The Belmont Library was establishedin 1893 and originally housed in the back of a store on Main Street. A few years later, the library was moved into the upstairs of the Fire Department Hose House where it shared quarters with the Selectmen's Office.
In 1927, the owners of the Belmont Hosiery Company, George E. Duffy and Walter E. Duffy, made a gift to the town of a new Library Building. Architects were Wells and Hudson and the style chosen was Colonial Revival. The Hose House was moved to another site and the current Library building was erected. On February 10, 1928, the new Library was dedicated. Not only did the Duffy brothers grant the town with a new building, but they also gifted funds to maintain the building into the future. Furthermore, the brothers purchased a beautiful tall clock that had been made by clockmaker Elisha Smith of Sanbornton for the Library, which is still there today.
