You can see the type of "thing" I do in Twain scholarship in any of the
Oxford
Twain series.  I do have some interesting new things that will go in my Vol
II
of my Twain and his illustrators book (coming out this fall), but there are
other pieces along the same line.  Would you be interested?  I can send some
things by snail mail if I hear from you.  I believe we have corresponded
before about this but we can try again.
