It happens sometimes. What are we calling physical books now? Book-books as opposed to e-books. I don’t feel a need to call them anything other than books, unless the distinction needs to be made. In this case, it does; I bought a paperbook.
Sometimes people buy them for me — people who know me well, who consider the content as well as the cover design and age. Pulp sci-fi collections are my favourite; recently I was given a 1963 Penguin science fiction compilation edited by Brian Aldiss, the classic orange-and-white cover overlaid with a scribble of something that might be a robot, or a satellite, or a bucket of spatulas. It includes stories by Isaac Asimov, Walter M. Miller, Clifford D. Simak, Aldiss himself, “up-and-coming British author Jim Ballard”…and John Steinbeck.
