The Allied Arts Council of Southern Nevada (AACSN) Records are comprised of the organizational records of the Allied Arts Council, a Las Vegas, Nevada-based non-profit organization that promoted the arts and cultural life in Southern Nevada from 1971 to 1999. Materials include meeting minutes, financial records, correspondence, membership information, publications, event information, project files, photographs, audio cassettes, VHS, and U-Matic tapes.

The collection, 1949 to 2006, was compiled by Clifford Olsen, a containment physicist at the Nevada Test Site (NTS). It consists of research notes and working papers written by Olsen and other scientists, publications, epoxy aggregate samples, work-related correspondence, nuclear-test-event data, and interviews conducted by Olsen with work colleagues involved with the NTS.
