I did read this article.  It is interesting in that the author
connects Clemens's relationship to Isaiah Sellers and the guilt
Clemens expressed over lampooning the old pilot in print. His theories
are not that far removed from some that Forrest Robinson put forth in
AUTHOR CAT. He also discusses the historical usage of pseudonyms.
Whether or not one agrees with the theory, I am glad to have the
article in the reference files.
