Open Educational Resources, also known as OER, are educational materials that are intentionally created and licensed to be free for users to own, share, and customize. These materials can range from a single lesson plan to an entire textbook. Not only can they save students money, but they can also be modified and remixed to better meet the learning objectives of courses. In this session, we will describe and define OER, talk about copyright and licensing issues, identify examples of OER in practice, and share our experience and knowledge of OER in use at Cornell University. Presented by Mike Priehs, Cornell University Library Copyright Services.  Attend in-person and receive a pair of Open Access socks!
