The collection is broken into two sub-groups: Tim Babcock and Betty Babcock.

The collection consists of five accessions, two donated by Governor Babcock and one donated by Randy O. Carlson, one donated by the decedents of Tim and Betty following their passing, and one donated by Betty. The Governor's donations contain subject files (1965-1968), including correspondence, press releases, speeches, and financial records from his two terms as governor and also some personal papers covering various business and personal interests of Tim (1968-1995); and six scrapbooks (1961-1968) containing newspaper clippings, certificates, and photographs, compiled by the Governor's wife and staff and presented to him as a gift. The Carlson donation consists of records of Dave Holliday, the Governor's administrative assistant, and includes correspondence, press releases, speech material, and subject files on such topics as a sales tax and Republican political organizations. There also is a small amount of personal material regarding Holliday's work for the Intermountain News Network. The collection also contains a reel-to-reel audio tape of Babcock's campaign ads (MM29). The Babcock family donation consists of subject files and speeches from Tim Babcock created/collected during his terms as governor (1962-1968), as well as business records (legal, financial, maps) and subject files relating to his various diplomatic and philanthropic activities (1961-1995).

Betty Babcock's donation consists of her papers (correspondence, subject files, notes, press releases, legal files) from the 1972 Montana Constitutional Convention and correspondence and subject files she collected and created for the 44th Legislative Session of Montana (1975).
