OER is available from many sources. Finding quality, appropriate content for your classroom may seem like an overwhelming task. Fortunately, OER are frequently consolidated within online multidisciplinary repositories created by institutions and organizations. These repositories house, and/or make searchable, large volumes of course materials and textbooks. If you are interested in finding OER to in your classroom, a repository is a great place to get started.
Note: If you plan on revising any open content, please confirm that it is actually licensed for OER. Many repositories combine Open Access (not able to be revised) and revisable OER content. Make it a practice to confirm licensing for all OER you utilize.
