The Hanover Town Library (in Etna) has been named to the National Register of Historic Places. Founded in 1898, the library building was built in 1905 as the official town library for the Town of Hanover, hence its formal name; however, because of its location and the fact that it has traditionally served the Etna and Hanover Center communities, it has been nicknamed the "Etna Library." The Etna Library provides Storytime, Summer Reading Program, and other special programs for children. The Etna Library has about 8,000 items in its collection and it is open 28 hours a week. The "Libraries of Hanover" card may be used at both the Howe Library and the Etna Library. KnowHowe, the online catalog, includes collections and information from both libraries.
The Hanover Town Library will maintain an active presence in the community, providing services in a personal manner and preserving its historic building for future generations.
