I'm just starting some work on Twain and Barnum.  Could anyone recommend
some
helpful sources (letters collections, newspaper articles, etc.)?  I'm
interested in both tracing their friendship and seeing what kind of
connections
can be made between Twain's writing and Barnum's showmanship.  I've found
one
piece Twain wrote about Barnum, but aside from that my research hasn't
turned
up much.

Thanks in advance,
