I was, however, in the library at the time. Surrounded by, you know, shelves of books. And tables set with lamps with green translucent lampshades. And leather-covered chairs with curvy wooden legs. And, in the room the guy just came from, if memory serves, a wall occupied with the obsolete but still quite physically present remnants of rows of drawers of the library catalog on small cards.
Things that would typically convince a person looking for a library that they have successfully reached their destination.
