Repositories and Search Tools

Learning Objectives

By the end of this section, you will be able to:

  • Identify four search tools for finding open educational resources.
  • Identify at least two search tools for finding openly licensed media.

In the last chapter, we reviewed some strategies for finding OER. Below, a set of available repositories, search tools, and resources are listed to help you find the right OER for you.

Best Bets

When starting your search for OER, it’s best to begin in a place with a wide variety of options. The websites listed below each have a different focus, but they are good places to start if you aren’t sure what to look for.

  • The Open Textbook Library is a great resource for finding open textbooks. If you want a textbook and nothing more, this is the place to start.
  • BCCampus Open Textbooks collects resources created, reviewed, or adopted by instructors at British Columbia universities. Materials can be filtered by Accessibility as well as whether they have been adopted by BCCampus courses, include ancillary materials, or have been reviewed by faculty.
  • Curated lists of OER, like the Iowa State University Library Guide to OER, can be useful for exploring a selection of open content in your subject area.

SUNY’s Openly Available Sources Integrated Search (OASIS)

OASIS is a search tool that aims to make the discovery of open content easier by searching multiple sources for OER and other open content at once. OASIS currently searches for open content from 79 different sources and contains approximately 330,000 records.

George Mason OER Metafinder

The Mason OER Metafinder (MOM) links to a wide array of open content, including open access books and articles, documents in the public domain, and OER. Because of its large breadth of resources, we recommend that you start your MOM search with only a selection of the “OER-specific sites” checked, rather than all the materials it can include.


MERLOT is a project that was started in 1997 by the California State University system. The repository includes thousands of resources contributed by members, including original content and links to resources found through other platforms.

Institutional Collections

Institutional repositories (IRs) aren’t just for sharing copies of research articles and student theses. They can also be used to store and share OER. Although not every college shares OER through their institutional repository, the colleges below do share collections of OER specific to their institution:

Subject-specific Repositories

Some open educational resources are shared through subject-specific repositories. A few notable examples of this type, including open publishers that specialize in one discipline, are listed below:

OER by Course

Some colleges choose to share information about which OER their instructors assign in courses. These lists can give you a good idea of what other instructors in your discipline have adopted and (if they have provided a review), what they think of their adopted resource.

Open Content (not explicitly OER)

Not all open content is made to be used in the classroom, but that doesn’t mean you can’t integrate them into your course. Open access book chapters and openly-licensed media can be great additions to your course.
