In 1923, the International Union of Academies (www.uai-iua.org) launched the « Dictionary of Medieval Latin » whose goal was to replace the Charles Du Cange’s Glossarium Mediae and infimae Latinitatis (17th century). The « New Du Cange » was meant to become a modern and scientific general dictionary of Latin as was used in Europe from the 9th to the 12th century. In order to perform this arduous task, a European network of Medieval Latin lexicography was brought into being. A century later, the project has remarkably evolved : the Novum Glossarium and the national UAI dictionaries, which form its supplement, help users to understand medieval culture without resorting to classical Latin dictionaries, but still did not completely replace the old Du Cange’s Glossarium. The process of writing the Novum Glossarium (IRHT-CNRS), which has to account for more than 10000 bibliographic references, went from entirely manual (traditional paper slips) to wholly computer-driven as a result of introducing methods of exploitation of the digital text corpora. Apart from the retro-digitization of the Glossarium and those fascicles of the Novum Glossarium that have been published up to now, the outlook for the electronic publication of the dictionary is now more clear than ever. The Index scriptorum of the Novum Glossarium after being converted to SQL and indexed, should serve as a bibliographic database. The ongoing digital revolution makes it even possible to conceive a « New New Du Cange », which would be now developed in a framework of European and national projects, and to fulfil the dream of a truly universal dictionary of Medieval Latin.
