This text provides editions of all known royal inscriptions of kings who ruled in ancient Mesopotamia down to the advent of King Sargon of Akkad. Most of the inscriptions come from the city states of Lagsh and Umma; inscriptions from other sites are rather poorly attested. The volume includes a handful of new inscriptions recently uncovered in Iraq. Information on museum numbers, excavation numbers, provenances, dimensions and lines preserved in the various exemplars are displayed for multi-exemplar texts in an easy-to-read tabular form. Also included in several commentary sections are notes on the find-spots of the inscriptions from Lagas and references about various toponymns to be discussed in a forthcoming study of the author on the geography of Lagas and Umma provinces. Indexes of museum numbers, excavation numbers and concordances of selected publications complete the volume. The microfiches which accompany the book contan texts of selected inscriptions arranged in a 'musical score' type of format.
