Be careful. Bo's post is correct right up until the end. A publisher's
edition of an old work may still be protected by copyright law to some
extent--even though the original work is in the public domain. If the
publisher added any creative elements to the work (anything from
explanatory notes to new or different musical notation), the publisher
is the author of those added elements, and those added elements would be
copyrighted as if it was new work of the publisher (95 years from
publication, in the U.S., I believe).
The original work would still be in the public domain. The trouble,
however, can be in determining what is the original work and what is the
new added elements. Because almost all publishers add something to
works they publish, wholesale photocopying of a publisher's edition is
very risky.
Take an easy example. In high school, we read some Shakespeare plays
with quite extensive footnotes to explain things (and I still didn't
understand most of it!). Although Shakespeare's works are in the public
domain, I could not have legally copied the book we read, because it had
the publisher's annotations in it. I could have, however, hand-copied
the actual Shakespeare work, and then distributed it as I wanted.

Under current law (US and International), since Kopprasch is dead, lo
these many years, the copyright on his exercises has expired. Insofar
as BH did not create the original work but merely published it, and
regardless of any assignment that Kopprasch may have made to them,
their edition is in the public domain.
