Citation, Documentation of Sources
Q. How would one document an interview?
A. Please see CMOS 14.219: “Unpublished interviews are best cited in text or in notes, though they occasionally appear in bibliographies. Citations should include the names of both the person interviewed and the interviewer; brief identifying information, if appropriate; the place or date of the interview (or both, if known); and, if a transcript or tape is available, where it may be found. Permission to quote may be needed; see chapter 4.” Here’s an example:
8. Benjamin Spock, interview by Milton J. E. Senn, November 20, 1974, interview 67A, transcript, Senn Oral History Collection, National Library of Medicine, Bethesda, MD.
