Creative Commons (CC) is a non-profit organization devoted to expanding the range of creative works available for others to use, build upon and share.
The CC website provides a set of copyright licenses and tools that help users create a balance from the traditional copyright law of "all rights reserved." Creative Commons licenses do not replace copyright, but they are based upon it.
Choosing a Creative Commons license for your own original works will allow others share, use, and remix your work.
The CC website has an explanation of the six licenses and they are listed below. There are four rights that Creative Commons licenses allow you to do.
Types of Licenses
Attribution CC BY
This license lets others distribute, remix, tweak, and build upon your work, even commercially, as long as they credit you for the original creation. This is the most accommodating of licenses offered. Recommended for maximum dissemination and use of licensed materials.
Attribution-noDerivs CC BY-ND
This license allows for redistribution, commercial and non-commercial, as long as it is passed along unchanged and in whole, with credit to you.
Attribution-NonCommercial-ShareAlike CC BY-NC-SA
This license lets others remix, tweak, and build upon your work non-commercially, as long as they credit you and license their new creations under the identical terms.
Attribution-Share Alike CC BY-SA
This license lets others remix, tweak, and build upon your work even for commercial purposes, as long as they credit you and license their new creations under the identical terms. This is the license used by Wikipedia, and is recommended for materials that would benefit from incorporating content from Wikipedia and similarly licensed projects.
Attribution- NonCommercial CC BY-NC
This license lets others remix, tweak, and build upon your work non-commercially, and although their new works must also acknowledge you and be non-commercial, they don’t have to license their derivative works on the same terms.
Attribution-NonCommercial-NoDerivs CC BY-NC-ND
This license is the most restrictive of our six main licenses, only allowing others to download your works and share them with others as long as they credit you, but they can’t change them in any way or use them commercially.
