Something very important and very weird is happening to the book right now: It’s shedding its papery corpus and transmigrating into a bodiless digital form, right before our eyes. We’re witnessing the bibliographical equivalent of the rapture. If anything we may be lowballing the weirdness of it all.

The last time a change of this magnitude occurred was circa 1450, when Johannes Gutenberg invented movable type. But if you go back further there’s a more helpful precedent for what’s going on. Starting in the first century A.D., Western readers discarded the scroll in favor of the codex — the bound book as we know it today.
