Bertholy list of references

With the recent interest in Bertholy, I was wondering if we could compile a reference list of Bertholy's books and articles. If people could add in references that they are aware of, we could get a complete list of his books/articles hopefully. Below are some that have already been brought up:

Books:
The Bertholy Method

Articles:
Golf 23:51 1951
Golf Feb. 1975
Golf Mar. 1975
Golf Feb. 1976
Golf Jan. 1979

If people could add in what they know, we could eventually get a pretty complete reference list that we could use to gain insight into Bertholy's teachings. Maybe we could even post that list on the SAGF home page.
