9 W. W. Hallo was the first to use this term by applying it to such compositions as "the Nippur homicide trial" and "the rape of a slave girl and the divorce trial" (The Slandered Bride, in: R. D. Biggs/J. A. Brinkman [eds.], Studies presented to A. Leo Oppenheim [Chicago 1964] 105, repub. in Toward the Image of Tammuz, 198 ff.). He later returned to the question of genre and explained that such documents are qualified as literary because they are preserved in multiple copies, grouped on collective tablets, and formally distinct from actual juridical documents by the absence of witnesses and date (A Model Court Case Concerning Inheritance, in: T. Abusch [eds.], Riches Hidden in Secret Places. Ancient Near Eastern Studies in Memory of Thorkild Jacobsen [Winona Lake 2002] 141-54). 10 See P. Steinkeller, Seal Practice in the Ur III Period, in McG. Gibson/R. D. Biggs [eds.], Seals and Sealings in the Ancient Near East (Malibu 1976) 48-49. 11 Stephen Lieberman, at the time of his untimely death, was preparing (in collaboration with W. W. Hallo) an edition of the model contracts and model court documents, as a part of what he called the Manual of Legal Forms. However, additions continue to be made to this corpus: see Hallo, A Model Court Case, and J. Klein/T. M. Sharlach, A Collection of Model Court Cases from Old Babylonian Nippur (CBS 11324), ZA 97 (2007) 1-25. Two unpublished texts, YBC 11121 and NBC 7800, are related directly to the collection of model contracts: they are two "Sammelurkunden containing contracts of various kinds" (see W. Bodine, A Model Contract of an Exchange/Sale Transaction, in T. Abusch et al. [eds.], Historiography in the Cuneiform World. Proceedings of the XLV e Rencontre Assyriologique Internationale [Bethesda 2001] 42). 12 The only witnesses cited in the document here published are those which are attested in § 41, where the names are part of the literary tradition of that particular contract.
