On October 26, 1951, the Regents granted the Andes Public Library Absolute Charter as a municipal library.  In 1973, the library entered into a contract with the Town of Andes to provide services to all Town residents.  In 1984, the library was designated a historic building as part of the Historic District in the Village of Andes and included on the NYS and Federal Registers.

The free use of the building and its maintenance are costs of the municipality.  The costs of personnel, the collection, necessary computers, fax, copy machines, furniture, as well as the insurance on these, have been borne by the library with the support of donations, fundraisers, and cash from the village and town budgets.
