This collection consists of five series: general correspondence (1959-1975), minutes (1957-1975), news releases (1963-1974), organizational materials (1963, 1971-1974), and subject files (1955-1983). The bulk of the collection consists of subject files which are predominantly the records of committees and subcommittees of the Council; these are arranged alphabetically by the name of the subcommittee. Most, but not all, subcommittees issued reports which were published and distributed. Interfiled with the subcommittee records are the records of statutory committees which received Legislative Council staff assistance. These include, for example, the Administrative Code Committee, the Capitol Building and Planning Committee, the Coal Tax Oversight Committee, the Montana Salary Commission, the Revenue Oversight Committee, and the Water Resources Oversight Committee. Also interfiled with the subcommittee subject files are studies and reports conducted by the Council, not by a subcommittee; these are arranged alphabetically by the subjects of the studies. Maps, photographs, and printed materials have been transferred to the Library Map Collection, the Photo Archives, and the Library respectively.
