Deanna L. (misssteps) reviewed Bodywork for Horses: Techniques You Can Use Yourself on + 27 more book reviews
An excellent overview. There is a lot more here about training and classical than you might expect, and a lot less about massage and shiatsu. It includes information about aromatherapy, hydrotherapy and TTouch, as well. It really doesn't go in depth into any of the above (the section on shiatsu being the best, as the author is a practitioner) but refers you to other books for more information.
