How long will my students have access to eTextbook content in the Flash Books model?

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 after the course(s) has ended.  Students can also access their eTextbooks offline by downloading the Yuzu® app for iOS or Android™.
