The "Index to VOLUMES I - II - III" is dated July, 1935.
"Bulletin No. 1[ two Klopsteg articles] is dated July, 1935.
Were there later Indexes published? If so, what Month and year.
Were there other Bulletins published? If so, what Month and year.
Was there a "regular" issue published every month from August 1931- January - 1937?
My collection is 2/3rds complete and I don't have sufficient issues to answer these questions.
The lack of advertising in the July, 1935 Bulletin and July, 1935 Index suggests there may be a July, 1935 regular issue as well. So, were the Bulletins and Indexes supplemental or published in lieu of the regular, monthly issue?
Confused yet?
