A registration by the author or his heirs (or their authorized agent) in the U.S. Copyright Office that renews for a second term of 67 years a copyright originally registered prior to January 1, 1978. Works originally copyrighted prior to 1964 that were not renewed in their 28th year of copyright have fallen into the public domain. Works originally copyrighted between 1964 and 1977 are automatically renewed by statute, regardless of whether a renewal registration is made for them. See AUTOMATIC RENEWAL. The terms of copyright for works written on or after January 1, 1978 are generally the life of the author plus 70 years or 120 years from its creation (whichever comes first).
