The Wayback Machine
Browse through 85 billion web pages archived from 1996 to a few months ago. To start surfing the Wayback Machine, 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. If you have trouble connecting to the Wayback servers, the Internet archive at the New Library of Alexandria, Egypt, mirrors it.
The Internet Archive is a 501(c)(3) non-profit that was founded to build an Internet library, with the purpose of offering permanent access for researchers, historians, and scholars to historical collections that exist in digital format. Unfortunately, keyword searching is not currently supported by either the archive or the Wayback Machine.
Founded in 1996 and located in the Presidio of San Francisco, the Archive has been receiving data donations from Alexa Internet and others. In late 1999, the organization started to grow to include more well-rounded collections.
Now the Internet Archive includes texts, audio, moving images, and software as well as archived web pages in their collections.
