I'm sure there is plenty of other information out there that is far better and more complete, for a price...
This was available on the 'net, and it was free...
The author freely admits that the information is incomplete, and will probably require massive editing, correction, etc., in the future..
It is still one of the few sites I found with maps for the historical period that bore some resemblance to the sea-level map that blam posted..
The additional info was a "plus" in my opinion..
