depending on your skill level, you may only need to learn simple non-counting basic strategy (which surprisingly 99% of casino patrons have never heard of). I would suggest:
Blackjack Bluebook II - Fred Renzey
American Casino Guide - Steve Bourie
Smarter Bet Guide to Blackjack - Basil Nestor
you can even go to a place like
www.blackjackinfo.com, get the strategy chart and practice online for free.
if you decide you want to move up to card counting, then Snyder, Wong, Schlesinger, Vancura/Fuchs etc are available.
