Oxford University now has an official podcasting presence on iTunes, albeit a small one. It's hard to know whether this is part of a wider university initiative, or whether it's just one academic program acting on its own (it seems to be the latter), but you can now listen to a series of four Oxford lectures on Old English language and literature in historical context. In short, we're talking about things medieval. Captured straight from the classroom, the lectures are presented in a lively way by Dr. S. D. Lee. Give a listen here.
