This collection consists of records collected and created by Mignon Waterman prior to, during, and after her time as a Senator in the Montana state legislature (1990-2002). The series represented in the collection - correspondence, financial records, subject files, miscellany, and clippings - are organized by sub-group in keeping with the original organization imposed by Mrs. Waterman. As such, the collection is divided into five sub-groups: "School Board Years and Mental Health Initiatives" (1978-2000); "Under-funded School Law Suit" (1978-1990); "Project Excellence, School Accreditation Standards" (1987-1989); "Senate Papers" (1990-2004); "Congressional Race - 1996" (1996). The collection is primarily composed of subject files, with scattered correspondence written to Mrs. Waterman from her constituents. The addendum consists mainly of Mignon's daily planners (1975-1996). Planners reflect Mignon's dialy meetings.
