A good book for learning about taxonomy. Good on the underpinnings, the process, how this taxonomist’s job works. Not so good on real world examples, though. This would have benefited from some case studies to help the reader see how the aspects of taxonomy creation and editing work. Because of this lack of examples, this felt a little unfriendly, like someone just reading the facts. Like the book was aimed at someone who has worked on a taxonomy project and wanted to know more about what they had just a "taste" of. From what I could tell, the facts on taxonomy are provided in more detail in this one place than you are likely to find elsewhere, making this an excellent reference. I was surprised that it didn’t feel all that dated – I suspect the software described hasn’t changed all that much in the past few years, and that wasn’t a major focus of the text anyway. I’d be interested in the author’s take on automatic discovery and indexing of facets for faceted search – she downplays this software capability that has been in use since before the book was written, and she doesn't explain why.
