in addition to the excellent
Professor, the Banker, and the Suicide King, already mentioned by moose, i liked all of these quite a bit:
Cowboys Full gives a relatively thorough (for a general reader book) history of poker who also wrote
Positively Fifth Street about playing the 2000 WSOP main event. both are very readable and i remember them being well-sourced.
The Biggest Game in Town is a classic and takes the form more of player profiles and narrative excursions (which makes sense since it originally appeared as a series in the New Yorker), but also intersperses a fair bit of history throughout.
Blood Aces is a biography of benny binion and therefore a history of poker in vegas. i can't comment on quality, but it's waiting on my kindle to be read, so one of these day's i'll get to it.
The Odds profiles sports bettors and most of the action takes place in vegas. one of those profiled is a young alan boston who is extremely bright and beyond entertaining. gives a really good feel for the sportsbook culture of vegas.
When the Mob Ran Vegas is pretty self-explanatory. obviously plenty of pretty amazing stories. hard to separate fact and fiction from this time period, but it's a good read.
Whale Hunt in the Desert is a fucking riot. Many hilarious degen stories from Steve Cyr, casino host to high stakes players. he was on the 2+2 podcast a couple of times and has a great dry sense of humor.
