Locate Deleted Web Pages (and get them admitted into evidence) with the Wayback Machine | Oklahoma Bar Association
The Internet Archive (https://archive.org/) is a massive storehouse of information. It bills itself as “a non-profit library of millions of free books, movies, software, music, websites and more.” If you haven’t spent some time on the site, you may be surprised at what is available there.
Many lawyers are familiar with the Internet Archive’s Wayback Machine, the site that preserves the history of web pages (448 billion Web pages!). So, if someone has deleted something from a web page that impacts a client matter, your first research stop is the Wayback Machine to view the history of the web page and see a copy of the older version of the site is available. The Machine scans pages on an irregular basis, so luck is involved. But if the information was posted for a lengthy time, your odds are good.
