What is a Literature Review?
A literature review is both a summary and an explanation of the complete and current state of knowledge on a narrowed topic as found in academic books and journal articles.
What are the Purposes of a Literature Review?
- situate your work in its discipline/area/subfield
- develop an understanding of how knowledge in your discipline/field/area has changed over time
- develop mastery of what's known in your area, and part of the larger discipline that contains it
- compare different conceptual or sub-disciplinary approaches to your topic
- compare and contrast different theoretical schools or leading researchers in your area
- identify methodologies that you might use in your work

Tips for effective searching
If you find one relevant article for your research it can lead to other relevant papers by the following:
- using the databases, including Omni, look to find all papers & books published by the author or co-authors
- explore the bibliography in the paper for sources
- using Web of Science or Scopus, look for articles that cite the article you found. Remember, some databases will also list citing articles but those lists are limited to the current database. The Web of Science and Scopus are more comprehensive, with coverage from multiple databases.
- Remember to see if an citing article has itself been cited.
