Though not as technical as the ones previously mentioned, Brooks Johnson Coaching Manual is a good read, IMHO. Some interesting perspectives from one of the more prominent USA T&F;coaches through several decades.
Another (if you can find it – possibly old book shops) is Champions in the Making by Jordan/Spencer. Many specific and anecdotal references to the giants of the 50’s and 60’s. Perhaps a more sanitary version of something like Speed Trap.
