Proprietor Rich Sandler closed his used-book warehouse in Miami-Dade last year and moved north to a tiny building in Davie, bringing with him an idea the time for which is long overdue: reading material sold by the pound. There's precious little method to his madness. He divides titles only into fiction and nonfiction. Beyond that you simply wander around, find something that interests you, and toss it on a scale. Sandler charges $1 per pound for everything, two-pound minimum. We picked up the Encyclopedia of World Travel volumes one and two and a copy of Chapman's Piloting, Seamanship & Small Boat Handling, all for $7. Such a big, heavy deal.
