Is it Really
Everything that is copyrightable is not
In some instances organizations and individuals choose
not to copyright their work in order to encourage duplication and
distribution. Before 1976, copyrighted works had to be registered
and were required to carry a copyright notice. Lack of a copyright
notice indicated lack of copyright protection. A work published
without registration or without proper copyright notice
automatically entered the public domain. (Note: Due to treaty
agreements, works published outside the United States that would
have fallen under this may have have had their copyright restored
and may be protected.)
These requirements have been eliminated. Registration
was made optional in 1976 and, starting in March 1989, Congress
dropped the notice requirement. Absence of copyright notice is no
longer a reliable indicator of whether a work is protected.
