What is Creative Commons? Creative Commons is a nonprofit organization
They work to increase the amount of creativity (cultural, educational, and scientific content) in “the commons” — the body of work that is available to the public for free and legal sharing, use, repurposing, and remixing.
CC provides free, easy-to-use legal tools
Their tools give everyone from individual creators to large companies and institutions a simple, standardized way to grant copyright permissions to their creative work. The Creative Commons licenses enable people to easily change their copyright terms from the default of “all rights reserved” to “some rights reserved.”
Some Rights Reserved
Creative Commons defines the spectrum of possibilities between full copyright and the public domain. From all rights reserved to no rights reserved. Their licenses help you keep your copyright while allowing certain uses of your work — a “some rights reserved” copyright.
CC Licenses work alongside copyright
Creative Commons licenses are not an alternative to copyright. They work alongside copyright, so you can modify your copyright terms to best suit your needs. They’ve collaborated with intellectual property experts all around the world to ensure that their licenses work globally.
