The New York Times covers the new XKCD book:
So, are we seeing an all-too-rare example of the triumph of print books over digital content? Does even an online legend like the 24-year-old Mr. Munroe crave the respectability of print? (Mr. Munroe once before climbed the respectability ladder when in October he competed against the illustrator Farley Katz of The New Yorker in a “cartoon-off.” No winner was declared.)
In fact, the xkcd story previews the much more likely future of books in which they are prized as artifacts, not as mechanisms for delivering written material to readers. This is print book as vinyl record — admired for its look and feel, its cover art, and relative permanence — but not so much for convenience.
