The Aztec Club records (1930-1998) contain financial records, mailing lists, constitutions, a club history, receipt books, meeting minutes, correspondence, and administrative files. The Aztec Club was formally organized in 1930 to "promote intellectual, social, and civic fellowship amongst its members" from the University of Utah and the Salt Lake City community.

The William Wallace Newby papers (1930-1971) consist of personal and professional materials concerning William Newby (1902-1977), a professor of biology at the University of Utah from 1927-1971. Included are biographical information, obituary notices, an oral history transcript, numerous hand drawn and reproduced illustrations, and literature and correspondence pertaining to the Aztec Club, of which Newby was president from 1965-1966.
