Google Books helps authors and publishers discover new audiences for books they've made available for free under Creative Commons (CC) licenses. Rightsholders who want to distribute their CC-licensed books can choose to grant the right to download, use, share, modify and remix their work via Google Books. You can decide whether commercial use’s okay. There's even an option to dedicate your book to the public domain. If you're a rightsholder interested in distributing your CC-licensed book on Google Books, you’ve a few different options. If you're already part of Google Partner Program, you can make your book available under CC by updating account settings. If not, you can sign up as a partner. You can select from one of seven Creative Commons options, and usage permissions’ll vary depending on the license.
