The Westchester County Historical Society’s library has a wide variety of primary and secondary sources on the history of the county and on all of the cities, towns and villages it comprises, as well as on the people who have lived in Westchester for the past 400 years. Among the many materials in the library are books, pamphlets, newspapers, manuscripts, works of art, photographs and ephemera. Presented here are samples from the collection, some chosen for their historic value and others for their visual interest.
