Evaluate the current "state of the art" for the body of knowledge reviewed, pointing out major methodological flaws or gaps in research, inconsistencies in theory and findings, and areas or issues pertinent to future study.3.
Conclude by providing some insight into the relationship between the central topic of the literature review and a larger area of study such as a discipline, a scientific endeavor, or a profession. Open web sources (somebody's home page, as opposed to peer-reviewed online journals or licensed database sites that provide access to scholarly works) are not usually considered reliable sources for academic research and should be used sparingly, if at all, and only after careful research into the sponsors of a site.
Describe the relationship of each work to the others under consideration4.
Identify new ways to interpret, and shed light on, any gaps in previous research5.
Point out overall trends in what has been published about the topic; or conflicts in theory, methodology, evidence, and conclusions; or gaps in research and scholarship; or a single problem or new perspective of immediate interest.3.
Establish the writer's reason (point of view) for reviewing the literature; explain the criteria to be used in analyzing and comparing literature and the organization of the review (sequence); and, when necessary, state why certain literature is or is not included (scope). Group research studies and other types of literature (reviews, theoretical articles, case studies, etc.) according to common denominators such as qualitative versus quantitative approaches, conclusions of authors, specific purpose or objective, chronology, etc.2.
In other words, don't use generally available internet search engines for your literature review.2.
Place each work in the context of its contribution to the understanding of the subject under review3.
A literature review is a specific type of research paper that focuses on published literature on a given topic.
It is often the first step in doing original research, either scientific or otherwise.
