The Dictionary of Medieval Latin from British Sources ("DMLBS") is a lexicon of Medieval Latin published by the British Academy. The dictionary is not founded upon any earlier dictionary, but derives from original research. After decades of preparatory work, work on the dictionary itself was begun in 1965, and it was published in fascicules between 1975 and 2013. In 2016 the complete work was put online. A consolidated reprint in three volumes was published in 2018. Source: Wikipedia (en)
