YES GOOD!! There is so much out there and it’s definitely a huuuugely daunting process to start. I’m going to recommend littlelansky‘s Book Rec List first, because she’s read more than I have
Are you looking for books about the mob and the families in general, or are you looking for biographies about specific people? Most of what I’ve read have been biographies specifically about Charlie, so I can’t really speak to many books about the New York mob in general. But I really recommend Tough Jews as an excellent read. It gives a good look at Murder Inc. and the Jewish gangsters, whose contributions are often downplayed in a lot of Italian-centric books. It also has a lot of literary value as a well-written and emotive book. At times it can be a little more literary than historical, but that’s something that appeals to me personally, because I like the combination of Rich Cohen’s excellent prose and perspective and how he uses that to reconstruct Murder Inc. and its members and their experiences.
The more general books are first on the book rec list, and while I haven’t read them myself and can’t really speak to what they’re like, littlelansky majored in history and has a really good sense for what’s historically useful and what isn’t, so I trust her judgment
