Laura, I'm just back and a little swamped as usual. But I did want to say immediately that I think this is a great idea, and more likely to be productive of real information than any (partial) list I could give you. Virtually anyone interested in Mark Twain who is also connected with at least college level academia is likely to be on this list. Hope you get a bunch of replies. Talk to you soon....just as soon as I dig out of this e-mail mountain. Bob
