You really don't need any more books for basic to advanced counting - that is the A-list. The B-list is long.
Get Uston on BJ by K. Uston, its a classic.
One of the best AP books I read in years recently was Bob Dancer's Million Dollar Video Poker - it doesn't teach any BJ (nor VP for that matter) but its really excellent.
Beat The Dealer by E. Thorp is required reading.
Barfy's You've Got Heat is good, and I'm hearing good reviews of Snyder's new Big Book of BJ.
The DVD 'The Hot Shoe' is good.
If you ever plan to play tournaments Wong's Casino Tournament Strategy is a one-of-a-kind.
Grosjean's Beyond 21 is also one-of-kind

Two Free Online BJ Books -
Clark Cante's 'BJ Therapy' (quirky)
http://www.bjrnet.com/archive/BlackjackTherapy.htm
TH Systems (valid, not better)
http://www.bjrnet.com/thop/T-H_Basic_Blackjack.zip
Wong's Pro BJ (too many charts)
Blackwood's Play BJ Like a Pro (over-emphasizes HO2)
Renzey's Blue Book (little thats new)
Scoblete's Best BJ (decent)
Carlson's BJ for Blood (betting sytem out-dated)
Uston's Million $ BJ (good stories, too many charts, advanced system overly complicated))
Wong's BJ Secrets (fodder for ideas but old tricks)
Anderson's Burning the Tables ('ultimate gambit' is too restrictive)
Malmuth's BJ Essays (Definitive text on Cut-Off Tracking)
What system are you using? zg
