One of the very unfortunate side effects of the Berne Convention Implementation Act of 1988 (and the reason I think it is gravely flawed) is that there is now no clear way, in the United States, for an author to deliberately place a work into the public domain. Previously deliberate publication without copyright notice was sufficient.
