Disregard your claustrophobia and the justifiable fear of getting smothered beneath the Pisa-like spires of books, and have one of the helpful Sonic Youth clerks help you to the section on "Hackysack, Yo-Yo's and Juggling." Nearby, look over the three full shelves devoted to the history and study of prostitution. And don't forget the Frank Cotton Memorial Oddball shelves, named for the late head clerk of Acres, who until his death in 1988 functioned as the store's only computer. There, you find a volume titled "14,000 Things to Be Happy About," and another called "The Dot and the Line: A Romance in Lower Mathematics."
