Taylor, Paine's bio is available in three volumes, in paperback,
with an intro by James Cox--from Chelsea House, London, 1980.  Ts
It's part of the "American Men and Women of Letters Series."

By the way, when I send to Twain-l@yorkvm1 I get a "can't send"
message back.  What am I doing wrong?  Had to send my message out
as a reply to another message to get through.

Thanks for the other general info.
Best,

David Barrow
