Creative Commons

Most OER are released under Creative Commons (CC) licenses, which explicitly allow for uses beyond those typically allowed under copyright law.


In essence, CC flips the traditional copyright model, in which all rights are reserved except those expressly granted. Instead, under CC all rights are granted except those expressly reserved.

CC materials do not reside in the public domain; the creator still retains legal ownership of the work. However, unlike traditionally copyrighted materials, all CC materials may legally be redistributed to anyone, at any time, indefinitely.

In addition, most CC materials can be revised and remixed before being redistributed. The exact permissions allowed for a particular work depend upon what CC license is applied to it.

Applying for CC

If you are applying a CC license to work you created, the Creative Commons license page can help you choose which license is right for you.

It will also give you language to use to apply the license.
