OER refers to what is known as Open Educational Resources. These resources include textbooks and other learning materials that are openly licensed for use. These resources are accessible to Tarleton faculty for use in their courses, and can be distributed to students without them having to purchase a textbook. “It is similar to when a faculty selects a commercial textbook, one where [students] go to the bookstore and buy it, they can go [onto the OER database] and can select different OER’s that they want to use in the classroom,” Tarleton Libraries’ Scholarly Communication & OER Librarian Katie Pierce Farrier said. “And then, once they have selected that OER, as long as a student has the link and an internet connection, they can access that OER, and they will never lose access to that OER.”
