Although most of Hansen's career was spent as an educator, the collection reflects only his legislative work. His interest in education is revealed, however, in the reference materials on education which are present. Also included are correspondence, 1965-1969, with a separate file dealing with environmental control of pesticides, 1967-1968; voting records, 1965-1967; campaign materials, 1964-1968; and miscellany, 1965-1969.
