A Question

So, I have arranged to do a directed readings next semester on the military religious orders during the middle ages -- Hospitallers, Templars, Order of Santiago, and the Knights of Malta if we can work them in. So, my question for any historically-minded readers I have is, what good works on the military orders, especially ones my professor might not pick out, are there? What would be a good book or collection to suggest for the readings? Anybody have any suggestions?
