Do you remember the internet of the ’90s? The blinking GIF animations, guestbooks, hit counters and websites that looked like digital yard sale flyers? What was cutting-edge back then feels like a relic from another era today.

But the old web hasn’t vanished – it’s been archived. Projects like the Wayback Machine from the Internet Archive, the Digital Public Library of America and countless other digitization initiatives preserve what would otherwise be lost forever. They make digital time travel possible – and it’s equal parts fascinating, educational and entertaining.
