The Dictionary of Old English (DOE) defines the vocabulary of the first six centuries (600 - 1150 A.D.) of the English language, using today's most advanced technology. The DOE complements the Middle English Dictionary (which covers the period 1100 - 1500 A.D.) and the Oxford English Dictionary (which documents the development of the English language to the present), the three together providing a full description of the vocabulary of English.
The Dictionary of Old English Web Corpus is an online database consisting of at least one copy of every surviving Old English text. In some cases, more than one copy is included, if it is significant because of dialect or date. As such, the DOE Web Corpus represents over three million words of Old English and fewer than a million words of Latin, or almost five times the collected works of Shakespeare. The Web Corpus is compiled as part of the Dictionary of Old English project at the University of Toronto.
