Hans-Werner Guesgen's PhD thesis on CONSAT has been published as a monograph. I
believe the publisher is Prentice-Hall.  (I just saw an advertisement
blurb yesterday but, sigh, no longer have it.)

There is also a book about Babylon, the expert systems toolkit (or "workbench")
developed here at the GMD.  It was published, in German, by Addison-Wesley
this year.  An English translation is in the works, but I am not quite sure
when it is expected to be available.   Babylon runs on a variety of
operating system and hardware platforms, including Symbolics, Macintoshes,
Suns (and other Unix workstations) and, I believe, PC compatibles.
