Besides THE book (Klabnik/Nichols), the ones from O'Reilly, Pragmatic and Nostarch (for Rustaceans, Gjengset, in particular as a 2nd book) are excellent to superb. I might have missed a few, these were the ones from 3 public library systems.
Just look for 2nd eds on THE book and Oreilly's Blandy et al. Course i saw one from Wrox that was a pass.
