The first tablet (AUAM 38.0026) came as part of the permanent loan, arranged by Lynn H. Wood, from the Oriental Institute, University of Chicago. More tablets arrived in 1951 as gift from Norwegian Seminary, then a few others in 1954 donated by Taylor Bunch. The bulk were purchased from the Hartford Theological Seminary Foundation in Connecticut with original negotiations beginning with Horn in 1973. The tablets span 2,000 years, the oldest (AUAM 73.3220) dating to ca. 2300 BC and the latest being neo-Babylonian or Achaemenid (ca. 600 BC) with about 2,000 tablets from the Ur III period (2100-2000 BC). The texts may be ordered in three genres. First and most numerous are Ur III archival documents from the administrative center of Drehem that deal with the receipt of cattle from Sumerian cities and with shipment of cattle to Nippur, with a smaller group of tablets from Umma concerned with gurush laborers who did agricultural work and dug canals. Many of the tablets contained impressions from cylinder seals that served as a form of identification, their impressions guarding against illicit alterations. Old Babylonian period (1800-1600 BC) tablets included field rental contracts and letters. Archival tablets demonstrate the social and economic history of the period. A second group of texts contain monumental inscriptions, including a stone slab with two royal texts, bricks with a royal seal of Nebuchadnezzar, and clay pegs mentioning a temple construction. These latter were fixed in a temple and covered with plaster. The third text genre includes canonical compositions, used in the curricula of scribal schools, that evolved into literary canon. Others include birth incantations, some bilingual (Sumerian and Akkadian) lexical texts, and some mathematical texts (sexagesimal multiplication tables).
A few tablets were published by Edmond Sollberger and Albrecht Goetze;
Sigrist spent three successive summers copying Ur III and Old Babylonian
tablets. V. Crawford of the Metropolitan Museum of Art in New York
City copied about 50 tablets during graduate work at Yale University.
These texts were then studied by Sigrist and Aaron Schaffer of Hebrew
University. C. Kühne of Marburg publish 20 Old Babylonian tablets.
D. Weisberg of Hebrew Union College and J. Brinkman of the Oriental
Institute plan the publication of the neo-Babylonian material.
