The person who inquired about criticism on _PW_ should also check out a
collection of essays entitled _Mark Twain's Pudd'nhead Wilson_, edited by
Susan Gillman and Forest Robinson, Duke UP 1990.  Also, I believe that the
journal _Nineteenth-century Literature_ has full-text articles on-line, and
I'm certain that there have been a couple on _PW_ in the last 8 years or so.
