Academic sources (also known as scholarly sources) often include peer-reviewed (or refereed) research articles. These are articles that have been read, evaluated, and approved for publication by scholars with expertise and knowledge related to the article’s subjects and contents. Peer-reviewing helps insure that articles provide accurate, verifiable, and valuable contributions to a field of study.
Journals that use the process of peer-reviewing to select articles for publication are often called “peer-reviewed” or “refereed” journals. Peer-reviewed journals can also include materials like letters to the editor, book reviews, and news briefs that have not been peer-reviewed.
