Find a Typo? Have a Question?

We checked and rechecked every page of the book, but no matter how careful you are, mistakes have a way of creeping in. If you’ve found an error, or if you just have a question, please email us or post a comment here and we’ll respond as quickly as we can. We appreciate your feedback, and we’ll use it to continually make the book (and this site) better!
