Open Educational Resources (OER) can be any type of educational material— a class handout, an image, even a textbook, or an online course. OERs use open copyright licenses such as Creative Commons that allow for different degrees of openness and allow users, like faculty and students, to engage in one or more of the 5Rs:

There are a multitude of OER out there to choose from, including textbooks, courses, multimedia, data, and supplementary materials. These can be found by searching regular search engines (like Google) and using certain keywords, but it is much easier to find them through dedicated OER repositories or websites. Down below, you will find links to different repositories and databases that house Open Ed materials.
