Open Educational Resources (OER) are online textbooks, online courses, media, or other teaching and learning materials published under open access licenses. Many OER licenses allow users to “remix” their content to fit specific course goals. Most university-level OER are peer-reviewed, and are free or mostly free.
The low cost of OER allow faculty to broaden their course materials or mix-and-match textbook sections or chapters without requiring students to purchase or rent each book.
