If you are adapting an existing open textbook or creating a new one, you may want to find additional resources to use. Ideally, content licensed with a CC-BY license provides the most flexibility for reuse, so we recommend trying to find content for reuse with that specific CC-BY licenses. If you are planning to make adaptations to the resource, you will want to avoid any CC material that has the -ND (No Derivative) attribution as this content can be reused, but not adapted.

If you are looking for Creative Commons licensed content, you can try the following services and search engines.

• Creative Commons’ Content Directories: a list of organizations and projects powered with Creative Commons (CC) licenses.

• Search  in The Commons on Flickr launched January 16 2008 in partnership with The Library of Congress. Participants are cultural heritage institutions who share publicly held photography collections. There are “no none copyright restrictions” on the photographs in this collection.
