The Thesaurus Linguae Graecae (TLG®) is a Special Research Project at the University of California, Irvine. It is administered by a Director who reports to the UCI Vice Chancellor for Research.
Founded in 1972 the TLG represents the first effort in the Humanities to produce a large digital corpus of literary texts. Since its inception the project has collected and digitized most texts written in Greek from Homer (8 c. B.C.) to the fall of Byzantium in AD 1453 and beyond. Its goal is to create a comprehensive digital library of Greek literature from antiquity to the present era. TLG research activities combine the traditional methodologies of philological and literary study with the most advanced features of information technology.
