Creative Commons licenses provide an easy way to manage the copyright terms that attach automatically to all creative works under copyright. Our licenses allow those works to be shared and re-used 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 work, and which of the six licenses has been applied to a work you intend to use.
All of our licenses require that users provide attribution (BY) to the original creator and licensor (where those are different) when the content is used and shared. Some licensors choose the BY license, which conditions reuse only on that condition. The other five licenses combine BY with one or more of three additional conditions: NonCommercial (NC), which prohibits commercial use of the work; NoDerivatives (ND), which permits reuse provided the work is not modified; and if modifications are allowed, ShareAlike (SA), which requires modified works be released under the same license.
CC licenses may be applied to any type of work, including educational resources, music, photographs, databases, government and public sector information andmany other types of creative content. The only categories of works for which CC does not recommend its licenses are computer software and works that are no longer protected by copyright or are otherwise in the public domain.
