the material available, or a set of summaries.
Your professor will establish guidelines for writing a literature review. The following video, Literature Review: An Overview for Graduate Students, by North Caroline State University Libraries is an excellent starting point.
