Burgess Publishing Company published these letters from 1935 until at
least
1973. Several universities have collections of the letters. Here is an
indication
of the partial holdings in the Stanford University Medical
Library.
For many years (probably late 50s and early 60s) my father served as
editor for the distribution of these letters to the "members" of the
Club.
To be a member, the urologist had to contribute at least one letter to
the
membership each year. My father's secretary transcribed the letters
and
sent them to the publisher, which distributed them to the members. The
frequency depended on the number of active members. In the two volumes
I
have (1967-1968 & 1970), there appear to have been 2-4 communications
per
month.
