Jim Collins marks 40 weeks on PW's hardcover list this week—and that isn't even the best news. His book, Good to Great: Why Some Companies Make the Leap... and Others Don't, has reached the one-million-copies-sold milestone; its first printing, reports HarperBusiness, was 75,000. The book has gone back to press some 47 times and the CD audio edition has been reprinted 18 times.
