Encyclopedias

A colleague of mine at work had a set of TKD Encyclopedias she gave me.  She was going to take them to Goodwill. It turns out there are 15 ~300 page books written by General Choi!  There were also 5 paperbacks written by Jhoon Rhee!  Although all the forms are ITF, there's a lot of really good information about TKD in general, the history, philosophy, etc.  Here's one I had not seen yet:  the 9 training secrets of TKD.  I look forward to reading these!
