I am a print designer familiar with Adobe products. Two years ago I took a Dreamweaver class, and because I did not practice often (the adage "use it or lose it" truly applies when learning a deep program), I forgot much of what I learned. Now I have to get that website I started two years up and running, and my class notes make little sense. This is why I'm so thankful to have this complete 9-books-in-one reference guide!!! What I really like about this book is the clarity of organization, and how easily I can skip around for specific information. I also found it helpful to read the first few sections for review and to fill in my gaps of knowledge. There are also more technical sidebars for the more technically oriented, but the body of the book is very accessible. At this time, I'm happy with this one book sitting next to my desk, and I don't feel the need to have additional books on the subject.
