Lem described future e-books and audiobooks in his 1960’s novel “Return from the Stars”.
An Astronaut returns to Earth after a long space expedition. One and a half centuries have passed on Earth because of the Einsteinian twin time paradox. During that time Earthly civilization changed in a fundamental way: people gave up risk for the sake of prosperity and safety. The novel presents a fascinating vision of “Earth as an alien planet,” full of new technological inventions. One them are books of the future:
I spent the afternoon in a bookstore. There were no books in it. None had been printed for nearly half a century. And how I have looked forward to them, after the micro films that made up the library of the Prometheus! No such luck. No longer was it possible to browse among shelves, to weigh volumes in hand, to feel their heft, the promise of ponderous reading. The bookstore resembled, instead, an electronic laboratory. The books were crystals with recorded contents. They could be read with the aid of an opton, which was similar to a book but had only one page between the covers. At a touch, successive pages of the text appeared on it. But optons were little used, the sales-robot told me. The public preferred lectons – like lectons read out loud, they could be set to any voice, tempo, and modulation. Only scientific publications having a very limited distribution were still printed, on a plastic imitation paper. Thus all my purchases fitted into one pocket, though there must have been almost three hundred titles. My handful of crystal corn – my books. I selected a number of works on history and sociology, a few on statistics and demography, and what the girl from Adapt had recommended on psychology. A couple of the larger mathematical textbooks – larger, of course, in the sense of their content, not of their physical science. The robot that served me was itself an encyclopedia, in that – as it told me – it was linked directly, through electronic catalogs, to templates of every book on earth. As a rule, a bookstore had only single “copies” of books, and when someone needed a particular book, the contents of the work was recorded in a crystal.
