UMUC announces that they have replaced all undergraduate textbooks with OER and other no-cost (to students) digital resources for this Fall semester. By Fall 2016, graduate materials will also be cost-free to students. This move was to save students money but also to change teaching to avoid relying on materials locked away in static textbooks.

We can do this at the University of Hawaii–contact oer@hawaii.edu to discuss further.
