Includes Records dated 1934-1978, of the Niagara Frontier Chapter of the American Civil Liberties Union and its predecessors, including correspondence, minutes, case files, news releases, background files, photographs, newspaper clippings and other materials. The activities of the chapter were largely confined to the city of Buffalo and nearby Erie and Niagara Counties, but occasionally the chapter was involved in cases and issues in other parts of Western New York. Also Included are records of the Upstate New York Division which document its efforts to build ACLU membership in the "Southern Tier" of New York State and particularly in Ithaca, N.Y. in the early 1960's. Correspondence documents the organizational life of the chapter both internally and in its relations with the national ACLU (including correspondence with Roger Baldwin) and later with the NYCLU. Letters from people in the local community congratulating or taking issue with the ACLU's position on various issues document public attitudes towards civil liberties. Other letters, primarily but not exclusively in the case files, seek the ACLU's assistance on a variety of legal issues. Complaint and case files document the work of the ACLU in numerous issues from Indian rights in the 1930's to prison reform in the 1970's. Also included are materials on legal cases. The earlier materials are generally filed by subject, e.g. "academic freedom" or "freedom of speech". Beginning in the mid 1960's, there are more extensive files arranged by personal name, with most case files dating from circa 1969-1975. Legal materials from circa 1976-1977 are unorganized.
