I would like to announce you to http://dml.cz/
. There are PD-70 texts
available for Wikisource. Many of them are in German language, but some of
them also in the Czech language.
They are not sorted by a license, but I would say, those from the 19th
century will be probably PD-70. Also there is a good news, that they are in
PDF and it si possible to exploit it like a raw text, unfortunately Czech
laws, protects parties which created digital collections.
So if you are interested in some of the books, lets write a list of them and
I will try to figure out, if they are PD-70 for sure. Any idea? How to find
out when the author died? Then if they'll be founded PD-70, it would be
pleasure for me to negotiate with the library the possible release for
