  • The “outdated sources” myth - APA Style

    In this series, we will look at common APA Style misconceptions and debunk these myths one by one. We often receive questions about whether sources must have been published within a certain time frame to be cited in a scholarly paper. Many writers incorrectly believe in the “outdated sources” myth, which is that sources must have been published recently, such as the last 5 to 10 years. However, there is no timeliness requirement in APA Style guidelines (as defined in the Concise Guide to APA Style, Seventh Edition and Publication Manual of the American Psychological Association, Seventh Edition).
