begging for a book (again)

I know you all may be getting tired of this request, but I ceep on
trying.

I have ALL of the books in Ed Seilers's list written, or edited by the
Good Doctore, save one. (And a few not on the list)
Yes, I mean ALL.

The one I don't have is:
Ginn Science Program, Advanced Level B; Asimov, Gallant; Ginn; 1973
(Teachers' Edition, 1975)

I have several items I could offer in trade, or if you prefer, cash.
Some of the items I would trade are duplicates from my collection
including two of the other volumes of the Ginn Science Program series;
either or both of the first and second edition of Biochemistry and
Human Metabolism, and/or several other items of particular value or
interest.

I have been searching daily for the last 3-4 years. Please do not
refer me to the multiple sources on the WWW as I know those sources
and that is the where my daily searches take place.

Please e-mail me if you have a copy of this book and if you are
willing to part with it. Please request what you need for your
collection, and I will try to provide it in exchange. All quotes and
offers will be considered.
