these corrective steps were not taken, the work went into the public
domain in the United States 5 years after publication. At that time
all U.S. copyright protection was lost and cannot be restored.

Error in Year

If the copyright duration depends on the date of first publication and
the year given in the notice is earlier than the actual publication
date, protection may be shortened by beginning the term on the date in
the notice. (For later date in the notice, see "Omission of Notice.")

Example: A work made for hire is created in 1983 and is first published
in 1988. However, the notice contains the earlier year of 1987. In this
case, the term of copyright protection would be measured from the year
in the notice, and the expiration date would be 2082, 95 years from
1987.

Error in Name

When the person named in the notice is not the owner of copyright, the
error may be corrected by:

1. Registering the work in the name of the true owner;

*or*

2. Recording a document in the Copyright Office executed by the person
named in the notice that shows the correct ownership. Otherwise,
anyone who innocently infringes the copyright and can prove that he
or she was misled by the notice and obtained a transfer or license
