If you're on this site, you don't need an introduction to "Accessibility" or the ideas behind Universal Design. The disability-sensitive mandate of accessibility simply does not get the kind of exposure it deserves, not counting contentious litigations. My particular interest before reading this book was limited to Section 508 compliance of websites that already validate as XHTML 1.1 but should be more 'accessible' (I do miss "Bobby"). To date, I have only found reference on mailing lists, which is laborious, or in somewhat esoteric compilations of essays by industry experts. Call me simple but that is not really very useful for someone who needs a clear, concise walkthrough. Mr. Keates' book does just that, and more. It lays out a methodology to redesign the *entire* process of thinking about products to imbibe a thoughtful attention to accessibility in every stage of development. As such, it is not merely a strategic pontification but a fantastic read that will encourage and inform you on actually carrying out your plans to develop a universally usable product or service. Excellent, eye-opening book!
