CreativeCommons.org is the official site for Creative Commons, which is an American non-profit organization devoted to expanding the range of creative works available for others to build upon legally and to share. The organization has released several copyright-licenses, known as Creative Commons licenses, free of charge to the public.
Use the tools found on Creative Commons tools to share your work. Free, easy-to-use copyright licenses offer a simple, standardized way to give your permission to share and use your creative work. Adopt one of the various CC licenses to share your work according to the conditions of your choice.
Creative Commons Licenses dictate whether a resource can be revised and remixed, as well as whether or not commercial entities can use it. The two most “open” licenses are CC By and CC BY– SA because they allow for revisions and remixes along with commercial and non-commercial use.
