San Francisco Study Center publishes the Central City Extra, the monthly newspaper for San Francisco’s inner-city neighborhoods — the Tenderloin, Sixth Street and Civic Center. Innovative tabloid format and design, two-color with bleeds throughout, printed on book stock. Circulation: 8,000. Neighborhood freelancers help Study Center writers and artists produce this magazine that masquerades as a newspaper. It is cutting-edge journalism produced by a nonprofit publisher as a community service.
