Its goal is to create a comprehensive digital library of Greek literature from antiquity to the present era.

The full Online TLG continues to grow, but currently contains over 10,000 works associated with 4,000 authors (as of 2013). Most of that corpus, however, is avalable only by paid subscription. A subset (Abridged TLG) together with the bibliographical database developed by the TLG (Canon of Greek Authors and Works) is open to the public. The Abridged version contains 900 Greek works from 67 authors and uses the same search engine as the full Online TLG version.
