I just received my copy and after reading the preliminaries I went 
directly to a listing for Karl Bædeker.  I have used the Handbook for 
Travelers (many editions) throughout "Twain's Geography" and was curious 
about any correspondence between Alan Gribben's listing and my own. 
There is much disparity between publishing dates, but then the Handbooks 
went through many editions and I have been limited to on-line 
availability.  Anyway, Bravo on this achievement.  It calls for some 
more digging on my part.  The guidebooks serve as control observations 
against Twain's.
