The so-called cult inventories are of fundamental interest for our understanding of the Hittite local cults. They contain lists of temple inventory, offerings and personnel, but they succinctly describe religious festivals as well and sometimes even offer descriptions of idols. This study contains a text edition of many significant cult inventories, mainly connected with the Hittite 13th-century cult reorganization. It also uses these and other texts to draw a picture of the background and the administrative and geographic aspects of this operation.
