The Thesaurus Linguae Latinae (TLL) is produced by the Committee for the Publication of the Thesaurus Linguae Latinae at the Bavarian Academy of Sciences, which consists of an international team of 20 Latinists, with the support of more than 30 academies and learned societies from three continents. The TLL is the first comprehensive scholarly dictionary of ancient Latin from the earliest times down to AD 600. The TLL permits users to follow the development of meaning and usage of Latin words. This online database of the TLL provides access to the contents of all lexicon articles published up to 2008 (that is the letters A–M, O, P–pomifer, porta–pulso), the articles in the Onomasticon volumes (letters C and D), the Index librorum, and the Praemonenda de rationibus et usu operis, a multilingual introduction to the printed version of the Thesaurus. The content of TTL online is identical to that of the printed version of the Thesaurus. Each year the contents of the newly printed fascicles are added to the database.
