Congress defines OER as: “…a teaching, learning, or research resource that is offered freely to users in at least one form and that resides in the public domain or has been released under an open copyright license that allows for its free use, reuse, modification, and sharing with attribution.”


OER consist of educational materials such as open access textbooks, websites, documents, modules, and courses that can be legally and freely used. All OER are openly licensed, which means you can download and adapt these materials. Open licensing also allows you to create your own OER and then share these materials with others for them to reuse, revise, and redistribute.


Watch this helpful video from Iowa State University for more information about OER and why they are important.

What can I do with OER?

OER are openly licensed, most often with Creative Commons licensing or through the public domain. Creative Commons licenses allow you to engage with the 5Rs of open.

The 5Rs

  1. Retain: make, own, and control a copy of the resource
  2. Revise: edit, adapt, and modify your copy of the resource
  3. Remix: combine your original or revised copy of the resource with other existing material to create something new
  4. Reuse: use your original, revised, or remixed copy of the resource publicly
  5. Redistribute: share copies of your original, revised, or remixed copy of the resource with others

Creative Commons Licenses

Here is brief explanation of what Creative Commons Licenses are and how they work:

“The Creative Commons copyright licenses and tools forge a balance inside the traditional ‘all rights reserved’ setting that copyright law creates. Our tools give everyone from individual creators to large companies and institutions a simple, standardized way to grant copyright permissions to their creative work. The combination of our tools and our users is a vast and growing digital commons, a pool of content that can be copied, distributed, edited, remixed, and built upon, all within the boundaries of copyright law.”

Source: Creative Commons 

There are four components of Creative Commons licenses, which are:

  • Attribution (BY): Proper attribution must be given to the original creator of the work. This includes a link to the original work, information about the author, and information about the original work’s license.
  • Share-Alike (SA): Iterations of the original work must be made available under the same license terms.
  • Non-Commercial (NC): The work cannot be sold at a profit or used for commercial means such as for-profit advertising. Copies of the work can be purchased in print and given away or sold at cost.
  • No Derivatives (ND): The work cannot be altered or “remixed.” Only identical copies of the work can be redistributed without additional permission from the creator.

These four components can be combined to create a total of six different Creative Commons licenses, varying in openness and what they allow users to do.
