The current issue of the _Mark Twain Circular_ offers a three-disk set:
Twain's World, Like the Dickens and Much Ado About Shakespeare -- for
$49.95 ordered directly from the Bureau of Electronic Publishing, Inc.,
141 New Road, Parsippany, NJ 07054 (The phone number is 201-808-2700).
You can buy the same package from Tiger Software for $10 more.  The Twain
disk by itself sells for anywhere from $25 to $39, so the three-disk deal
is a good one.
