Searching the Internet Archive
"The Wayback Machine"
The Internet Archive (archive.org) has capitalized on the popular use of the term "Wayback Machine" and uses this term as the name for its snapshot archives of the World Wide Web.
This service allows users to see archived versions of web pages of the past—what the Archive calls a "three dimensional index". Web pages that no longer exist, bankrupt companies sites, old versions of popular sites... you can find it all on the Internet Archive.
The term "Wayback Machine" in the context of the Internet Archive has become so common that "Wayback Machine" and "Internet Archive" are almost synonymous.
Browse through 85 billion web pages archived from 1996 to a few months ago. To start surfing the Wayback, type in the web address of a site or page where you would like to start, and press enter. Then select from the archived dates available. The resulting pages point to other archived pages at as close a date as possible.

How to use the Wayback Machine to find people
Suppose you see that someone worked for a particular firm back in 2001. You can look up the URL for that firm and see what their website looked like during that year!
Maybe the company does not even exist today (Enron, Andersen Consulting, etc.) You can find their old website archived in the Wayback Machine.
Sometimes these links will include old contact information that can be used as leads to find current information.
