First understand the meaning of
Publication:
What is publication? By making the
work available to the public via issuing of copies, communicating
to the public, could be physical distribution / lending, in electronic form,
transmission, broadcasting, or vide any other medium. If you publish
without license, then this is NOT considered as publication. For Copyrights, either
the Work would be Published, or, Unpublished. If Published, you
need to mention its first date of publication and the territory where it was
first published, and the name of the Publisher, who could the Author himself/herself
(self-publisher). And if the work is unpublished, then no date of first
publication is needed.
The work when published, may not
be available in public as such, albeit, in which case you see for translation/publishing
rights/compulsory licenses etc. are acquired by the prospective publisher from the
owner/author itself, or, vide making petition to the Registrar of copyrights. Is
it Copyright free? Nope! Until the term of the copyright is expired,
or the author/owner has renounced its rights, or, certain government works, or,
dedicated works. Albeit the legal term of copyright takes decades
to expire!
