I remember getting involved in this when I was at school. It was part of the inspiration behind <a href="http:&#x2F;&#x2F;www.geograph.org.uk&#x2F;" rel="nofollow">http:&#x2F;&#x2F;www.geograph.org.uk&#x2F;</a>  where we set up a free archive of geographical-themed pictures of the UK.<p>Back in around 2005 I contacted the original project leader to see if we could somehow help with the preservation, but at that time it was thought sorting through the copyright issues would make it impossible. I was happy to see it was eventually released online!<p>Long term archival was a concern for Geograph - aside from adopting a cc-by-sa licence on image submissions, we also worked with the National Archives to ensure a digital copy of the image archive is preserved.<p>The Domesday project occupies what seems now - the briefest window of opportunity - to create something that would become obsolescent so quickly! But I think its true value lies in acting as a warning to others...
