What is Creative Commons?
Creative Commons is a nonprofit organization that enables the sharing and use of creativity and knowledge through free legal tools.Their free, easy-to-use copyright licenses provide a simple, standardized way to give the public permission to share and use your creative work — on conditions of your choice. CC licenses let you easily change your copyright terms from the default of “all rights reserved” to “some rights reserved.”
Creative Commons licenses are not an alternative to copyright. They work alongside copyright and enable you to modify your copyright terms to best suit your needs.
What can Creative Commons do for me?
If you want to give people the right to share, use, and even build upon a work you’ve created, you should consider publishing it under a Creative Commons license. CC gives you flexibility (for example, you can choose to allow only non-commercial uses) and protects the people who use your work, so they don’t have to worry about copyright infringement, as long as they abide by the conditions you have specified.
