In response to important changes in copyright law as the United States accommodates itself to the Berne Convention and develops means to take account of new technologies, this guide puts these changes in a form and context that will make sense to persons who are concerned about their rights under the law. New material in the fourth edition of this guide includes case law on databases and compilations, new provisions for copyrighting architectural designs and distributing software, the latest work on "look-and-feel" cases, the ongoing interpretation of the moral rights of creators implied in the Berne Convention, the implications of the Kinko's case, and new guidelines for off-air videotaping for educational use. Chapters in the guide are: (1) The Subject Matter of Copyright; (2) Ownership; (3) Transfers of Copyright; (4) Copyright Notice; (5) Registration of a Copyright Claim; (6) Rights in Copyrighted Works; (7) The Compulsory Licenses; (8) Infringement and Fair Use; (9) Works Created before 1978; (10) Tax Treatment of Copyrights; and (11) International Copyright Protection. Appendixes contain information on copyright notices, editions in the Library of Congress, registration of computer programs and databases, and warnings of copyright for use by certain libraries and archives.
