All books initially copyrighted in the US from 1964 through 1977 have had their copyrights automatically renewed (by law) and the copyrights are still in force. The initial copyright term was 28 years; the renewal was for 67 more years.
Until 1989, a published work had to contain a valid copyright notice to receive protection under the copyright laws. But this requirement is no longer in force â works first published after March 1, 1989 need not include a copyright notice to gain protection under the law.
