The document discusses Creative Commons (CC), a non-profit organization that provides legal tools to allow for sharing, reusing, and remixing creative works while still providing attribution to the original creators. CC licenses allow individuals and creators to specify certain conditions for using their works, such as requiring attribution, prohibiting commercial use, requiring derivative works to use the same license, or prohibiting derivatives. This increases the amount of cultural, educational, and scientific content available in the commons for free and legal use, repurposing, and remixing while still protecting creators' rights.
