The Domesday project has faired rather better than many other projects it's content is accessible online:

http://www.bbc.co.uk/history/domesday

And I believe the content on the original Laserdiscs has been reverse engineered more than once. Hopefully once content is on the web (unless it's behind robots.txt) it gets sucked up by the Internet Archive.

That of course doesn't take care of any rendering issues.
