I work a lot with various businesses and part of my work includes web design. In the past, I was also a Director of Education for PeopleSoft and I have served in similar capacities for a variety of companies in Silicon Valley. As such, I am well-qualified to judge the merit of this materail and I must say it is a real bargain for the 800+ one stop shopping reference for DreamWeaver 8.
The book is well-organized and it could be used as either a text or an "as needed" reference manual. The descriptions are clear, to the point and easy to find. It also deals with topics such as inserting Flash video and has a lot of meaty content in addition to simple instructions.
This book is truly a "must have" reference for any web developer!
