(I'm more or less settled in here at Michigan; now that I've got enough work to need distracting from, blogging will continue...)
From a journal you might not follow (I don't): Mangone et al., "Technological features of 'gnathia' pottery." X-Ray Spectrometry 38.5 (2009), 386-393 [abstract].
The Università degli Studi di Lecce has digitized Studi di Antichità and four monographs published by the Dipartimento di Beni Culturali dell'Università di Lecce - Settore Storico-Archeologico, available here (once you've clicked on the number you want, you have to click on "Contents..." in the left-hand column). Also possibly of interest: Gli Album del Centro di Studi Papirologici, Papyrologica Lupiensia and Kronos; you can see the full list of scanned journals and monographs here (don't miss the E-Prints down at the bottom of the page).
We are looking forward to Michael Weiss' forthcoming (2009) books Language and Ritual in Sabellic Italy (Leiden: Brill) and Outline of the Historical and Comparative Grammar of Latin (Ann Arbor: Beech Stave). His 2009 article "Umbrian erus" is available as a pdf on his website (above).
As for books that have already come out: Josh Katz (favorably) reviews Rex Wallace, The Sabellic languages of ancient Italy (2007) in Language 85.2 (June 2009), 490-492. Katz writes, "W rightly reminds us that the corpora of ‘dead languages’ are not always closed. It is exciting when a new inscription turns up..."
...and there are, apparently, a few new inscriptions, published by Adolfo Zavaroni and Giancarlo Sani, "Iscrizioni nord-umbre del bellum sociale nella Valle di Ospitale: prime indicazioni." Klio 91.1 (June 2009), 69-103. I think I will have more to say about this article and these inscriptions, but for now I'll simply copy the summary since it doesn't appear to be publicly available:
In two sites of the Valle di Ospitale (Modena province, near the border between Aemilia and Etruria) many inscriptions written on rocks during the bellum sociale (90–89 B. C.) by rebels against Rome have recently come to light. The rebels define themselves as Umbrians, but their dialect has several particularities which drive us to distinguish it from the Umbrian of the Iguvinian Tables. The alphabet contains some special letters, but it is above all the frequent use of ligatures that characterizes these inscriptions and makes their reading often difficult. Most of them contain exhortations to revolt against Rome and form an Umbrian League. A few writings have an erotic content; others are illuminating on the main gods worshipped by the rebels. Here we present a selection of the inscriptions whose reading is more easy.[!!!]
