Books

I'm planning to publish a book in the following months, but I'm not entirely sure if the procedure is the same for both copyrighted and copy-lefted books. If you hadn't guessed, I'm publishing one with the latter license (i.e. Creative Commons). I'm planning on using Lulu.com for this first book, but I was wondering if there are publishing houses which are friendly towards copyleft media, preferably based somewhere in Europe.

Any help or suggestion is greatly appreciated!
