Every project at KBDA is extremely collaborative, and this book is a great example. It would not have come to pass without some incredibly talented people. This includes Jill Vacarra, who helped with the structure and writing of the first edition; Keith Knueven and Allison Bloss, who created and continually refined the original design; and Wendy Lemmerman who did an extraordinary job helping to manage the editorial and design decisions for this second edition.

With unending thanks to Michael, who patiently waited for it all to be finished.
