The Mechanic Muse — From Scroll to Screen
The codex also came with a fringe benefit: It created a very different reading experience. With a codex, for the first time, you could jump to any point in a text instantly, nonlinearly. You could flip back and forth between two pages and even study them both at once. You could cross-check passages and compare them and bookmark them. You could skim if you were bored, and jump back to reread your favorite parts. It was the paper equivalent of random-access memory, and it must have been almost supernaturally empowering. With a scroll you could only trudge through texts the long way, linearly.Over the next few centuries the codex rendered the scroll all but obsolete.
