The dictionary is now available online to researchers in a wide range of fields (Classics, Medieval Studies, Modern Languages), usually via an institutional subscription. I take the opportunity to cross-refer to the lower-spec. but non-subscription-based version of the DMLBS with the Logeion platform at UChicago.
This is a commercial online version of the DMLBS, which Brepols Publishers offer in connection with their suite of dictionaries and which they link to other databases (e.g. of texts). The licence was granted by the British Academy, since the Academy is the copyright holder for the dictionary.
