For an eTextbook, the DRM (Digital Rights Management) provided by the publisher will spell out the options available for the eTextbook. The length of time may vary from 120 days to complete ownership through a download. For eTextbooks that allow ownership beyond the course, students may access their eTextbook content by logging into their bookshelf at mydigitalcontent.com after the course(s) has ended. For offline access to the eTextbook, students can also download the Yuzu® iOS or Android™ apps from their respective app stores onto a maximum of two devices.
