Internet Archive

Archives in Golden Gate Park & the Avenues

Follow trails of deleted White House tweets, lost Grateful Dead tapes and defunct Nintendo gamer magazines to this 1923 Greek Revival landmark. In a former Christian Science church, the nonprofit Internet Archive hosts 20 petabytes (that's 200 million gigabytes) of bygone media, and counting. The archive is run by 100-plus dedicated volunteer archivists, depicted in ceramic sculptures by artist Nuala Creed. Check website for Friday visits (1pm to 2pm) and tours, often led by founder, internet pioneer and Alexa inventor Brewster Kahle.
