A good book to learn about Ross if you're into that type of thing is "When Boxing Was A Jewish Sport" which details that late 1920's early 1930's era in which almost all the top fighters were Jewish. It goes into great detail on Barney Ross and another great fighter Benny Leonard. Last time I went to Barnes and Nobles they had it and I bought it at a Borders a short time before so it shouldn't be to hard to find.
