Open Educational Resources (OER) are learning and teaching materials that make education more affordable, accessible, and adaptable to both students and faculty. OER reside in the public domain or are licensed under an open license (such as Creative Commons) that allows users flexibility to revise, remix, reuse, redistribute, and retain content depending on the license.

Higher education and library initiatives encourage faculty to implement OER to increase affordability in education and support lifelong learning. Visit this site for more information on Northern Illinois University's OER initiatives.
