What are "peer-reviewed" journals?
A peer reviewed journal is a special type of publication. Before articles are published within these types of journals, they are sent by the editors of the journal to other scholars in the field ("peers"), often anonymously, to get feedback on the quality of the scholarship, review research methods, as well as relevance or importance to the field. The article may be accepted, often with revisions suggested, or rejected for publication.
Considered the most respected, researchers wish to have their works published in them. Many often have low acceptance rates.
