Creative Commons licenses make it easier for authors and publishers to tell readers whether and how they can use copyrighted books, says Google Books Associate Product Manager Xian Ke.

You can grant your readers the right to share the work or to modify and remix it. You can decide whether commercial use is okay. Theres even a license to dedicate your book to the public domain.Books that have been made available under a CC license have been marked with a matching logo on the books left hand navigation bar.
