DYABOLA Contains several databases, the most important of which is the "Realkatalog des Deutschen Archäologischen Instituts Rom," the most comprehensive database for classical archaeology. This database goes back to 1956, and succeeds the print Archaologische Bibliographie, which started in 1932 (Carpenter Periodicals DE 2 .D5). Journals, Festschriften, and collected studies are all covered; the main focus is on the Mediterranean world.
