The history of the Hospitallers on Rhodes (1310-1522) is still subject to intensive research, but the main printed edition of sources for the Hospital of St John, the Cartulaire of Delaville, ends in 1310. The Project therefore aims at providing a calendar of sources, transscripts from unprinted materials and a gateway for secondary works and links. It is located at the "Arbeitsstelle für die digitale Edition mittelalterlicher Quellen" at the Centre "Geisteswissenschaften in der digitalen Welt" of the University of Hamburg.
