J. F. Niermeyer's Mediae Latinitatis Lexicon Minus is a highly practical lexicon, providing researchers, teaching staff and students in the field of Medieval History with concise, essential information. This new online edition, still the “compendious lexicon for rapid information” envisaged by Niermeyer, recreates the second print edition (2002) on Brill’s Dictionary Platform, providing French, English and German translations for every entry of a Medieval Latin concept and searches on lemma and full text, i.e. searches can be refined by century of use. All entries are contextualized with relevant text passages.
