" When a printed book—whether a recently published scholarly history or a two-hundred-year-old Victorian novel—is transferred to an electronic device connected to the Internet, it turns into something very like a Web site. Its words become wrapped in all the distractions of the networked computer. Its links and other digital enhancements propel the reader hither and yon. It loses what the late John Updike called its “edges” and dissolves into the vast, rolling waters of the Net. The linearity of the printed book is shattered, along with the calm attentiveness it encourages in the reader. "
