How to cite and reference PowerPoints in APA Style?
If the PowerPoint is available to people via an open website (that is, not your password-protected course website) or by other public means, please use the usual APA rules to cite the resource. For example,
Lastname, A. (year, Month day). Title of presentation [PowerPoint presentation]. Retrieved from http://www.xxxxxx
In-text citation: (Lastname, year, p. X)
If, however, the PowerPoint is only available during the presentation or after via password-protected access (such as a RRU Moodle course site), please consider the presentation to be personal communication. Personal communication is a category of information that covers nonrecoverable information, and unless the PowerPoint presentation is available to the general public, it's nonrecoverable because your reader can't access the information. See "How do I cite or reference personal communication in APA style?" for more information.
If you're citing secondary information retrieved from the PowerPoint - that is, your instructor referenced someone else in the PowerPoint, and you're citing that secondary author - it's always best to check with the presenter to see where he/she got that information and cite the original, or failing that, see if a librarian can help you find the resource so that you're working with a primary source. Please contact the RRU librarians for assistance.
