The Friends of the Belmont Library are a non-profit organization that brings together people who view their local library as a treasury of knowledge, information, and entertainment.

Friends of the Belmont Library is a tax deductible, charitable organization whose mission is to promote community support and use of the Belmont Library. Since its inception in 1974, Friends of the Belmont Library has raised money through membership and book sales to sponsor library programs and cultural events for children and adults. Membership dues also pay for materials and equipment not supplied by the library budget. During the construction of the new Belmont library, Friends of the Belmont Library raised over $370,000 for furnishing the new library. The money was used for a $160,000 state-of the art sorting machine, check-out counters, and computers.
