　　Acknowledgments
　　We both were privileged to work at the World Wide Web Consortium in the Web Accessibility Initiative (WAI). We've worked with hundreds of people around the world--all of whom are working to make the Web accessible to everyone. There are very few new ideas in this book; others have already documented most of these techniques. Our hope is to bring them together in one easy-to-use place. As such, this book references the work of many people and to them we give our thanks, in particular: Tim Bemers-Lee, inventor of the Web, director of the W3C, and an all-around amazing dude; Judy Brewer, the director of the WAI; the chairs and participants of the various WAI Working Groups; and the staff and members of the W3C.
　　We owe a debt of gratitude to the late Dr. John Slatin, both for his qualities as a community leader and as a friend. The John Slatin Fund Accessibility Project was set up to help cover John's remaining medical bills by connecting organizations with accessibility experts (http://www.knowbility.org/business/john-slatin/). We encourage you to contribute in any way that you can.
　　A round of applause for our technical reviewers: Brian Fling, Andrew Kirkpatrick, Gez Lemon, Anitra Pavka, and Terrill Thompson. Thanks to Shawn Henry and Ryan Turner for their feedback on the introductory and process chapters and to Aaron Leventhal for schooling us in WAI-ARIA. This book would not be possible without our editor, Simon St. Laurent.
