LOL I hadn't thought of it in years, but the first thing that popped into my mind when I read that last post was how I'd read Tolstoy's
Anna Karenina back in high school in the smallest book (I think) in the school library. The book itself was - maybe - 4" x 5", and the text block smaller than that, and (iirc) around three inches thick. In other words, not much bigger than a PDA screen. It did not, however, glow by itself.
