Types of Licenses
Creators choose a set of conditions they wish to apply to their work.
All CC licenses require that others who use your work in any way must give you credit the way you request, but not in a way that suggests you endorse them or their use. If they want to use your work without giving you credit or for endorsement purposes, they must get your permission first.
You let others copy, distribute, display, perform, and modify your work, as long as they distribute any modified work on the same terms. If they want to distribute modified works under other terms, they must get your permission first.
You let others copy, distribute, display, perform, and (unless you have chosen NoDerivatives) modify and use your work for any purpose other than commercially unless they get your permission first.
You let others copy, distribute, display and perform only original copies of your work. If they want to modify your work, they must get your permission first.
The use of the conditions above can be combined to create one of six specific licenses regarding use:
- Attribution CC BY
- Attribution ShareAlike CC BY-SA
- Attribution-NoDerivs CC BY-ND
- Attribution-NonCommercial CC BY-NC
- Attribution-NonCommercial-ShareAlike CC BY-NC-SA

Public Domain Mark & Designation
The following applications are not considered to be licenses, as copyright is not claimed. Read about the differences below.
Applying a License
If you wish to apply a Creative Commons license to something you created, consider the following before selecting your license:
- the material needs to be eligible for copyright protection and you need to be the copyright holder
- once you apply a license, it is irrevocable – you can later remove or change the license, but if others have already copied or used the item under its earlier license, their use remains protected.
Creative Commons License Chooser Tool
The license chooser tool, offered by the Creative Commons, creates a machine-readable license based on your specifications.
Marking Your Material with the License
When you’ve carefully reviewed the license types and chosen the one you’re comfortable applying to your material, the next step is to mark your material with the information. It is highly recommended that you use the Creative Commons License Chooser to guide you through the process.

Using Creative Commons Materials
Before using an item that has a Creative Commons license, you’ll want to review the license guidelines to ensure that your anticipated use is acceptable. If you determine that your anticipated use is not permitted by the license guidelines, you’ll need to contact the license holder to obtain special permission. An alternative solution would be to search for suitable replacements that offer the license type you need.
If you use an item marked with a Creative Commons license, it’s important to give attribution according to the license conditions. As a rule of thumb, good attribution includes the original item’s title, author, source (where it can be found), and license. More information about attribution, including examples, can be found here.
