The Carl T. Hayden Papers consist of personal and political correspondence, newsclippings, speeches, legislation, congressional and senatorial files, research notes, printed matter and memorabilia dating from 1851 to 1979. The bulk of the collection documents Hayden's activities as an United States Senator from Arizona from 1940 to 1968.

The Carl T. Hayden Photograph collection houses 2,431 photographs documenting Carl T. Hayden and the extended Hayden family.

The Dorothy Parker Papers contain publications, transcripts, documents, a student-published yearbook (The Redskin), and 28 photographs. Although the collection dates from 1976 to 1991, the bulk of the materials were created in 1990 and 1991 and document the closing of the Phoenix Indian School and the subsequent archaeological study of the site.
