CC Search is a tool that allows openly licensed and public domain works to be discovered and used by everyone. Creative Commons, the nonprofit behind CC Search, is the maker of the CC licenses, used over 1.4 billion times to help creators share knowledge and creativity online. CC Search searches across more than 300 million images from open APIs and the Common Crawl dataset.
