Open Textbooks and Open Educational Resources (OERs)

What Are OER?

OER are teaching, learning, and research resources released under an open license that permits free use, adaptation, and redistribution by others. 

They can include:
  • Course syllabi or curricula
  • Course materials (handouts, assignments, learning objects)
  • Lesson plans/modules
  • Open textbooks
  • Videos/media
  • Games
  • Tests, quizzes, or assessments
  • Tutorials
  • Software

OER allow users to:

  • Retain: users have the right to make, archive, and “own” copies of the content;
  • Reuse: content can be reused in its unaltered form;
  • Revise:  content can be adapted, adjusted, modified, or altered;
  • Remix: the original or revised content can be combined with other content to create something new;
  • Redistribute: copies of the content can be shared with others in their original, revised or remix

For more information about OER, check out the OER Toolkit (College Libraries Ontario).
For an overview of how to get started using OER, see The OER Starter Kit by Abbey Elder, 2019.

The 5 R's of Open Content

The Open Education movement is built around the 5 R's, a series of rights that instructors have over the open content they use in their classes:

Retain: ​The right to make, own, and control copies of the content.

Reuse​: The right to use the content in a wide range of ways (e.g., in a class, in a study group, on a website, in a video)

Revise: The right to adapt, adjust, modify, or alter the content itself (e.g., translate the content into another language) 

Remix​: The right to combine the original or revised content with other open content to create something new. 

Redistribute​: The right to share copies of the original content, your revisions, or your remixes with others.

Not all of the free resources you use in class are OER.

OER are openly-licensedfreely available educational resources that can be modified and redistributed by users. 

  • Openly-licensed: You can read about this in the Open Licenses and Your Rights tab. 
  • Freely Available: The resources must be freely available online with no fee to access. A true OER is free to access at all times, unless the resource is printed and must be bought for the price of materials (usually no more than $50).
  • Modifiable: The resource must be editable. This means that it must be licensed under an open license that allows for repurposing and remixing. 
Examples of Non-OER
Material Type Openly Licensed Freely Available Modifiable
Free Web-Based Resources Under Traditional Copyright No Yes No
Subscription-Based Library Collections No Yes* No
Open Access Articles & Monographs Yes Yes No**

*Library materials are free for students and faculty to access, but they are not free for the University. 

**Some OA articles & monographs are able to be remixed, but authors often hold back these rights since their main concern is the free distribution of their scholarship, not its adaptation. 

OER are openly licensed.

Open licenses like Creative Commons licenses are often used to communicate what a user can do with a resource, and what rights its author would like to retain. These licenses give others a variety of permissions, making their use or reuse of your resource a faster and more transparent process. For example, some creators may wish to share their work, but not to allow users to sell adaptations of their work. 

CC BY License icon

The most common CC license is the Creative Commons Attribution license (CC BY). This license allows users to adapt and reuse content with limited restrictions. The only requirement for reusing a CC BY-licensed work is that any new work created must provide attribution to the original creator and a link to the original work.
