I imagine this book working well as a text for an introductory course on typography. Part of that impression comes from the clear need for an instructor to tie the material together and bring it to life with practical exercises.
The format addresses an audience that reasons in visual terms. Each two page spread, sometimes each page presents a complete thought. Illustration demonstrates each of the points made. The first section presents a history in sound-bites, highlighting the history of print and placing it in historical context. Next, about fifteen pages establish the anatomy of a character and typeface, and the words that describe it. Successive chapters describe basic visual hierarchy and composition, page formatting and legibility, technology as of 1993, and samples from typographic curricula at colleges around the US. The last and larger half of the book presents case studies in a few pages each, then nearly 100 pages of type specimens. Each specimen appears in enlarged form, making important details easily visible. Next, the specimen appears in several examples of body text, giving the font's real reading experience at several point sizes and spacings.
This book does a fair job with the basics, and educators may find ideas that will help their own classrooms. Experienced typographers, even students taking their second course, will bottom out quickly. Your experience of this book will depend on how you use it. A good instructor could find it a helpful adjunct, but self-taught students won't get the direction they look for.
