Cite the college class as a personal communication for an in-text citation. You will need the professor's name, the name of the class, the words "personal communication" and the date of the lecture. For example: (P. Jones, American Literature personal communication, March 13, 2007).
Keep your reference list free of personal communication citations. List personal communication in-text only.
Cite discussion within the college class by listing the name of the person involved in the discussion, such as a classmate, and the phrase "personal communication." If the discussion involves the entire class, don't include an author at all. Simply list the title of the course, the words "personal communication" and the date of the discussion. For example: (American Literature, personal communication, March 13, 2007).
