It usually has been registered _as_ copyrighted, which automatically
registers the time when it enters the public domain.  At least that was
the idea before Mickymouse law lobbying started, with the result that at
least in the U.S., no works have entered the public domain due to
copyright expiry for something like the last 50 years.  The laws always
got extended in time to keep that from happening.

And more often than not, they have no formal way of transferring a work
(short of copyright running out) into the public domain, either.
