      A literature review discusses published information in a particular subject area within a certain time period. It can be just a simple summary of the sources but it usually has an organizational pattern and combines both summary and synthesis.
      Literature reviews also provide a solid background for a research paper's investigation.
      Generally, the purpose of a review is to analyze critically a segment of a published body of knowledge through summary, classification, and comparison of prior research studies, reviews of literature and theoretical articles.

      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.
