Before choosing a license for your work, there are two things to consider:

• A CC license or CC0 can never be revoked. The license you choose will stay with your resource until the copyright expires.
• Make sure that you own the copyright of the work you want to license. If you are creating a resource at your job, it might be your employer who owns the copyright. 

Which license should I choose?

Take some time to think about why and how you want to share your resource:

• Do you think people will use your media to create new things? Would it be ok if someone translated your text into another language? If so, consider using a license that permits your work to be adapted.
• Perhaps you don't want to keep any copyright at all and dedicate your work to the public domain. Then the CC0 is something to consider.

Use the CC license chooser

The CC license chooser guides you with questions through the process of choosing an appropriate license. It will also generate an appropriate HTML code, license statement and icons.

Where do I put the license statement?

It depends on the medium of your work, but somewhere where it is visible. The CC licenses are developed with the user in mind, so the most important thing is that it is easy for the users to find out how they can use the work. On a website or in a libguide, the license information could be in the footer, for instance. Make sure to include the link to the deed. Have a look at the attribution to the image below to see an example of a license statement.
