The ORIGINAL is in the public domain, and he would have no rights to
restrict anybody else from scanning and distributing the original.
HOWEVER, even the flimsiest claims of enhancement could enable a copyright
claim for a "derivative work", and protect copies of HIS scans.
Project Gutenberg ran into that in their early days. They thought that
they could scan modern printings of public domain literature, and
distribute those as images. But, although the WORDS are public domain, by
dint of their typography, the modern printers have claim to those images.
Whether you could OCR a modern printing to get back to the original
[public domain] text now might run afoul of DMCA, but not any rational
copyright law.
Derivative work copyright will, of course, not stand up if the original
was copyrighted and original copyright holder makes a claim of
infringement.
Copyright just doesn't work like that though...the original copyright
holder /still/ holds the copyright, no matter if someone scans it to a
PDF or makes a xerox copy. Under US copyright law, they cannot even
make a "sweat of the brow" argument as that is not an accepted legal
argument under US copyright law.
Correct, that was settled decades ago. There is also the possibility
that the original document may be in the public domain, either because
no claim of copyright was made originally and publication was before
copyright became automatic (1978) or because copyright applied
originally but was not renewed when it came up for renewal. For
example, I have a Linotype typecasting handbook from around 1940; it's
in the public domain because its copyright was due for renewal in 1958
and a search of the records shows that no renewal was done.
and, of course, there are those who claim "abandonware" as if it were a
legal process.
"I couldn't find the author" (not in top 5 hits on Google?),
"therefore it is no longer subject to copyright".
Expiration now takes a long time.
Walnut Creek CD-ROM had to recall a bunch of discs, when they found out
that Edgar Allen Poe's estate still had a valid copyright claim to some
works.
There have even been incidents where people have altered/removed copyright
notices in order to try to claim that an object was public domain based on
their having received a copy without [surviving] copyright notice.
Wikipedia has a lot of information on this because they are quite picky
about copyright, so they have an excellent database of all the relevant
rules (not just US ones but other countries as well).
And there are arguments to this day about just how retroactive the Berne
Convention is/was/should be. It relaxed the requirements on copyright
notices.
One of the aspects that Intel lost in the Intel V NEC trials had to do
with procedural issues on copyright NOTICES.
