Licensing & Attributions

OER Licensing

OER are typically licensed under open licenses, such as Creative Commons licenses, which allow users to freely use, adapt, and share the materials. Creative Commons (CC) licenses provide a standardized way for creators to grant permissions for the use of their work. These licenses specify how others can use the content and what kind of attribution is required. They help creators communicate how their works can be used and ensure that their rights are respected while allowing others to legally share and build upon their creations.

Keeping Track of Licenses

Since many faculty using OER end up revising and remixing material using multiple sources, it's a good practice to start a running list of potential resources as you start a new OER project. For an example, here's a list of OER resources for Statistics Links to an external site. compiled by Mesa Math Professor Kelly Spoon. When you can remix resources, the resulting creation has the strictest license of all the material used.

Attributions v Citations

Attributions exist for works in the public domain or under a Creative Commons license. Citations exist for copyrighted materials and using whichever style guide is adopted by your discipline. We will explore Creative Commons and other types of licensing below along with attributions. 

Creative Commons Licenses

To get acquainted with the different Creative Commons licenses, you can click on the image to the right to watch a 5-minute video or look through the text and infographic below. The licenses are listed from least restrictive to most restrictive.

List of Creative Commons Licenses

CC0 (Public Domain Dedication)

  • This isn’t technically a license but a waiver. It allows creators to waive all their rights, placing their work in the public domain, meaning anyone can use it for any purpose without needing permission or providing attribution.
  • No restrictions or requirements for usage.

CC BY (Attribution)

  • This license allows others to distribute, remix, adapt, and build upon the original work, even commercially, as long as they credit the original creator.
  • Most flexible CC license in terms of what others can do with the work, as long as proper attribution is given.

CC BY-SA (Attribution-ShareAlike)

  • This license lets others remix, adapt, and build upon the work as long as they credit the original creator and license their new creations under the same terms.
  • Similar to CC BY, but requires derivative works to be licensed under the same CC BY-SA license, promoting the sharing of derivative works.

CC BY-ND (Attribution-NoDerivatives)

  • This license allows others to use the work as long as they do not alter it in any way and credit the original creator.
  • No derivative works are allowed; only verbatim copies of the work can be shared.

CC BY-NC (Attribution-NonCommercial)

  • This license allows others to remix, adapt, and build upon the work non-commercially. New works must acknowledge the creator, but they don’t have to be licensed under the same terms.
  • Limits the use of the work to non-commercial purposes only.

CC BY-NC-SA (Attribution-NonCommercial-ShareAlike)

  • This license lets others remix, adapt, and build upon the work non-commercially. They must credit the original creator and license their new creations under the same terms.
  • Similar to CC BY-NC, but derivative works must be licensed under the same terms.

CC BY-NC-ND (Attribution-NonCommercial-NoDerivatives)

  • This license allows others to download the work and share it with others as long as they credit the creator, but they can’t change the work in any way or use it commercially.
  • The most restrictive CC license; it only allows others to download and share the work without modification and for non-commercial purposes only.

Visual Depiction of Creative Commons Licenses

Here is a visual depiction of the Creative Commons licenses, showing the "Most Free" to "Least Free" license restrictions. Note the icons used for each license type; you will begin to recognize them as you explore OER materials.

Modifying and Adapting CC-Licensed Materials

You want to remix the content and customize it for your students. Can you do that? Maybe, depending on the license.

On the chart below look for the green column with the ability to "Modify and Adapt." When revising or remixing materials you will want the ability to modify and adapt. That is doable, unless you have a material with a ND (no derivatives) license. ND licenses also limit your ability to change the language of the material.

It can get confusing when mixing materials under various licenses. Contact your OER librarian if help is needed! 

Tip: TED Talks are under a CC BY NC ND 4.0 International license. This is the most restrictive license. You cannot cut segments or revise to combine TED Talks. If you only need a portion for your students provide the minute marker for students to start or stop watching.
