Mike's book - penny dropped and KR textbooks

I am analyzing text book resources and teaching curricula addressing some
gaps, and found Mike Bergmans; Book!  Btw- has anyone have suggestions for
AI KR textbooks? I d like to prepare a reading list, and specifically
address the gaps in current curricula-

I was either not aware, Mike that you wrote a book on KR, or I was aware
and forgotten

So for those who may not be aware, or might have forgotten Mike B on this
list wrote a book on the subject
which is now available on paperback!

why did you not announce this important price reduction, does the paperback
have the same content as the expensive springer version?

I am accessing it through a Library subscription and must say that
I have a completely different epistemological take on some things, Mike, i
disagree with some of things you write
but dont have time for lengthy arguments now. will bring up issues as the
opportunity comes up :-)

Now I understand where the fat list of references  you shared with the
group on Zotero comes from :-)
Thanks!
