BusinessWeek's Best Seller list is based on a survey of chain and independent booksellers that carry a broad selection of books on economics, management, sales and marketing, small business, investing, personal finance, and careers. Well over 1,000 retail outlets nationwide are represented. Current rankings are based on a weighted analysis of unit sales in July. Titles that have been on the List for more than two years appear as Long-Running Best Sellers.
