Three Standard Accession Books: the official record of each volume added to the San Francisco County Medical Society Library
from March 12, 1909 to October 22, 1945. Identification of the institution was aided by a 1944 letter found between the pages
of one of the volumes, addressed to F. L. Reichert, M.D., San Francisco County Medical Society. Dr. Reichert was listed as
the Librarian in the Society's Bulletin.
