To create a reference to an interview you undertook, your reference should include the name, position, and institution (if relevant) of the interviewee, followed by the location and date in brackets.
Format: Name, Position, Institution (location, date)
Example: Interview with Irene Kull, Assistant Dean, Faculty of Law, Tartu University (Tartu, Estonia, 4 August 2003)
If the interview is conducted by someone else, the reference should start with the names of the interviews and then follow the same format.
Example: Timothy Endicott and John Gardner, Interview with Tony Honoré, Emeritus Regius Professor of Civil Law, University of Oxford (Oxford, 17 2007)
There is no change in format between a footnote reference and a bibliography entry.
