The Warner Library became a reality because of the generosity of local residents Worcester Reed Warner and his wife, Cornelia Blakemore Warner. In the late 1920s they undertook to have a library built as a gift to the community. It serves both villages of Tarrytown and Sleepy Hollow and a diverse community with a strong Hispanic population. The staff provide a wide variety of programs, including cooking, art, history, technology, senior care, and entertainment.
