An $36,000 open educational resources initiative at HACC, a community college in central Pennsylvania, is expected to benefit 2,300 students in the first semester. That's about 13 percent of the total student population. The collective savings will be about $196,000 in textbook costs, more than five times the initial investment. Those savings will be doubled for instructors who use OER for a second semester.
