Info on strength training books ?

I am looking into getting some books on weightlifting. I wanted some input on what I can expect from the following books. If anyone has read them, tell me what you think of them or what may be a better choice.
Bill Pearls "Keys to the inner universe"
Mel Siff's "Supertraining"
Vince Girondas "Unleashing the wild physique"

I am also interested in books covering muscle balance and "diagnosing" imbalances in strength and structure. (like how strong should your triceps be compared to your biceps, what constitutes a "tight hamstring", should everyone be able to place their hand flat on the ground when trying to touch their toes?)
I have alot of basic bodybuilding books and would like some more info on program design, set and reps schemes etc. Thanks for the input.

my favorites have always been Bill Pearl's "Getting Stronger" (my first guide to training) and Thomas Beachle's "Essential of Strength Training and Conditioning" (one of the best science based training books).

Thomas Beachle's "Essential of Strength Training and Conditioning"

I think this a better choice than Supertraining if you want more a of a
geek book . . . it's much less ideologically and more straight forward.

Thanks, I'll have to check out the "black book" and "Essentials of strength training and conditioning"
