The corpus of texts written in the
Hittite language is indexed by the
Catalogue des Textes Hittites (
CTH, since 1971). The catalogue is only a classification of texts; it does not give the texts. One traditionally cites texts by their numbers in CTH. Major sources for studies of selected texts themselves are the books of the
StBoT series and the online
Textzeugnisse der Hethiter.
