The TITUS project (“Thesaurus Indo-germanischer Text- und Sprachmaterialien”) was founded in 1987 with the aim of co-ordinating the efforts to establish databases of written texts in ancient Indo-European (and adjacent) languages and to create comprehensive electronic corpora of these languages. Since 1995 the steadily growing materials it hosts have been accessible online (cf. http://titus.uni-frankfurt. de/texte/texte.htm), an interactive retrieval engine providing elaborate search facilities (cf. http://titus. fkidg1.uni-frankfurt.de/search/query.htm).
