Creative Commons License

several copyright licenses released by Creative Commons, a U.S. non-profit corporation founded in 2001. Many of the licenses, notably all the original licenses, grant certain "baseline rights", such as the right to distribute the copyrighted work without changes, at no charge. Some of the newer licenses do not grant these rights. Creative Commons licenses are currently available in 43 different jurisdictions worldwide, with more than nineteen others under development.
