The 891 tablets, envelopes and fragments, and 37 bullae discovered during the 1993 season over Kültepe's site were found in two neighbouring houses. They belong to three of four generations of the same merchanat family. The study of this archive, still in progress, allows to reconstruct the family tree, to understand which kind of text was preserved and how the documents were classified. The main owner of the archive, Assur-taklaku, son of Alahum, grand-son of Iddin-Sîn, was active during about twenty years in Kanis. The archives cover the middle of the second half of karum level II and they end before the destruction of this level.
