The literature review, whether embedded in an introduction or standing as an independent section, is often one of the most difficult sections to compose in academic writing. A literature review requires the writer to perform extensive research on published work in one’s field in order to explain how one’s own work fits into the larger conversation regarding a particular topic. This task requires the writer to spend time reading, managing, and conveying information; the complexity of literature reviews can make this section one of the most challenging parts of writing about one’s research. This handout will provide some strategies for revising literature reviews.
Because literature reviews convey so much information in a condensed space, it is crucial to organize your review in a way that helps readers make sense of the studies you are reporting on. Two common approaches to literature reviews are chronological—ordering studies from oldest to most recent—and topical—grouping studies by subject or theme. Along with deliberately choosing an overarching structure that fits the writer’s topic, the writer should assist readers by using headings, incorporating brief summaries throughout the review, and using language that explicitly names the scope of particular studies within the field of inquiry, the studies under review, and the domain of the writer’s own research. When revising your own literature review, or a peer’s, it may be helpful to ask yourself the some of the following questions:
The primary purpose of the literature review is to demonstrate why the author’s study is necessary. Depending on the writer’s field, it may or may not be clear that research on a particular topic is necessary for advancing knowledge. As the writer composes the literature review, he or she must construct an argument of sorts to establish the necessity of his or her research. Therefore, one of the key tasks for writers is to establish where gaps in current research lie. The writer must show what has been overlooked, understudied, or misjudged by previous studies in order to create space for the new research within an area of academic or scientific inquiry.
