This wide-ranging, retrospective interview with Selberg was done in June 1989 at IAS; the interviewer was Betsy Devine. It is currently unpublished, and is part of the "Oral History Project" at IAS.
The copy found in Selberg's office was printed in 1990. On the basis of this and the short note that Betsy Devine attached to part 2, it seems likely that this version was proofread by Selberg.
