Query: Out of Date

This book is completely out-of-date because it doesn't mention the Internet, which has revolutionized bookselling.If you have have access to the Internet and want to be a book dealer, this is NOT the book for you. If you are computer-less and have no concept of the Internet, then you are fighting an "uphill" battle and will only loose money being a bookdealer in this day and age.
