Creative Commons licenses provide an easy way to manage the copyright terms that attach automatically to all creative material under copyright. Our licenses allow that material to be shared and reused under terms that are flexible and legally sound. Creative Commons offers a core suite of six copyright licenses. Because there is no single "Creative Commons license," it is important to identify which of the six licenses you are applying to your material, which of the six licenses has been applied to material that you intend to use, and in both cases the specific version.
All of our licenses require that users provide attribution (BY) to the creator when the material is used and shared. Some licensors choose the BY license, which requires attribution to the creator as the only condition to reuse of the material. The other five licenses combine BY with one or more of three additional license elements: NonCommercial (NC), which prohibits commercial use of the material; NoDerivatives (ND), which prohibits the sharing of adaptations of the material; and ShareAlike (SA), which requires adaptations of the material be released under the same license.
