In the season 1950–51, the Joint Expedition of the Oriental Institute of the University of Chicago and of the Babylonian Museum of the University of Pennsylvania excavated in Nippur a cache of twenty-eight Neo-Babylonian tablets. They were found in the location TA/52, 30 cm. above level III/1 floor, and they now carry the numbers 2 NT 280 to 2 NT 307.
All but three of these texts are legal documents, the exceptions being 2 NT 306, a private letter, and 2 NT 283 and 307, the contents and paleographic features of which mark them as administrative tablets. They had been included in the cache for reasons which remain unknown. In the location TA/34 (level III/1) a tablet, 2 NT 165, was found which, because of the personal names it mentions, must be added to the present group. There is, of course, a definite possibility that the inhabitant of the house in which 2 NT 165 was found had hidden a group of valuable documents in a cache in an empty lot behind his backyard (cf. p. 70 for further discussion).
