Credible sources earn your trust by relying on evidence to support claims. You can trust that the ideas expressed are the author’s (or are attributed to the actual author) and the ideas are supported by evidence. The definition of a “credible source” may vary depending on the discipline and the purpose of the writing. If in doubt, ask your instructor.
