As a student transitioning from a Library & Information Science graduate program to the real world, this book was amazingly helpful, both in its breadth of information and the way in which it is delivered. Taxonomy is complicated! Many people think they know what it means, and most are wrong. Beyond the navigational application of a taxonomy is its conceptual implications, which, when applied correctly, provides a structure and organizational framework that empowers the entity for which it was built. The approach, organization,and delivery of information that this book reflects, is a perfect example of the content it aims to communicate. What better way to illustrate this complex practice of creating a visual system of classification and order? Ms. Hedden is known as an expert in the field of taxonomy and classification, and this comes through in what I, a now employed taxonomist, refer to as my "bible".
