A review of Andrew Hoffman's _Inventing Mark Twain_, written by
David S. Reynolds for the New Tork Times Book Review (April 27,
1997), is online at the New York Times site:

Never the Twain Shall Meet

If you haven't used the NY Times site before, registration is
required for access.  Registration is free for users within
the United States, but I believe there is a fee for users from
non-U.S. domains.

There are also links at the bottom of the review to seven
other articles about Twain from the Times archives.
