Writing an Effective Literature Review

Abstract

A literature review can be an informative, critical, and useful synthesis of a particular topic. It can identify what is known (and unknown) in the subject area, identify areas of controversy or debate, and help formulate questions that need further research. There are several commonly used formats for literature reviews, including systematic reviews conducted as primary research projects; reviews written as an introduction and foundation for a research study, such as a thesis or dissertation; and reviews as secondary data analysis research projects. Regardless of the type, a good review is characterized by the author's efforts to evaluate and critically analyze the relevant work in the field. Published reviews can be invaluable, because they collect and disseminate evidence from diverse sources and disciplines to inform professional practice on a particular topic. This directed reading will introduce the learner to the process of conducting and writing their own literature review.
