eTextbooks should be linked to your course within Blackboard. Look in the top-left corner under START HERE in your Blackboard course for the eTextbook link, then click the book cover to enter the book. Note: access to a course eTextbook will be available on the course start date, not before.
A course designated as an ILR course does not have a textbook. Instead, students are assigned a variety of readings by unit. Check the unit Study Guide to access links to that unit's required and suggested reading assignments.
