Tommaso Gramigni writes to alert us to the publication of a catalogue of medieval inscriptions from Florence and its surroundings, which derives from his PhD research at University of Florence. It is presently openly available online (PDF) and will soon appear in print from Firenze University Press: Iscrizioni medievali nel territorio fiorentino fino al XIII secolo.
Tommaso also alerts us to his blog, Epigrafia Medievale.
