Subsequent to Betsy Devine's interview, Selberg was interviewed several other times. The file attached below comes from the February 12, 1991 issue of the "Princeton Packet", a weekly newspaper in Princeton.
The wide-ranging interview done by N. Baas and C. Skau in November 2005 can be found here (in both English and Norwegian).
A third interview, conducted in June 1999, can be found in the book, Fascinating Mathematical People: Interviews and Memoirs, ed. by D. Albers and G. Alexanderson, Princeton University Press, 2011, pp.254--273.
