The early years: 1930–1950
The second development was the spinner rack, a metal pole with a four-sided wire frame designed to vertically hold rows of racks of paperback books. Retail store owners no longer had to devote feet of valuable counter space to low-profit paperbacks. Dozens of paperbacks could be displayed vertically in five or six square feet of floor space. (Similar racks were available for magazines and comic books.) By the late 1940s, paperback spinner racks were ubiquitous in large and small towns across the United States, in every local grocery store, drug store, dime store, and bus and train station, displaying everything from best sellers and mysteries and westerns to classics and Shakespeare. In 1955, in William Inge's Broadway playBus Stop, it did not seem unbelievable that a long-distance bus traveller stranded by a snowstorm in an out-of-the-way cafe walks to a shelf and picks up a paperback copy of Four Tragedies of Shakespeare. "Sometimes one can find Shakespeare on these shelves among the many lurid novels of juvenile delinquents," he comments.
