The Copyright Office of the Library of Congress is proposing to amend its regulations to permit the Library of Congress to record unpublished radio and other audio and audiovisual transmission programs. The Copyright Office regulations already provide for the Library of Congress to obtain copies of unpublished television transmission programs, either by recording fixations or by demanding copies in the form of a transfer, loan or sale at cost. This revised regulation makes similar provisions for audio transmission programs and includes transmission programs made available by radio broadcasts and by digital communications networks such as the Internet.
