he 1976 revision was undertaken for two primary reasons. First, technological developments and their impact on what might be copyrighted, how works might be copied, and what constituted an infringement needed to be addressed. Second, the revision was undertaken in anticipation of Berne Convention adherence by the U.S. It was felt that the statute needed to be amended to bring the U.S. into accord with international copyright law, practices, and policies. The 1976 act preempted all previous copyright law and extended the term of protection to life of the author plus 50 years (works for hire were protected for 75 years). The act covered the following areas: scope and subject matter of works covered, exclusive rights, copyright term, copyright notice and copyright registration, copyright infringement, fair use and defenses and remedies to infringement. With this revision, for the first time the fair use and first sale doctrines were codified, and copyright was extended to unpublished works. In addition, a new section was added, section 108, that allowed library photocopying without permission for purposes of scholarship, preservation, and interlibrary loan under certain circumstances.
