The Internet Archive was founded in 1996 to "build an internet library" and offers a searchable collection of digital collections. Internet Achive's Wayback Machine launched in 2001 has archived web pages going back to 1996, enabling historical snapshots of the web, has undergone a gamma-ray powered transmogrification. Well, they redesigned it and it's now in open beta.
The new version is two-fold; first, it's a wholesale migration of the site from a proprietary software to an open source platform, which should make the whole thing faster; second, there are interface changes that make it easier to be more precise in your digital time traveling.
The new version is visually updated and less cluttered. (Bonus: teal highlights on the search page!) Below the URL search box are a button for the latest version of the site you're seeking and another to see all results.
On the results page, the timeline toolbar gives you some instant and visualized information on where you are in the history of your site and how often and when the site was crawled. The calendar interface makes it easier to navigate to different versions.
