Articles in a peer-reviewed or "refereed" journal are reviewed by experts (usually faculty members) with credentials in the article's field of study prior to publication. Many Harvard article databases allow you to limit your search results to only include peer-reviewed journals.

Other material like white papers and policy briefs that are not peer-reviewed can still be valuable for your literature review. Relevant preprints that will eventually be peer-reviewed or gray literature unlikely to be published in a journal should be included as long as they pass the C.R.A.P. test, evaluating Currency, Relevancy, Authority, and Purpose.
