"Mandatory Deposit for Works Published in the United States."

+ Publication of a work can affect the limitations on the exclusive
rights of the copyright owner that are set forth in Title 17, Chap 1
of the law.

+ The year of publication may determine the duration of copyright
protection for anonymous and pseudonymous works (when the author's
identity is not revealed in the records of the Copyright Office) and
for works made for hire.

+ Deposit requirements for registration of published works differ from
those for registration of unpublished works. See discussion on
"Registration Procedures."

+ When a work is published, it may bear a notice of copyright to
identify the year of publication and the name of the copyright owner
and to inform the public that the work is protected by copyright.
Copies of works published before March 1, 1989, must bear the notice
or risk loss of copyright protection. See discussion on "Notice of
Copyright" below.

NOTICE OF COPYRIGHT

The use of a copyright notice is no longer required under U. S. law,
although it is often beneficial. Because prior law did contain such a
requirement, however, the use of notice is still relevant to the
copyright status of older works.
