Ni 2762 & Ni 9838 (Nippur) are clay tablets that contain lines 253-274 (obverse) and 287-312 (reverse) of "Inanna's Descent to the Netherworld," a Sumerian afterlife myth. Ni. 2762 is almost entirely illegible as it only contains the ends of a few lines. Ni 9838 joins 2762, which means they are connected. These artifacts are limited in their overall contribution to the text, but are nonetheless important when combined with Ni 4200. With Ni 4200, the artifacts provide a basis for how many lines exist in the gap (missing lines).
These artifacts are located at the Istanbul Archaeology Museum (Istanbul, Turkey) and were first published by Samuel Noah Kramer, a notable Sumerian scholar. They were later republished in 1976 by Kramer in a publication commonly abbreviated as ISET II (Sumerian Literary Tablets in the Istanbul Museum, series II).
The Nippur tablets were discovered in modern-day Iraq during expeditions in the 1890s. Sketches of Ni 2762 first appeared in 1942 when Samuel N. Kramer published an article in the Proceedings of the American Philosophical Society journal. Kramer also published the text a few years later in 1944 while he was working at the Istanbul Museum on a fellowship. A sketch of Ni 9838 was published in 1963, again, by Kramer. As one can see, Kramer published the findings and contributed heavily to the translation of these artifacts.
