According the the APA Publication Manual, a literature review is a "critical evaluation of material that has already been published" about your topic. The links below will help you understand how and why to research and write a literature review.
Finding Scholarly Articles
Databases for Business Research
Completing a literature review requires you to examine the body of literature relevant to your research question. Use these databases to find scholarly articles on business topics.
Researching Non-Business Topics
Some students choose to research a discipline other than business, such as health care, engineering or sports. These topics are not widely covered in the Walsh databases. You may want to use another college or university library for your research. Talk to a librarian for information on access to other academic libraries.
