I love these books. The EVERYTHING books and COMPLETE IDIOT'S GUIDE's break down the information in easy to understand language. They pretty much cover a broad range of information instead of concentrating on one part. Great for beginner's. If you want indepth information on certain things, you might want to buy a book covering that subject. This book is pretty much unused. I bought it to help me with my online business (which I never really started). I skimmed certain parts.
