Galen produced more work than any author in antiquity, and may have possibly written up to 600 treatises, although less than a third of his works have survived. His surviving work runs to around 3 million words. Karl Gottlob Kühn of Leipzig (1754–1840) published an edition of 122 of Galen's writings between 1821 and 1833. His edition, which is the most complete, although flawed, consists of the Greek text with facing-page Latin translation. The text and translation are mainly taken from the edition of Chartier 1638—39, Paris. Kühn's edition runs to 22 volumes, 676 index pages, being over 20,000 pages in length. More modern projects like the<unk>  Medicorum Graecorum have still to match the Kühn edition. A digital version of the<unk> , largely taken from Kühn's edition but using newer editions where available, is included in the Thesaurus Linguae Graecae, a digital library of Greek literature started in 1972. Another useful modern source is the French Bibliothèque interuniversitaire de santé (BIU Santé).
