Mittellateinisches Wörterbuch (MLW, Mittellateinisches Wörterbuch bis zum ausgehenden 13.
Jahrhundert) is a project for the edition of a comprehensive Medieval Latin dictionary, organised by a committee of the Bavarian Academy of Sciences and Humanities and published with C. H.
[1] The plan for a dictionary replacing Du Cange's Glossarium Mediæ et Infimæ Latinitatis originates with the Union Académique Internationale, which established a Comité du dictionnaire du Latin médiéval in 1919.
A collaboration of French and German academies was planned in 1939, but interrupted by the Second World War.
[2] Seventeen fascicles for MLW were published during 1959–1976, but work was delayed (fascicle 18 in 1985), and the second volume (letter C) was completed only in 1999.
