Organized in 1948 by civic-minded residents, the Bellmore Memorial Library started in one room of an old wooden schoolhouse with 150 volumes borrowed from the NY State Library and a handful of donated books. Over 65 years later, the Bellmore Memorial Library is a vibrant community center, serving the information, cultural, and recreational needs of more than 16,000 residents. In 2015, the library joined with the local Chamber of Commerce and the North Bellmore Public Library to form the Bellmore Historical Association (BHA). Artifacts in the BHA collection are currently preserved and archived at the Bellmore Memorial Library.
Bellmore Historical Association at the Bellmore Memorial Library is a member of the Long Island Library Resources Council.
