of the wayback machine for Internet. Just think of the proportions of this project. To store all webpages of the whole internet as they change in time. It is of course impossible to catch everything.
It works remarkably well. For example www.boldsoft.com just link to some strange jumbo page... But in the wayback machine I can travel back in time to 4 October 2002. The pictures is mostly missing but I can read the text, documentation, ads etc. Very useful. I grabbed a chm-file with Bold references and added it to my archive of Bold documentation.
