Not all, but many creators of OERs choose to apply licenses indicating how others can use their work. Most commonly used are Creative Commons licenses, or a set of statements that indicate the author's wishes when it comes to citing their work, using it for commercial purposes, adapting it, and redistributing it. The OER community encourages open licenses to allow OERs to grow and improve over time while being used in local settings.

This license is often compared to “copyleft” free and open-source software licenses. All new works based on yours will carry the same license, so any derivatives will also allow commercial use. This is the license used by Wikipedia and is recommended for materials that would benefit from incorporating content from Wikipedia and similarly licensed projects.
This license is the most restrictive of our six main licenses, only allowing others to download your works and share them with others as long as they credit you, but they can’t change them in any way or use them commercially.
