Secrets of the S.F. Public Library archive

When the San Francisco Public Library moved to its new location at 100 Larkin St. on April 18, 1996, it had a brand new archivist, Susan Goldstein, who brought the library into the 21st Century with new ideas, digitization and a proactive approach toward gathering more diverse and complete collections that represent the city. Goldstein, who retires this month after 28 years with the library, gave Total SF co-host Peter Hartlaub a tour of the archive and San Francisco History Center, then sat down to talk about her career, her favorite discoveries and what history has to say about San Francisco's current struggles. Produced by Peter Hartlaub. Music from the Sunset Shipwrecks off their album "Community," Castro Theatre organist David Hegarty and cable car bell-ringing by 8-time champion Byron Cobb. Follow Total SF adventures at www.sfchronicle.com/totalsf  Learn more about your ad choices.
