Libraries can and should support open education. It fits with librarians' professional support for access to information as a public good, the institutional mandate of academic libraries to support teaching and research, and the professional obligations of librarians in public libraries to support continuing education. But before libraries do so, it is useful to understand the open education movement as a whole, including some of the key challenges facing both OERs and MOOCs and how libraries are well positioned to help address these challenges. By taking a holistic approach, libraries can aid the movement to facilitate universal, affordable, quality education for the peoples of the world and ensure that institutions, faculty, funding agencies, and governments avoid pathways to open education that might prove detrimental to scholarship as well as to society as a whole.
