You may already know about the Internet Archive because of the Wayback Machine. Well, Sherman, the Wayback Machine contains an online history of the World Wide Web. Using it, you can find stuff that’s disappeared from current websites (and websites themselves that have disappeared).
That’s only a small part of the archive. If you’re a Deadhead or fan of other bands, check out the Live Music Archive. At your fingertips are thousands of concerts and other performances, with quality ranging from audience tape recorders to direct soundboard recordings.
