Abstract: Papers of Robert Kastenmeier, a longstanding Democratic member of the United States House of Representatives for Wisconsin's Second District, documenting his career in Congress (1959-1991). As a member of the House Judiciary Committee and Chairman of the Subcommittee on Courts, Civil Liberties, and the Administration of Justice, the papers reflect Kastenmeier's interests and work on copyright and patent laws, intellectual property rights, civil rights, civil liberties, the courts, criminal code, prison reform, and prisoners' rights. The papers also document Kastenmeier's involvement in the impeachment proceedings of Judge Harry E. Claiborne and President Nixon; and his leadership role in the Liberal Group and the Democratic Study Group. Included are correspondence files, bill files, publicity and press files, legislative and committee files, and campaign related materials (including sound, film and video recordings).
