Commercial use under the Creative Commons License

OpenStax has published books under both CC BY ( https://creativecommons.org/licenses/by/4.0/) and CC BY NC SA ( https://creativecommons.org/licenses/by-nc-sa/4.0/) licenses. While both licenses allow for remixing and adapting the book's content in any medium or format, there are differences between how content can be distributed under each license. This article will explain those differences and show you where to find attribution and licensing information for your book.

CC BY Content

Content from books with a CC BY license can be used or redistributed commercially provided credit is given to OpenStax. If you are redistributing all or part of an OpenStax book in print or digital format, you must include an attribution on every physical page that connects the reader to the free format of their OpenStax book.

For your convenience, we have provided pre-formatted attributions at the bottom of every page in our online books and PDFs.

Here's an example from our Anatomy and Physiology book:

CC BY NC SA Content

Content from books with a CC BY NC SA license cannot be used or redistributed commercially at a profit. This means, content from these books cannot be sold above the cost of printing. Like redistributed content in CC BY-licensed books, you must include an attribution on every physical page that connects the reader to the free format of their OpenStax book.

Locating the License for your Book:

You can find the license for your book at the bottom of its Details page on openstax.org following these steps:

1. Go to https://openstax.org/subjects

2. Click on the cover of the book you would like to use. This will take you to its Details page.
