might someone have a link to where a used copy might be found?

I just checked that book out of the library yesterday. You might want
to check your local library. Just for the fun of it I checked WISCAT
(www.wiscat.net) to see how many libraries in Wisconsin have this book.
It turns out 35 libraries in Wisconsin have this book. You may want
to check your local library(ies). It looks like it is a popular
library book.

If not, let me know and I can help you out. What page are you in need
of a copy?
