claimed in Chapters 7-10, exclusive of U. S. Government maps

Copies of works published before March 1, 1989, that consist primarily
of one or more works of the U. S. Government _*should*_ have a notice
and the identifying statement.


-=Unpublished Works=-

The author or copyright owner may wish to place a copyright notice on
any unpublished copies or phonorecords that leave his or her control. _

-=Omission of the Notice and Errors in Notice=-

The 1976 Copyright Act attempted to ameliorate the strict consequences
of failure to include notice under prior law. It contained provisions
that set out specific corrective steps to cure omissions or certain
errors in notice. Under these provisions, an applicant had 5 years after
publication to cure omission of notice or certain errors. Although these
provisions are technically still in the law, their impact has been
limited by the amendment making notice optional for all works published
on and after March 1, 1989. For further information, request Circular 3
