In response to Roberta Warren's question about ordering tapes of the
Tribute to Mark Twain program, they can be ordered directly through the C-
SPAN site at:

http://www.c-spanstore.com/167535.html

It says the regular price is $60 but it's offered at a sale price of $24.95.
I
don't know when the sale ends.  They also provide this information on their
Customer Service page:

Besides ordering online you can also order:
