The San Francisco Public Library has announced the winners of its Library Card Design Contest organized by ImproveSF, a citywide program designed to help the local government to work directly with its citizens on different projects. Five winning designs—one from each of five age/grade categories—were ultimately selected from a field of 3,500 entries submitted in September and October. A panel of judges initially winnowed the field to 10 finalists in each age group; the public then selected the winners by voting at ImproveSF.com.
