Just when you thought all your old design mistakes, copyright breaches and factual errors had been neatly discarded, along comes The Internet Archive (http://www.archive.org/web/web.php) which has been archiving websites since 1996. It isn't complete but it has this site going back to '98. It might be useful for finding pages for sites that are now defunct... or for finding the evidence for that libel or plagiarism claim!
