The Imago II Project, 1997-2000, digitized the Alessandrino Cadastre, the Urban Roman Cadastre, a selection of the Gregoriano Cadastre including the 600 most important towns of the Papal State, the carthography of the old rural Cadastre, Roman parchments with, often. abstracts ("regesti") included. Some of the more useful registers are digitized too: the alphabetical registers of Roman notaries; some ancient registers of the "Tesorerie provinciali". Finally, some precious items as the manuscript of "Liber Regulae".
