The McClurg Museum has been the home of CCHS since 1951. The Chautauqua County Historical Society was founded in 1883, making it one of the oldest societies in Western New York State. Since its inception, CCHS has been collecting and preserving the significant history of Chautauqua County. Its mission is to foster an interest in and knowledge of the history of Chautauqua County through the collection, preservation and interpretation of objects and archives of local significance. The Research Library contains several important collections, including the Elial T. Foote collection, the Cushing family papers, the Albion W. Tourgee collection and the John O. Bowman photographic collection. Genealogists reference local history files, including family histories and Civil War documents.
The society maintains an active schedule. Members enjoy quarterly programs, special receptions, museum exhibits and a free subscription to TimeLines, the society's award-winning newsletter.
