Include the author, date, title (in italics) and the file format in brackets after the lecture title (e.g. PowerPoint slides, Word document). If it is an online source, include "Retrieved from" and provide the URL

The APA recommendations are not as helpful, but here is the answer straight from the source:

"The PowerPoint question is a classic one here at Style Expert headquarters. ... If the presentation was seen during a lecture or meeting and cannot be retrieved by the audience of your paper, it’s a personal communication, which means that no reference is needed, but it should be cited accordingly."

Following the advice from the APA style blog, see 6.20 Personal Communications on page 179 of the American Psychological Association (Ed.). (2010). Publication manual of the American Psychological Association (6th ed). Washington, DC:
