Finding OER

Finding OERs can be as easy as doing some basic internet searching. Since OERs are by definition openly accessible, and since OERs want to be found and used, you have probably come across OERs without even realizing it.

But you should also know about some of the main OER repositories. These repositories index a vast number and type of sources.

Searches 50,000+ records of curated, high-quality OERs

Searches 90,000+ records with the option to search other OER collections and the web

Searches across notable OER collections including MERLOT, OASIS, and OER Commons

Searches 380,000+ records from 90+ reputable OER sites

Looking for more specific types of resources? Or specifically for your subject? See this guide created by Ashley for recommended databases and repositories for textbooks, courseware, multimedia, and primary sources. You can also find OERs based on subjects.

When searching through OER databases and repositories, double check the copyright of each material you choose for your course. Many sites have a mixture of Open and Affordable materials, so it's always important to check and not assume that the materials are licensed as Open.

Share with the Team!

As an OA Awardee, you likely have already considered and selected resources you plan to use for your course. If so, please tell us how you discovered these Open or Affordable resources. Can you find any of these resources in OER Commons, Merlot or another OER repository? See if there are any related materials you may not have seen.


If you have not selected or finalized materials for the award yet, we recommend you continue your search through some of these tools. Share with the group some highlights of your searching.
