Open and Affordable Textbooks

Open Educational Resources Guide

Open Educational Resources

Open educational resources (OER) are any learning or teaching resources that are available at little or no cost. These can include textbooks, course readings, course syllabi, multimedia, games, assessment tools, or any other material that can be used for educational purposes.

The resources on this page have been compiled by Rutgers University librarians to help faculty members and instructors interested in incorporating OER in their classroom, or for those wanting to find these materials in order to apply for the Open and Affordable Textbooks (OAT) Program. For more suggestions, or if you would like to be referred to a subject specialist in your area of teaching, please contact an OAT team member.
