From Scroll to Screen
So far the great e-book debate has barely touched on the most important feature that the codex introduced: the nonlinear reading that so impressed St. Augustine. If the fable of the scroll and codex has a moral, this is it. We usually associate digital technology with nonlinearity, the forking paths that Web surfers beat through the Internet’s underbrush as they click from link to link. But e-books and nonlinearity don’t turn out to be very compatible. Trying to jump from place to place in a long document like a novel is painfully awkward on an e-reader, like trying to play the piano with numb fingers.
— Lev Grossman, From Scroll to Screen
