I got a review copy of this at ALA. I was really excited about it too. However, the book didn't live up to my expectations. It was particularly choppy, each chapter (one chapter per tool, basically) was a self-contained unit, and it didn't flow. I think I would have liked a chronological tale rather than a biography of each tool.I found that it was repetitive. There was one chapter early on where the author told me the same thing 3 or 4 times, in nearly the exact same wording. On the plus side, there were any number of fun facts.
