I've only written a few posts about Pompeii, and it's not my area of expertise, though I have taught the material quite often. There are many books, of course. The Electa Guides to Pompeii and Herculaneum are excellent, as is only to be expected. I'd definitely recommend Alex Butterworth & Ray Laurence, Pompeii: The Living City. I haven't looked inside Joanne Berry, The Complete Pompeii, but it seems likely to be impressive, and has been favourably reviewed. And there's a new book on the city from Mary Beard.
Anyway, I don't have much to say on this, but thought the date should be marked.
