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, Jim O'Loughlin University at Buffalo
