Scholarly (peer-reviewed) resources undergo review by experts in a field of study, who determine that the articles are objective and credible before they are published. Examples of peer-reviewed resources include articles in academic journals, collections of essays or anthologies.
Non-scholarly are published without review by experts. Non-scholarly resources range from a variety of types, such as websites and magazines, to newspapers and books. If you plan to use non-scholarly materials, ask your instructor beforehand, and use the CRAAP Test.
