An Open Educational Resource is any open-licensed material that can be used for educational purposes. If the licensing is open, then the materials are usually free or of very low cost. Additionally, OERs are often open-source, and through their licensing, permit others to modify the content. Large examples of OERs for math include free textbooks and e-books, GeoGebra, and WeBWorK. A smaller example might be a worksheet designed by an instructor that has been openly licensed, or a web site with a free educational applet.

General OER information

OER Math Textbooks

OpenStax ( is a nonprofit organization associated with Rice University. They have several vetted OER math textbooks in their collection (which is growing).

A list of open textbooks in math: A cursory examination reveals some of the items listed here are incomplete. However the list is extensive, and includes many items worth looking into. If you are serving on a textbook selection committee, please visit this list and investigate relevant books. Keep in mind that while publishers have book reps to bring options to your attention, there are no salespeople for these options.

Another source of OER courses is the Open Learning Initiative at Carnegie Mellon. There looks to be a small number of math courses here.

These are items from the links above that have raised eyebrows and passed a cursory examination.

If an item from the list at is not listed here, it probably just hasn't been assessed yet. If you find more candidates among that list, please add them here.
