eBook vs. Access Code
eBook
An eBook is a digital copy of a textbook or custom course material. eBooks purchased through CEI can only be read through Bibli-U: a free software platform that can be used on your desktop or mobile device.
Access Code
An access code is like a subscription to a course-specific website that includes what you need for your class. Access codes usually expire after a specific period and may or may not include an eBook. Before making your purchase, carefully read the product description.
