Creative Commons (CC): Types of CC License

Creative Commons (CC) Licenses

There are six types of Creative Commons licenses. They offer tools for creators to indicate which usage rights of  their works are granted to the public.  The classification is based on a combination of four conditions, namely: Attribution, ShareAlike, NoDerivs, and NonCommerical.  The icons and descriptions of the four conditions are shown below:



This is an adoption of the guide Six Licenses for Sharing Your Work by Creative Commons under CC0.

Types of CC License

CC0 undefined Yes No Yes Yes Yes
Public Domain Mark undefined Yes No Yes Yes Yes

Creative Commons also provides options for placing a work in the public domain. Creators can choose CC0 if they want to waive all usage rights, in other words “all right granted”. Henceforth others can use the creator's work under CC0 for any purpose and without any restriction under the copyright law.  If a work is already in the public domain, the Public Domain Mark can be assigned to the work to make it easily discoverable and available to the public.
