But the Internet Archive is much more than a website, it's a physical place right here in the Richmond District. If you walk down Clement Street until you hit Funston, you’ll see a building that looks like a Greek temple with white columns. On the roof you can see the number 1,000,000,000,000 (one trillion), the number of web pages they've archived. Every Friday at 1pm, they open their doors for a public tour.

Write-up of what it's like going on the Internet Archive tour, with photos! They also have a "Big Free Library" book exchange out front, too.
