How will I receive my digital textbook?

Digital textbooks are provided through an app called Unizin Engage that is integrated directly into participating Carmen courses and appears in the left-hand navigation.

When will I be able to access the content?

You will have access to the content as soon as your instructor makes your Carmen course available to you. CarmenBooks content is preloaded before the semester.

How will I access the online homework system for my CarmenBooks course?

Access to publisher homework systems (Connect, MyLab, MindTap, etc.) provided through CarmenBooks works very similarly to access in traditional courses. The only difference is that you will not hit a paywall or be prompted for additional payment. You will have access to the course materials immediately.

How long will I have access to the material?

This answer is different depending on the type of material your course is using.
You will have access to digital textbooks delivered through the Engage reader for the duration of your enrollment at Ohio State. They remain on your Engage bookshelf, organized by semester.
Materials delivered via Publisher homework systems will have the same access periods they traditionally offer. For some of these that means a single semester; for others it can be a year or more.

I have already paid my tuition statement which included this fee, but I would now like to opt out. Will I receive a refund?

If you opt out before the semester’s opt-out deadline, but after having already paid for material, you will receive a full refund. As with standard opt-outs, there are no refunds after the deadline.
