I am building an eBook reading service (paid) and I aim to distribute free classics available on Gutenberg Project. (at least for the start)
I have gone through all Gutenberg terms which allows me to do almost anything, but Gutenberg being limited to the US, it doesn't say much beyond that.
I just came to know that Gutenberg is banned in Germany, because of a lawsuit arising out of the situation that copyright expiry differs between Germany and the US (where Gutenberg is located).
My questions are:
Does this mean I cannot sell any books in Germany? Are there exceptions? (By selling I do not mean to sell one book for €xx - it is rather unlimited books per month sort of, but it is no different from selling)
Is there a central place to know how many years old books could be safe to publish, in every country?
Is there another thing that I am completely overlooking (beyond number of years passed since published / author died)?
If there is a safer, more copyright-free + generic source than Gutenberg to find such books?
If at all infringement occurs, what sort of difficulties could arise for me?
