To the resources for the Sabellic languages add Crawford 2011, which refers to the epoch-making three volume Imagines Italicae, a corpus of almost all the inscriptions in the Italic (i.e. what I call Sabellic) languages—the Tabulae Iguvinae are not included. Most texts are illustrated with a photo and there are many new readings based on autopsy.
