"Fair Use and OER: Copyright librarians from across the country came together to create a Fair Use Guide that acknowledges and supports our ability to provide our course materials on Canvas. We also have open educational resources (OER) beyond Google if needed. The Merlot collection, Open Textbook Library and OpenStax College are just some helpful sites for those of us looking for materials to replace chapters in textbooks, texts in the humanities, and face-to-face lab instruction.
Further, the libraries suggest you talk with the Center for for Advancement of Digital Scholarship about processes in place that help you document Fair Use. They have tools on further information on their guide.
Kansas State University requires compliance with copyright law and, when appropriate, supports the exercise in good faith of full fair use rights by faculty, staff, and students – PPM 3020.30.
