摘要：People have been reading books for over 500 years, in more or less the same format. Book technology has changed in some measure during that time. Fonts have become more readable. Books have become more affordable. Still, the general form of the book has remained much the same. But the arrival of e-readers, such as the Kindle and the Sony eBook, offers the possibility of a major change. First, people may shift to reading existing books on those e-readers. Second, the shift may lead them to change the way they use books, for instance by letting people have many reference works at their fingertips. Third, the shift may change the content of books. And, fourth, the shift may change who publishes books, and sometimes which books are published.
