As of this morning, I’ve got 347 books backed up on my Kindle. I have no idea what is the full storage capacity of the unassuming piece of plastic. I’ve heard it is in the neighborhood of 10 K books. That is genuinely cool unless and until the gizmo’s memory is wiped out by an EMP blast courtesy of a nuclear explosion or nasty solar flare.
It appears however that our need to cram multiple books into one neat little package is not a modern one. No. The idea is downright MEDIEVAL!
