I've read a lot more than these, but the standouts in my collection are:

Wrestling Tough - Mike Chapman
Best Judo (can't remember the author's names, but this book is everywhere)
The Art of Expressing the Human Body - "Bruce Lee"
More No Holds Barred Fighting: Killer Submissions - Mark Hatmaker (particularly the first part of the book before the techniques)
Fighter's Fact Book - Loren Christenson (it's got a lot of good ideas, I like that it's just a collection of good ideas)
Championship Fighting - Jack Dempsey
The Straight Lead - Teri Tom
The Sabaki Method (can't remember author's name either)
Capoeira: Roots of the Dance, Fight, Game - Nestor Capoeira

other than that I'm mostly a fan of videos
