Copyright and Business License Needed for a Public Domain Book in US?
I'm new to selling on Lulu and new to these forums. Does anyone know if:
1) A copyright is needed in order to sell a public domain book? Also do I need to have the copyright information printed within the book?
2) In the US, at what point would I need a business license to sell books? Is there a profit cap? How does this work?
Thank you very much for any help with these!
