Dear Steve, 
I enclose a copy of the recently completed typescript on 
Elmer's post-20,000 collection numbers for your library. I am 
anxious to obtain more of the Elmer notes and, as soon as I hear 
from others and figure where the most complete typescripts are, 
I will decide how to proceed. In the meantime I am delighted to 
hear that a set covering 7037-18477a is available at Harvard. 
Thanks for taking the trouble to locate this. 
With best regards, 
AAN
