I am looking for superceded editions of the Lock Haven, PA 7.5' topo dating
from 1940-1965.   I already have the 1986 7.5' and 1921 15' topos.  A geography
professor here at Rutgers would like to be able to see them and photocopy a
portion of the map.  Does anyone keep the older editions and be willing to
lend them on ILL?  I already know that the historic USGS microfilm only has
the 1965 7.5' topo on it. (thanks to Nancy Kandoian)
Thanks in advance.  Please reply directly to me.
