I purchased a used version of this textbook for a college course and am entirely pleased with it. The cover is a bit hammered, but that is what I expected of a used textbook. The pages are clean so as to allow me to read and underline passages when necessary. The layout of the textbook is not overwhelming or crowded. It is a pretty simple task to digest a page before turning to the next. Additionally, the authors do an excellent job on the Concept Review and Reinforcement as well as the Key Terms sections located at the end of every chapter. Nicely done.
