The OE period extends from the earliest records in the Germanic language known as Old English to the early twelfth century. The Norman Conquest in 1066 is often taken as the terminus ad quem, because that battle allowed the Norman-French-speaking William to take the English throne, and the subsequent political importance of French gave it the kind of importance it needed to bring about major linguistic changes in the language, so that by the thirteenth century, Old English had evolved into Middle English, bringing with it a new kind of literature.

VII. E-discussion list:
ANSAX-L@WVNVM. Founded and "owned" by Patrick W. Conner in 1985, this is one of the oldest scholarly e-mail discussion lists in the humanities.
There are now nearly 1200 members. Archived from earliest days on ANSAXDAT at Memorial University of Newfoundland. Gopher to Memorial University at St. John, Newfoundland, choose "Libraries and Electronic Publications," choose "Memorial University Library Catalogue," and follow the prompts from into the catalog; alternatively, choose "ANSAXDAT: Archive for the Anglo-Saxon Discussion List" and go from there. The latter choice is more definitively complete, because it's an automatic archive, but it was started only in April 1993. The former goes back to about 1987, but it has gaps, and has not been brought quite up to date.
VIII. Corpus in e-form:
- The complete corpus as prepared for the Dictionary of Old English project has been encoded in SGML, conformant with TEI standards, and is available from the Oxford Text Archive.
- The Anglo-Saxon Poetic Records have been encoded in HTML, however, and are available on the Internet.
