What is a literature review?
A literature review is a discussion of previously published information on a particular topic, providing summary and connections to help readers understand the research that has been completed on a subject and why it is important. Unlike a research paper, a literature review does not develop a new argument, instead focusing on what has been argued or proven in past papers. However, a literature review should not just be an annotated bibliography that lists the sources found; the literature review should be organized thematically as a cohesive paper.
Why write a literature review?
Literature reviews provide you with a handy guide to a particular topic. If you have limited time to conduct research, literature reviews can give you an overview or act as a stepping stone. For professionals, they are useful reports that keep them up to date with what is current in the field. For scholars, the depth and breadth of the literature review emphasizes the credibility of the writer in his or her field. Literature reviews also provide a solid background for a research paper’s investigation. Comprehensive knowledge of the literature of the field is essential to most research papers.
Who writes literature reviews?
Literature reviews are sometimes written in the humanities, but more often in the sciences and social sciences. In scientific reports and longer papers, they constitute one section of the work. Literature reviews can also be written as stand-alone papers.
