Creative Commons is a nonprofit organization that allows creators of artistic or creative works to choose how their creations can be used by others. There are 6 main types of Creative Commons licenses that allow others varying levels of freedom to use and modify the work, as long as proper attribution is given. The licenses range from allowing only downloading and sharing with credit, to allowing commercial use and modifications as long as credit and same license terms are applied. Creative Commons licenses provide an alternative to traditional copyright for creators wishing to grant permission for certain uses of their works.
