The first website contained a page that listed WWW servers. This was maintained until around 1992, when presumably it became impossible to keep up to date. One of the early websites listed on this page was for the Nikhef physics lab in the Netherlands. Willem van Leeuwen from Nikhef just got in touch to say that he's put a page back online at the original URL, and hosted some information about the early Nikhef website. Go have a look.
