Popular: Publications intended for a general audience of readers, they are written typically to entertain, inform, or persuade. Popular sources help you answer who, what, when, and where questions and are essential for finding information about current events or issues.

Scholarly: Publications intended for use in support of conducting in-depth research, often containing specialized vocabulary and references to sources. The content has been reviewed by academic peers to ensure the reliability of methods used and the validity of findings.

Trade: Sources intended to share general news, trends, and opinions among practitioners in a certain industry or profession.
