Keep in mind that the pre-1989 requirements for copyright notice were highly formalistic and, other than a few enumerated exceptions, required these three elements:
- "The symbol © or the word 'Copyright' or the abbreviation 'Copr.' or an acceptable variant such as "(c)";
- "The year of first publication for the work"; and
- "The name of the copyright owner, or an abbreviation by which the name can be recognized, or a generally known alternative designation of the owner."
If just one of these elements is omitted, the work is deemed to be published without notice and is not eligible for copyright protection. Neither the year nor a copyright symbol appear anywhere on the dust jacket.
