2 U.S.C. § 135a — National library service for the blind and print disabled

(a) Accessible materials and reproducers. (1) In general: The Librarian of Congress may provide to eligible people — U.S. residents (including in the states, insular possessions, and the District of Columbia) and U.S. citizens living abroad — (A) literary works in braille, on audio recordings, or in any other accessible format; (B) musical scores, instructional texts, and other specialized music materials in any accessible format, to further education, jobs, and culture; and (C) the players or reproducers needed to use those formats. (2) Ownership: Anything provided is on loan only. It stays the property of the Library of Congress. (b) Lending preference. In lending these items, the Librarian must always give preference to (1) the needs of blind and visually disabled people, and (2) the needs of eligible people honorably discharged from the U.S. Armed Forces. (c) Network. The Librarian may contract or otherwise arrange with public or nonprofit libraries, agencies, or organizations to serve as local or regional centers that circulate these items. (d) International service. The Librarian may provide the literary-works and music items to authorized entities in a country that is party to the Marrakesh Treaty, but only if delivered to those entities online, not physically. The Librarian may arrange with those entities to deliver the items to eligible people in their countries, in any accessible format, consistent with section 121A of title 17. (e) Contracting preference. In buying and maintaining these items, the Librarian must give preference to nonprofit institutions or agencies mainly concerned with blind and other physically disabled people — without needing to follow the usual procurement rule in section 6101 of title 41 — whenever, considering all the circumstances and needs, the Librarian finds their prices fair and reasonable. (f) Regulations. The Librarian must issue regulations for services under this section, in consultation with eligible people and authorized entities. These regulations must include procedures an individual can use to prove they are an "eligible person." (g) Definitions. "Accessible format," "authorized entity," and "eligible person" have the meanings given in section 121 of title 17. "Marrakesh Treaty" has the meaning given in section 121A of title 17. This section itself does not define these terms. (h) Authorization of appropriations. Congress may appropriate whatever sums are necessary to carry out this section.
