Library studying turned into a city-wide search for this specific 2002 edition of a philosophy text. Every shop said it was impossible to find, but I finally tracked it down in a tiny second-floor bookstore that smelled like old paper and tea. The owner was napping behind the counter with a cat on his lap. Sometimes the things everyone says are gone are just waiting in quiet corners for someone persistent enough to look. Also discovered three excellent dumpsters on the route—one had perfect geometric ventilation patterns. Productive Saturday.
