Papers consist primarily of personal papers of Charles Benton Power, including incoming correspondence (1881-1953), diaries (1929-1949), minor financial records and legal documents, school notes and records (1880-1893), subject files, miscellany, and clippings.

The Charles Benton Power Estate Subgroup (1953-1960) includes general correspondence of co-administrators Blanche Mares and C.M. Wall, court papers; financial records, and subject files.

There are family subgroups for Power's wife Mabel Larson Power, his son Benton Power, his daughters Jane Power Tobin and Margaret Power Drum Carrick, and for the Flanagan Family.

There are also business subgroups for T.C. Power and Brother, T.C. Power Company, Benton Group of Mines, Benton Hardware Company, Benton Transportation Company, Big Sag Land and Livestock Company, Faith Mining Company, Helena Building and Realty Company, Phoenix Development Company, and Unit Petroleum Company.

This collection inter-mingles closely with the Thomas C. Power Papers (MC 55). The two collections should be used together, as many subgroups appear in both collections. See "Seperated Materials" under the Administrative Information below.
