► When there are two authors: Last name, first name, and first name, last name.
► When there are three or more authors: Last name, first name, et. al. (et al. means "and more" and indicates there are more than two authors).
► Many scholarly journal articles have a unique identifier called a DOI (digital object identifier). If you see a DOI on the article, use that at the end of your citation. If there is no DOI on the article or the record, that's fine; use the permalink or URL instead.
