Two days ago I went to the O'Reilly Tools of Change Publishing conference at the Marriott in Times Square. It's a pretty well-attended conference, focused on e-books, e-book readers and embracing digital change. Twelve hundred people showed up to hear about what's next. The book industry has not grown much in the last six years, but neither has the U.S. economy. However bookselling will change more in the next six years than in the previous 200.
