As 16-millimeter prints become harder to obtain, public libraries across the country have been ditching celluloid in favor of DVD projection, despite its vastly inferior image quality. But Northbrook Public Library has doubled down instead, purchasing a 35-millimeter rig, expensive lenses for vintage widescreen formats, and a Dolby Digital sound system. As a result of these ongoing investments and the invaluable input of local projection specialist James Bond, the library has become the premiere venue in the Chicago area for classics from Hollywood’s golden age. Recent retrospectives have focused on Bette Davis, Billy Wilder, Cecil B. DeMille, MGM musicals, and film noir classics from 20th Century Fox. Coming in July: the films of Brian De Palma.
