Treasures from the Westchester County Historical Society Exhibit on Display at the Chappaqua Library

Posted on:

In celebration of the 150th Anniversary of the Westchester County Historical Society (WCHS), a digital exhibit featuring treasures from the WCHS collection is on view now at the library until April 2, 2024. A sampling of the Society’s vast holdings, the exhibit’s images are in a looped slideshow that reflects various eras and geographical areas of the county.


The eleventh oldest county historical society in America, WCHS is primarily a library and research center. The non-profit organization is located in the Westchester County Records Center in Elmsford, where the county’s public records and archives are also housed. The work of the professionally-run WCHS library falls into three categories: acquisition of new materials, processing, and preserving the library's collections and providing public access to those WCHS collections. Documents, maps, photographs, manuscripts, books and other materials have been collected since the inception of WCHS, the only history organization that is steward of materials representing all of Westchester. The collection of over a half million materials are preserved in 10,000 square feet of state-of-the-art, temperature controlled vaults, on shelves equivalent to the length of 215 football fields. WCHS continues to add new materials to the WCHS library by gift, purchase, and long-term loan.
