I have been reading what I can about Koryu bujitsu for a few years now, purely from an academic standpoint, and I came across references to a book which is (for a want of a better word) a telephone directory of the Koryu schools in Japan. The book contains each ryuha's history and genealogies, etc. Sounds great doesn't it? Well, I forgotten the title and I cannot remember if I read about it here or on Ebudo (I did search through the threads on both sites but no luck). If any of you folks know what the book I'm on about, I would greatly appreciate it if you could tell me the title!
