My library has most of John Stevens books, and other text and video of many of O'Sensei's students. If you start to study the many teachers who were students of O'Sensei, don't forget to find the video with Hikisuchi, Michio sensei in Iwama, video make in 1988. Saito Sensei, the protector of Iwama, comes to teach in America, west coast mostly.
Many books eventually relate to pressure points, manipulation, and use of Chi/Ki. If you see simular uses of these things in Aikido, don't be surprised.
Right now, there is no definitive book of Chi/Ki differentiation for men and women, but with all the studies going on, something should come out soon.
