I was browsing in a used bookstore and came across two booklets by R.M. Barnett on different aspects of Judo. Each of these booklets were priced at $30 a piece which is a little high for about 80 pages. I wrote the author's name down so that I could do a book search online but I have found no information. Does anyone know anything about R.M.Barnett and his books on Judo? One of the books had a copy right of 1972.
