The now complete Lexicon Latinitatis Nederlandicae Medii Aevi (Dutch Dictionary of Medieval Latin) forms part of the project of the Union Académique Internationale to replace the old Glossarium of Du Cange by a set of modern national dictionaries of medieval Latin. The dictionary covers the period up to the end of the North European Middle Ages. Its sources are those texts, written by Dutch authors or on Dutch territory between c. 800 and 1500, which have been printed, and as such include accounts as well as chronicles, lives of saints, and philosophical and theological treatises. A choice of representative texts of each literary genre has been treated by computer to complete the material.
