Please Recommand books on PLAAF to me

Sorry to bother your guys and take up valuable space, but please
help me.

I can read Chinese (well, not much really), but it’s hard for
me to get Chinese books and I don’t know what’s accurate. So
please suggest some English books/mag./web sites on PLAAF
to me. Thanks.

Here is some related websites I know so far:
The Commonwealth Insitute – http://www.comw.org/cmp/
PLA Weaponary – http://members.aol.com/zyy/PLA/
Kanwa – http://www.kanwa.com/
Chinese Military Aviation – http://www.concentric.net/~Jetfight/
FAS China section – http://www.fas.org/
PRC vs ROC – http://www.emeraldesigns.com/matchup/military.shtml

Anybody know more?
