Dwight-
I might give Tim Whelan (Photography Books and Prints) in Rockport, Maine.
He's very good at finding out of print and hard to find books.
His e-mail is <tim@midcoast.com>
You might also try an inter-library loan. I sometimes can get these out of
print books through a library search. One doesn't get to keep it on the
shelf, but you can glean the info you need and save yourself the room.
Good luck-
Jon Bailey
