I have well over 100 BJ books +the complete collection of Blackjack Review magazine and most of the Blackjack Forum issues (still working on getting those) and some other general gambling books.
I am too lazy to dig them all out and list them. Here is a quick list off the top of my head of some of the more rare or valuable ones.
Blackjack for profit, Snyder (extremely tiny!)
Blackjack formula, Snyder
Winning without counting, Wong (First Ed. Autographed)
Professional BJ, Wong (First Ed.)
Wong's early BJ newsletters, Wong (just a few copies)
Beyond counting, Grosjean (read too many times, tattered and worn)
Read the dealer, Forte
Casino game protection, Forte
The big player, Uston
Uston on BJ, Uston (I didn't think this was that rare but listed it for Zengrifter)
Gambling times magazine (All the issues with Uston articles)
Playing BJ as a business, Revere (First Ed.)
Turning the tables on Las Vegas, Anderson (First Ed.)
How to win at BJ, Charles Einstein (68? Ed. can't remember)
Cheating at BJ, Marks
Cheating at BJ squared, Marks
Blackjack a professional reference, Dalton
21 counting methods to beat 21, Koko Ita
Silver Fox BJ system, Stricker
Card counters guide to Casino surveillance, Cellini
And I saved this one for last.
Blackjack'$ winning formula, Patterson (a book before he went nuts and started pushing TARGET.)
Not really rare or valuable to collectors but its rare for me to have a Patterson book.
I could probably come up with some more but I'm lazy.
Just thought of one more
Hollywood BJ, Dave Stann Aka HollyDeezy WTF? (rare because it is so new and also so painful to read that few should have it)
