Understanding Free Cultural Works
Creative Commons provides a range of licenses, each of which grants different rights to use the materials licensed under them. All of these licenses offer more permissions than “all rights reserved.”
To help show more clearly what the different CC licenses let people do, CC marks the most permissive of its licenses as “Approved for Free Cultural Works.” When you apply these licenses to material you create, it meets the Freedom Defined definition of a “Free Cultural Work.” Free cultural works are the ones that can be most readily used, shared, and remixed by others, and go furthest toward creating a commons of freely reusable materials.
