The Thesaurus Linguae Graecae (TLG) is a research center at the University of California, Irvine. Founded in 1972 the TLG has already collected and digitized most literary texts written in Greek from Homer to the fall of Byzantium in AD 1453. Its goal is to create a comprehensive digital library of Greek literature from antiquity to the present era.
Since 1985, the TLG Digital Library has been disseminated in CD ROM format. The most recent edition (TLG E) was released in February 2000 with 76 million words of text.
In April 2001, the TLG became available Online to subscribing institutions and individuals. The web version currently provides access to 3,700 authors and 12,000 works, approximately 91 million words. It is updated quarterly with new authors and works.
Information about the authors and works included in the TLG Library is stored in a database, known as the Canon of Greek Authors and Works. The full Canon is open to the public and can be searched on the TLG site.
Non-subscribers can access an abridged/trial version of the TLG corpus (click on Try out the Online TLG). The abridged version has the same search capabilities as the full version but allows browsing and searching with a representative selection of texts.
