USCSD has the fall schedule up, including a course on children's literature being podcast. Today's lecture is the Lion the Witch and the Wardrobe. I haven't listened to it, but usually their lecturers are good. Some however now require sign in, including Matthew Herbst excellent MMWI course, on very ancient history. Luckily his 2011 course is still there to download, and some of his other MMW history courses if you scroll down.
I also am downloading a courses on iTunes and youtube, but haven't listened to them yet. These take longer to download, and then I have to rip the videos to mp3 to listen to them.
