Once something has been released into the public domain, then it is
free. I can use it to create a derivative work under my own copyright.
The derivative work can have very minimal changes such as simple
formatting. For examples look at any of the republished classic texts.
Note the copyrights on them. Also look at the GRASS project
Which was originally public domain from the Army and now exists in a GPL
version and in one or two commercial products.

I believe that once something is in the public domain, it can no
longer be copyrighted. Anyone who likes can attach any kind of notice
to it, but those notices have no effect because the original item is
in the public domain.
My understanding is that this state of affairs is one reason why the
Free Software Foundation refuses to distribute the source code for the
implementation of the Icon programming language: The authors (University
of Arizona) have placed the implementation in the public domain,
but the FSF distributes only material that is covered by the GPL.
