The Middle English Dictionary is a dictionary of Middle English published by the University of Michigan.
It comprises roughly 15,000 pages with a comprehensive analysis of lexicon and usage for the period 1175–1500, based on the analysis of over three million quotations from primary sources.
The first installment, "Plan and Bibliography", containing a list of Middle English texts used for the dictionary, was published by Hans Kurath and Sherman Kuhn in 1954.
[2] More fascicles were published in numerous volumes (in alphabetical order) over the next several decades.
[3] In 2007, the full dictionary was made freely available and searchable online in an HTML format.
