The University of Southern Maine Libraries have joined The Open Textbook Network (OTN), a national consortium of colleges and universities working together to promote and develop open educational resources (OER). The primary focus of these efforts is on faculty adoption of free, open textbooks. OTN saves students money and provide day-one access for every student.
