The OED, now with more OE!
Old English in the OED - June 2002 Newsletter - Oxford English Dictionary
The revision of Old English material in the Third Edition will be thoroughgoing. Every single Old English quotation, whether already in OED or newly added, is being checked against the most recent reliable edition of the text, with new bibliographical details and additional context being given where appropriate. Dating of quotations has been radically revised, with NED’s assumed composition dates replaced by a simple threefold division of all pre-1150 quotations into ‘early OE’ (up to 950), ‘OE’ (950-1100), and ‘late OE’ (1100-1150), based firmly on manuscript dates as agreed by the most recent scholarship.
I’m thinking of ponying up for an individual subscription to the online edition as my holiday present to me this year. It’s spendy ($295), but oh-so-tempting.
