Volume 19: January – December 1960
Volume 20: January December 1961
Volume 21: 1962 – 1963
Note: I am naming these like they are named on the front of the journal. There is no indication as to the month of publication.
After a long delay, Volume 21 continued even though it was now 1963. Hints about the reason can be found in the journal below.
Volume 22: September 1964 – July 1966
After another long delay, Robert Stone becomes the editor. Note that the first three issues below are labeled on the front pages as volumes 21-1, 21-2, and 21-3, which is very confusing since those same labels are already used above. However, at some point Robert realized that the volume should now be Volume 22. The 4th journal below thus becomes Vol 22 No 4. I am labeling all the 1964 Journals as if they are Volume 22. He does not start labeling items as Volume 23 until the October issue of 1966. You will need to be careful when you reference these journals.
Volume 23: October 1966 – December 1967
Volume 24: January – December 1968
Volume 25: January – December 1969
