SIPX is a cloud-based service that helps manage and share digital course materials. It saves students money by recognizing subscribed content and handles copyright permissions. SIPX provides instructors and students with easy access to course readings and analytics. Libraries can use SIPX to increase access to subscribed content and provide guidance to faculty on copyright and resources for online courses. Data on SIPX-supported MOOCs found most common readings were from journals and books from various publishers. Engagement was highest for instructor-generated materials and universally accessible content.
