I never said "the book I refer to" should be put first on any list of
definitive biographies, but to disclude it altogether smacks of a certain
type of censorship no reasonable academic should embrace.  I fear you and Mr.
Bird have gone overboard. The gentleman who requested a list of definitive
bios on Twain might by now think the two of you slightly offbase; I certainly
do.
Hoffman's book is an interesting read, regardless of your detractions.
Please, no more sparring.
Warmly,
Richard Salassi
