“The STEAM collection was an excellent and cost-effective fit for us, as art and various engineering fields have comprised the bulk of our MIT Press titles purchased in recent years. Our contribution to D2O was less than we usually spend on MIT Press books in STEAM fields, and provides much broader access than our usual title-by-title purchases. Our participation in D2O is part of a broader OA strategy in our collections. It contributes to the development of scholar-led, sustainable OA monograph publishing models, while also providing immediate benefits in the form of backfile access.”—University Libraries, George Mason University
