And much more too.
Indeed! If you search for "metadyne" on the forum, it finds that I cited a paper on the history of driving licences. I found that (as I guess Graham did) via a Google search, and at the time I didn't realise how much else was there - just that it looked like good reliable research.
If you do reach the site's web pages, you will see from the heading that the author of all this - Mike Horne - died last year, which it is very sad to hear. Of course that raises the question (as for many such personal sites) of how all this stuff can be kept available, whether or not the work is ever continued. The link with the London Reconnections site does look hopeful it that regard.
