The Internet Archive created the Wayback Machine. This nifty little tool makes it possible to surf pages stored in the Internet Archive's web archive. It was unveiled on October 24th 2001 at Berkeley's Bancroft Library. You can visit the archive at www.archive.org
. Enter an URL and you are ready to go back in time. I have included some of the links from the archive:
