This collection is a subgroup (Office) of the Montana Office of the Governor records. The Montana Office of Budget and Program Planning is administered through the Governor's Office. Please see the primary finding aid for more Montana Office of the Governor records.

This collection is made up of eight series: general correspondence (1961-1978); interoffice correspondence (1967-1978); news releases (1961-1977); organizational materials (1971, undated); reports (1970, 1975); speeches (1969-1970); subject files (1962-1978); and miscellany (1969-1971, undated). The general correspondence is largely outgoing correspondence, and a substantial portion with the governor. The correspondence discusses agencies' budgets and requests, fiscal policy and procedures, relevant legislation, and special projects. The interoffice correspondence discusses similar topics. The news releases are few and concern news releases issued by other state agencies considered erroneous by the budget director, and the budget of Montana Highway Patrol. The organizational materials are agency charts and position descriptions. The reports are reviews of the agency's work for the fiscal year. The three speeches concern the general work of the agency and state revenue and budget agency policy. The subject files concern special studies which the Office of Budget and Program Planning undertook, usually in conjunction with other state agencies. One such study (files on which comprise about half of the total collection) is a study, coordinated by the Office of Budget and Program Planning and conducted with the Department of Social and Rehabilitation Services, the Office of the Superintendent of Public Instruction, the Department of Health and Environmental Sciences, and the Department of Institutions, of a proposal to deinstitutionalize the developmentally disabled. These files contain varied information on the treatment of institutionalized individuals and the attitudes of all levels of personnel in the various state departments. The miscellany series contains blank budget forms and some unidentified writings chiefly concerning taxes in Montana.
