Some questions to help evaluate research, from the Boston College Libraries: http://libguides.bc.edu/litreview/phase4
For some classes, you will be asked to focus your research on scholarly articles. Scholarly articles (also known as peer-reviewed, refereed, or academic articles) are distinguished by going through the peer review process, in which they are evaluated and given feedback by experts in a field.
How can you tell whether an article is peer-reviewed? See "verifying peer-review" for more information.
