The focus of a literature review is to provide an overview of sources explored while researching a particular topic. This is distinct from a standard research paper, whose purpose is to develop a new argument. The literature review may be incorporated into a larger research project, or it could be developed as a separate document.
Steps to Writing a Literature Review
See the Video Tutorials (in the next tab over) for a breakdown of the steps and process.
The following summary of steps is adapted from the OWL Social Work Literature Review Guidelines.
Cast a wide net to find a variety of articles loosely related to your subject.
Narrow your articles to those that are most relevant to your subject and purpose.
Critically evaluate the articles, looking at methodology, statistics, results, theoretical framework, author's purpose, etc.
Look for themes in the literature to organize the articles in a meaningful fashion. For example, group case studies together.
Offer a critical assessment of the literature that goes beyond a simple summary.
Suggest further areas for research that go beyond what you have reviewed. What new questions need to be explored?
Primary sources are original works in a given field. In social and behavioral sciences, these are generally articles written with new data and findings. Literature reviews should focus heavily, if not exclusively, on primary sources.
Secondary sources analyze primary sources. These are not sources of original research, but they will discuss original research that is presented elsewhere.
Tertiary sources are consolidated discussions of primary and secondary sources. While secondary sources directly discuss primary sources, tertiary sources summarize a wide variety of sources. The most common types of tertiary sources are encyclopedias and dictionaries.
