Textbook Affordability - OER: Find OER

Finding Open Educational Resources for your Class

Finding the right Open Educational Resource (OER) is the most challenging part of using OERs in the classroom. The resources listed on this page can help you find an OER in your subject area. The bad news: you may not find an exact match. The good news: OERs are usually shared in such a way that you’ll be able to edit the OER to better meet your student needs. You can also mix, match, and customize multiple OERs like an open course pack.
