I was looking for an Anglo Saxon grammar by Michael Drout on Archive.org and found two of his lecture series are there.
From Here to Infinity, about science fiction.
Tolkien and the West.
and YouTube has his lecture series on Fantasy literature.
an excellent teacher.
Quick: Download before the copyright cops find it is there (or buy them if you can afford them).
By the way, his grammar book, King Afred's Grmmar, is on line here.
and you can audit his course Introduction to Anglo Saxon at Signum University (for a small fee).
