NLS at the Library of Congress
National Library Service (NLS) is a free braille and talking book library service. The NLS music collection, authorized by Congress in 1962, includes braille and large-print musical scores, recorded instructional materials, and recorded materials about music and musicians. All materials are circulated postage free, and some digital audio and ebraille materials are available for download. Any person eligible for NLS service is also eligible for NLS music services. However, while patrons receive most NLS services through the network of cooperating libraries, music materials are circulated directly to patrons from the NLS headquarters in Washington, D.C.
