Peer review is the process by which, prior to publication, research articles are evaluated by a group of experts in the field (peers).
Scholarly journals are publications which report original research to other academics within a specific discipline. Articles which appear in scholarly journals are typically, but not always, subject to peer review prior to publication.
Newspaper articles, Newsweek, etc. are not primary literature. .
Journal databases that we suggest in our Subject guides or course guides will be the most efficient places to start for finding primary literature for your course assigments. Subject guides for the sciences are the tabs at the top of the Science Library home page.
Some databases, such as Scopus, provide access to primary literature and review articles almost exclusively. We try to give you a clue about this when we describe the database.
