The short: if you design or build web forms, you must buy this book. Now.
The long: An awesome book about web form design best practices that is backed up by real data and studies. The book oozes design from its glossy stock and full color images to the layout and typography. Overall you can tell that Luke is a great designer and has considerable experience with the usability of web forms. Luke covers just about every topic of web form design from from basic layout to help text to error conditions and about a dozen other topics.
Overall Web Form Design is one of my favorite design and usability books on my bookshelf for its breadth, beauty and usefulness.
