Being still in the process of exploring this work, an evaluation now is necessarily, somewhat conjecture. The book, compared to others on the topic is more research fact oriented. It presents a different view of accessibility than other books in that others are more in the vein of 'how-tos'. This book is more concerned with definitions and contemporary evaluations. One should not assume to automatically reject the book, having heard this. The information exposed thus far, has not been found in other books on the topic. As such, this volume supports other studies of Web Accessibility and Computer Accessibility in general with material that illuminates the social environment, materials, devices and other aspects of accessibility. Again, there is material presented in this work that is not exposed elsewhere. It's a good compliment to other prose on the topic.
