What stands out about this textbook is the highlighted key terms throughout.
The large type is a practical choice for anyone who reads in bed with a small lamp.
Getting a digital download means you get the book before anyone else.
What stands out is the one-size format, which is common for most college course materials.
A nice touch in the revised edition is the online access code included with purchase.
