This volume continues the systematic edition of the unpublished Bo-texts deposited in the Museum of Ancient Anatolian Civilizations in Ankara. As in previous volumes, the tablet fragments are presented in both photographs and transliterations, with succinct philological notes explaining particular forms and relevant text variants. Direct joins with fragments in other museums are shown through digital image processing. Most of the fragments dealt with here are of the usual religious nature—predominantly ritual, festival, cult inventory, and oracular texts. Two fragments provide additions to the genre of royal instructions, while other fragments with the Ullikummi myth, an Old Hittite land grant, a list of towns, a Hattian text, and a medical text represent further text varieties. One small fragment is of special interest because it preserves two distinct layers with cuneiform script in different hands. Each text edition is accompanied, wherever possible, by information about its assignment to a Hittite text or text genre, the date of the composition, the fragment’s measurements, and previous bibliography.
