Once again you discuss the future of electronic books, like Amazon’s ever-more popular Kindle, without mentioning either hypertext or Ted Nelson, the concept’s progenitor (“Well Read,” February 14, 2009). Hailing from the revolutionary Sixties, when the World Wide Web emerged out of shady military research, hypertext interconnects everything ever written by means of hyperlinks, which can be thought of as footnotes, citations, and bibliographic references of yore. By and by, digitalization of books by Amazon and Google will create a seamless whole, the book of books. The repository of all recorded thought, that is. From book to book to book, the reader will be able to span space and time with consummate ease. From Umberto Eco to Immanuel Kant to Lady Murasaki, the reader will travel along the highways of human ingenuity without let or hindrance. The future of electronic books is an exciting subject primarily for this reason. And you miss it time and again.
