In Sarcophagus, in the scene where Avon is trying the buttons on the blue egg, Cally enters carrying a cumbersome object, saying: "I've finished with the book screen, Dayna. You said you wanted it."

It looks vaguely like a microfilm reader, rather uncomfortable to hold and not the sort of thing you can read in bed, but I assume it was meant as the bookform of the future.
