O’Reilly Network: How the Wayback Machine Works
„The Internet Archive made headlines back in November with the release of the Wayback Machine, a Web interface to the Archive’s five-year, 100-terabyte collection of Web pages. The archive is the result of the efforts of its director, Brewster Kahle, to capture the ephemeral pages of the Web and store them in a publicly accessible library. In addition to the other millions of web pages you can find in the Wayback Machine, it has direct pointers to some of the pioneer sites from the early days of the Web, including the NCSA What’s New page, The Trojan Room Coffee Pot, and Feed magazine.“
