San Diego Central Library in downtown San Diego's East Village occupies a nine-story, 366,673-square-foot structure at 330 Park Boulevard, designed by architect Rob Wellington Quigley and opened on September 30, 2013, after a $184.9 million construction. The building's steel-and-mesh lattice dome caps a three-story reading room that has become a civic landmark studied by architecture programs including NewSchool of Architecture & Design downtown. Collections span 2.6 million items across nine floors, including the Sullivan Family Baseball Research Center — the second-largest baseball memorabilia archive in the United States — and nearly 300 public art installations throughout the building. The library also houses e3 Civic High School on its sixth and seventh floors, making it the only public library in the country to contain a full charter high school within its footprint. Programming and capital campaigns receive supplemental funding through the Library Foundation SD, which underwrites author events, literacy initiatives, and technology upgrades beyond the city's operating budget. The building's most architecturally complex element is its ninth-floor cultural penthouse, which combines a 330-seat flexible auditorium, catering kitchen, outdoor sculpture court, and rooftop terraces offering panoramic views from Point Loma to the Coronado Bridge — all configured to host four concurrent public events.
