What is Creative Commons?
Creative Commons is a non-profit organization that works to increase the amount of creativity and work that is available to the public for free. It is a set of licenses which gives permission to do various things, such as reuse and distribute content.
Creative Commons Licenses
Creative Commons offer six different licenses, each allowing different uses of your work. Publishing under a Creative Commons license is easy. All you have to do is select the conditions that you want to apply to your work by selecting how others may use it.
1. Attribution is the most permissive Creative Commons License allowing others to copy, distribute, remix, display and perform your copyrighted work and derivative works based upon it; but only if you are given credit for the original.
2. Attribution Share Alike is similar to the Attribution license. You allow others to distribute derivative works only under a license identical to the license that governs your work.
3. Attribution No Derivatives permits others to redistribute, display and perform only verbatim copies of your work, including commercially, not derivative works based upon it.
4. Attribution Non-Commercial allows others to use, distribute, remix, perform your work and derivative works based upon it but only for noncommercial purposes with the stipulation that you are given credit in the way that you requested it.
5. Attribution Noncommercial Share Alike permits others to use, distribute, remix and build upon your work non-commercially as long as you are given credit in the way you requested it.
6. Attribution Non-Commercial No Derivatives is similar to traditional copyright and is the most restrictive Creative Commons License. It allows others only to redistribute your work non-commercially as long as it remains unchanged and you are given credit in the way you request.
