Resources for medieval deeds of arms

I have a great interest in jousts, tournaments and other deeds of arms, and so does Will McLean at A Commonplace Book. Recently he's had two posts of interests pointing to late medieval rules for such things, one showing the way to a recent scholarly article on 15th century German tournament rules, the other listing and excerpting some treatises on judicial duels.

Enjoy!
