Open Education Resources: Finding OER

This guide provides basic information on finding, remixing, and creating Open Educational Resources

Faculty Select - Temporary Access

Find Open Textbooks

These OER textbook repositories are good places to start your search for OER.

Find Other OER

These collections contain some textbooks, but also ancillary materials such as test banks, lecture notes, web content, videos, presentations, and more. 

Tips for Finding OER


OER is often housed in online collections or repositories. Because even strong collections are not always well-crawled by Google, you may have to dig a bit. You can start with a metasearch tool. Tools like the Mason OER Metafinder (below) and OASIS Metasearch will allow you to search across platforms, which can save a lot of time.

Other Tips

  • Search directly in relevant repositories, like the ones listed on the left. OpenStax is great for intro or survey class texts, where Merlot and OER Commons are better for finding supplementary materials. Open Textbook Library and BCcampus include a lot of both! 
  • Some repositories are discipline-specific or have better disciplinary coverage than others. Seek out repositories that seem to cover your discipline well. 
  • Use the subject headings and filters in the repositories to weed out what you don't want. 

Suggested resource

"Faculty Guide to Open Educational Resources (OER)" created by the librarians at Tacoma Community College is a great resource that includes extensive lists of subject and discipline specific OER, images, video and audio. They have also collected all the resources together on one page for simple finding.

What if I Find Nothing?

Not all disciplines and subject areas are equally represented in OER repositories. If you can’t find what you need, consider:

  • Asking the subject specialist librarian in your area to help
  • Using library resources, such as articles and e-books, instead of textbooks
  • Modifying an existing OER or creating your own! UI’s OpenHawks OER grants can provide funding and support for such a project. 

Evaluating a Textbook

When deciding whether to adopt an OER, you’ll need to spend the same time evaluating it as you would a regular textbook. These guides can help:
