UCLA Office of Intellectual Property & Industry Sponsored Research: All about copyright (link updated 1/3/18)

Copyright protection ... is automatic upon creation of a copyrightable work.  In other words, if you could have registered your copyright with the United States Copyright Office, but chose not to do so, you still own the work...  Copyright registration becomes necessary if you wish to file a legal action against someone who is infringing upon your copyright.

Copyright protection lasts for the life of the author plus an additional 70 years.

A work is only in the public domain if it is no longer under copyright protection or if it failed to meet the requirements for protection.  A work created solely by the U.S. government (e.g., DMV manual) is in the public domain.  To put a copyrighted work in the public domain requires an explicit written declaration by the parties involved.
