IMPACT OF COPYRIGHT ACT ON COPYRIGHT INVESTIGATIONS
---------------------------------------------------

On October 19, 1976, the President signed into law a complete revision of
the copyright law of the United States (title 17 of the United States
Code). Most provisions of this statute came into force on January 1,
1978, superseding the copyright act of 1909. These provisions made
significant changes in the copyright law. Further important changes
resulted from the Berne Convention Implementation Act of 1988, which took
effect March 1, 1989; the Copyright Renewal Act of 1992 (P.L. 102-307)
enacted June 26, 1992, which amended the renewal provisions of the
copyright law; and the Sonny Bono Copyright Term Extension Act of 1998
(P.L. 105-298) enacted October 27, 1998, which extended the term of
copyrights for an additional 20 years.

If you need more information about the provisions of either the 1909 or
the 1976 law, write or call the Copyright Office. For information about
the Berne Convention Implementation Act, request Circular 93, "Highlights
of U.S. Adherence to the Berne Convention." For information about
renewals, request Circular 15, "Renewal of Copyright." For information
about the Sonny Bono Copyright Term Extension Act, request SL-15, "New
Terms for Copyright Protection." Copies of the law are now $14.00 each.
