Vancouver Referencing Guide: Personal Communications (interviews, letters, emails, conversations, lecture notes)

A guide to the Vancouver referencing style commonly used in the biomedical sciences

Personal Communications

Avoid using personal communication as a reference unless it provides essential information not available from a public source. This includes e-mails, discussion lists, lectures or lecture notes, interviews, letters, conversations.

If you decide you must use a personal communication, do not make it a formal numbered reference; instead give the details in the running text of your document. Check with your instructor that it is acceptable to use this type of source. Also, since this is “personal” and not public communication, you should obtain permission from the source.

Include the nature, date, and source/name of the person of the cited information, and use a term or terms to indicate clearly that no corresponding citation is in the reference list. Place the source information in parentheses in the text.
