There are thousands of public domain ebooks that are being sold on various websites . Can anyone anyone shed some light into this ?
The reason i'm asking this question is that I'm planning to translate some public domain books in my language and distribute them for free (me and some other volunteers). Can anyone tell me if there are any European Union laws that would prohibit this ?
