Hi harleygurl38,
You got it right, the "View Shipment History" section of your Student Portal will indicate any books being prepped for delivery or have already been delivered.
If you recently completed a course, it may take up to 24-48 hours for a new section to open up, as well as any textbooks to be prepared for shipping with the new course material.
In most cases, however, you'll only need your Digital Study Guide for any given course.
If you have any questions related to your program, take a look through or post a question in the Early Childhood Education Associate Degree virtual classroom. An instructor or one of your classmates will help you out.
Good luck with your studies!
