Suzanne, Thanks for the info on the U.W. Allen collection. We'll get in touch with them. You know, Suzanne, each time i have actually put out a request for information on this list you have responded with some useful and/or interesting reply. I really appreciate your help. The message list gets so full of' DISCUSSION sometimes that I start thinking of signing off( even though that is a legitimate, often enlightening and occasionally entertaining reason for a discussion list to begin with). Then responses like yours to a specific question remind me that this is why I joined in the first place. Thanks again, Mariana
