Maybe I read through the thread too quickly. But while source material in the Public Domain is available for anyone to use, Can't individual's work done to format and present the PD material be copyrighted (or at least protected in some way)?
If not, how can Barnes and Noble publish various classic PD books with copyright notices in them?
