Don't worry Bruce,
You do right! All of us afflicted by anno domini will take some useful information to the underside of soil, obviously some more so than others, but trying to get as much as possible in an accessible form has got to be a good thing. There will be errors in the errors, of course, but those who know should be able to minimise this (in a similar way to what is done in Wikipedia?).
My twopenn'orth,
Mick.
