For the fifth year running, the University of Kentucky Libraries has issued grants to faculty to develop open educational resources for their courses, as a replacement for the commercial textbooks they traditionally use. So far, according to the institution, the grants have saved nearly 9,000 students about $1.14 million in curriculum expenses, about $129 per student per course.
