(a) General. This section prescribes the classes of copyrighted works for which the Librarian of Congress has determined, pursuant to 17 U.S.C. 1201(a)(1)(C) and (D), that noninfringing uses by persons who are users of such works are, or are likely to be, adversely affected.

An eligible library, archives, or museum may make each copy of such lawfully owned and preserved work available to different users simultaneously. This provision does not permit an eligible library, archives, or museum to make multiple, simultaneous copies of the same copy of a work for the purposes of providing users access to the work.
(21) Computer programs that operate 3D printers that employ technological measures to limit the use of material, when circumvention is accomplished solely for the purpose of using alternative material and not for the purpose of accessing design software, design files, or proprietary data.
