I think if you go to Bizer's webpage


http://www.bizer.com

and click on the link marked "corrections", there's a pretty extensive revision history for their charts with dates and whatnot. So that might help.

FWIW, I still use my C-map chip I bought in 2005 and have noticed very few material changes, I still buy a new map every couple of years though.

Good luck!
