How do I cite a personal interview when the interviewee wishes to remain anonymous?

If a person you are interviewing wishes to remain anonymous, do not create a works-cited-list entry for the interview. Instead, indicate in an endnote that the source is a personal interview and provide any relevant details such as the method of communication (e.g., phone, e-mail, text message, in-person meeting) and the date on which the interview took place.
