In these pages, the Museum of Archaeology and Anthropology of the University of Pennsylvania and the Cuneiform Digital Library Initiative (CDLI), an international research project based at the University of California, Los Angeles, present a database of the inscribed objects in the Philadelphia collection. In an initial phase of this collaboration funded by a grant from by the Andrew W. Mellon Foundation and directed by Stephen J. Tinney, Professor of Assyriology at Penn’s Department of Near Eastern Languages and Civilizations, Penn staff digitized the Nippur and Ur collections of the museum, in subsequent phases the remainder of the holdings, particularly a stunningly rich trove of royal inscriptions.
