An article is a piece of writing found in a periodical or serial -- commonly known as magazines, newspapers, and journals. Articles are a way to up-to-date information (based on when material was published).
In order for an article to be considered "scholarly" it is vetted and approved by other scholars in the field (hence peer reviewed).

Scholarly articles are found in peer review journals. You can find scholarly articles at Yale Library using:
