The latest American Journal of Archaeology (113.1; January 2009) is out. There is one article on Pompeii:
J. Theodore Pena and Myles McCallum, The Production and Distribution of Pottery at Pompeii: A Review of the Evidence; Part 1, Production, pp. 57 - 80.
By (what seems to me, at least) remarkable coincidence, I have just been reading Pena's article in JRA 20 (2007) on the tituli picti from Pompeii which suggests that Sicilian producers had a much greater share of Pompeii's wine-market than hitherto thought.
