National Library Service for the Blind and Print Disabled

The National Library Service for the Blind and Print Disabled^[1] (NLS) is a free library program of braille and audio materials such as books and magazines circulated to eligible borrowers in the United States and American citizens living abroad by postage-free mail and online download. The program is sponsored by the Library of Congress. People may be eligible if they are blind, have a visual disability that prevents them from reading normal print, or a physical disability that keeps them from holding a book.^[2][3] Library materials are distributed to regional and subregional libraries and then circulated to eligible patrons.^[4] In total there are 55 regional libraries, 32 subregional libraries, and 14 advisory and outreach centers serving the United States and its territories: the District of Columbia, Puerto Rico, the U.S. Virgin Islands, and Guam.^[5]
