About JJML

Our History

Sag Harbor’s John Jermain Library was commissioned and built in 1910 by Margaret Olivia Slocum Sage in memory of her grandfather, Major John Jermain, as a gift to the people of Sag Harbor. It was named a contributing structure to the Sag Harbor Historic District in 1973; a light-filled fully-accessible addition, which doubled the space of the building, opened in 2016.

Our Place in the World

The library, a member of the Suffolk Cooperative Library System, provides free access to books, e-books, audiobooks, media, local history materials, museum passes, WiFi and public computers, as well as a wide range of cultural programming including storytimes, art exhibits, language classes, book clubs, movies and concerts.

The library’s service area is contiguous with the Sag Harbor Union Free School District and includes the incorporated Village of Sag Harbor, the incorporated Village of North Haven, Noyac, and the Mount Misery, Eastville, and Baypoint neighborhoods. John Jermain is a key stakeholder in the Main Street business district, and a founding member of the Sag Harbor Cultural District.

Our Goals

The John Jermain Memorial Library seeks to be a center of reliable, up-to-date information, for all the people the Library serves, and to support the educational, civic, cultural, and recreational activities of the community by

  1. Aiding the individual’s pursuit of self-education and research, pleasure, and the creative use of leisure time, while employing the most efficient library technology available;
  2. Promoting ease of access to the library, books, and other library materials in general, both locally and throughout the county;
  3. Maintaining a pleasant environment in an atmosphere of helpfulness;
  4. Providing library service in conformity with the Library Bill of Rights as adopted by the Council of the American Library Association.
