This document discusses open educational resources (OER) and Creative Commons (CC) licensing. It explains that OER allow for access, sharing, adaptation, and derivation, and the more permissions granted, the more open the resource. CC licenses work with copyright to grant certain permissions for uses of a work without requiring permission. The CC BY license is recommended as it allows the most freedoms while still requiring attribution, and is compatible with all other CC licenses. Different CC licenses are suited for different purposes depending on whether derivatives or commercial use is allowed.
