How to DJ Right

I just recently started taking DJ classes, and this book has been tremendous help. Historically, the barriers to entry have been a bit high in the DJ field, often leaving beginners like myself wondering where to start: what equipment do I need? what are the fundamentals I have to work on? The book fills this gap, providing a comprehensive guide on equipment, techniques, online resources and the general nature of the industry in a very clear format. I've browsed through other books on this subject (a rather limited selection) and none of them come close in terms of breadth and quality.
