and then there was one... (book to find)

_Ginn Science Program, Advanced Level B_; Roy Gallant, Isaac Asimov;
Ginn (Xerox); 1973
This is the last book I need to complete my collection of all of the
books on the list of published works, and several not on the list,
that I know of.

I have several very rare titles to trade (for examples, others from
the GSP series, and/or the first two editions of _Biochemistry_ text)
or I can settle for cash...

Anyone with a copy of this book, please contact me... I will make it
worth your while.
