CC0 enables scientists, educators, artists and other creators and owners of copyright-protected content to waive copyright interests in their works and thereby place them as completely as possible in the public domain, so that others may freely build upon, enhance and reuse the works for any purposes without restriction under copyright.
In contrast to CC’s licenses that allow copyright holders to choose from a range of permissions while retaining their copyright, CC0 empowers yet another choice altogether – the choice to opt out of copyright and the exclusive rights it automatically grants to creators – the “no rights reserved” alternative to our licenses.
