1. Say if I take an ebook from Gutenberg and post it on my website or sell it as an ebook, would it be illegal if someone else had earlier taken the same book from the public domain and copyrighted it (provided you can copyright public domain works)? I was just wondering how one goes about verifying such things.
2. A number of online resources have been mentioned on the use of Public domain. I was wondering if there are any offline public domain materials that can be used and if so where could I get it?
I would appreciate your guidance in this matter.
