What are "peer reviewed articles"?
Generally speaking, these are articles written by experts in their field. These articles are reviewed and scrutinized by other experts in the same field (peers) before the article is accepted for publication. The idea is that only the best, most scholarly information is presented in these kinds of articles.

Remember--the databases may indicate a journal, e.g.: Nature, is peer-reviewed, but that editorial or news article published in Nature is not peer reviewed. Only the research articles are peer-reviewed.
