Creative Commons licenses are a common open license, especially for scholarship and open educational resources (OER). Like other open licenses, they work within copyright and outline explicitly which rights the creator wishes to retain over their work. Creative commons licenses outline four central restrictions:
BY: Attribution. Users must attribute the original work and creator.
SA: Share Alike. Any edits must be shared using the same license as the original.
NC: Non-commercial. Users are not allowed to commercialize items. In other words, uses "primarily intended for or directed toward commercial advantage or monetary compensation” are prohibited.
ND: No derivatives. Users are not allowed to make any derivatives of the original work. In other words, edits and adjustments, including translations, are prohibited.
These restrictions combine to make 6 Creative Commons licenses:
Each license can be interpreted by thinking: "Users are allowed to do whatever they want with the work as long as they _______" where you fill in the blank based on the restrictions. So, for example, the CC BY-NC-ND license can be interpreted as "Users are allowed to do whatever they want with the work as long as they attribute the original creator/work (BY) and don't commercialize (NC) or make changes to the work (ND)."

Creative Commons licenses are the most commonly used open licenses for open educational resources (OER), which are freely accessible educational materials available with no-cost use, sharing, and editing without restriction. These additional permissions are often called the "5Rs":
To satisfy the 5Rs, all Creative Commons licenses except those with no-derivatives can be used. Those materials using no-derivatives (CC BY-ND and CC BY-NC-ND) are still considered open, but are not considered OER.
