Dear Group: After speaking with a third person at the library for the blind, and after being informed by the first two that no biographies of Twain existed in Braille or on tape, this efficient woman has come up wit four biographies of Twain. They've not arrived yet, which I know will send my mother into a tizzy, especially if they are all in Braille, as Braille is quite voluminous, but which biography of Clemens to you feel is the best and why? For that matter, which isn't very good? Is there anyone on this list who has written a biography of Twain? Thank you. Camy
