This is a great read for someone who has never considered type before. Those graphic design graduates who were never taught type in ground-up way, self-tought pros wanting to learn some theory or for editors, subs or marketing people who are now doubling-up as designers. It really makes you share the authors' total enthusiasm for type, although there are other equally clear introductions that are either cheaper or offer more. If you want hard knowledge rather than enjoyable prose check out The Mac is Not a Typewriter, Rauari McClean's pre-DTP Manual of Typography, or About Face by Rotovision.
