Does Creative Commons collect or track works licensed under a CC license?
CC does not collect content or track works except by way of example. CC builds technical tools that help the public search for and use works licensed under our licenses and other legal tools. For instance, the CC Network allows creators and users to express their support for Creative Commons, and also provides a tool for creators to authenticate ownership of their works. CC also offers tools like CC Search and DiscoverEd to help the public discover works offered under Creative Commons licenses on the Internet. Moreover, because CC licenses are search-enabled, you can search for works by license type via search engines such as Google and Yahoo!.
