"book-dealer, seller of books and paper," early 14c. (late 13c. as a surname), stacioner, from Medieval Latin stationarius "tradesman who sells from a 'station' or shop," from an adjective stationarius "not moving" (see stationary), or else an agent noun from station (n.). In the Middle English period, roving peddlers sold goods and wares; the sellers with fixed locations often were bookshops licensed by the universities; hence the word acquired a more specific sense.
