Sure enough, this books walks you, gentle reader, through some basic concepts of typography. But it contains too many explanations of terms and too little analysis of what these terms mean. It is also short on practical advice. For a good introduction to typography, take a look at Bringhurst: The Elements of Typographic Style, which will teach you much more. Bringhurst's book also has the advantage of being small enough so that you can carry it around at school or at work.
