Many universities and colleges have their own iTunes U sites, including my own, Duke University, which has an impressive iTunes U site with lots of materials of interest. A lot of it consists of audio materials from conferences or public lectures, but some is created specially for the web. Here's the link to Duke's iTunes U site:
Duke on iTunes U
The links on that page will encourage an iTunes application to launch, so you will need to have iTunes installed if you don't have it already.
So what's available in our area over at Duke's iTunes U site? If you look to the left on the main menu, you will see Religion listed as one of the topics. Included under this topic is one thing that I have mentioned previously, the link to Dale Allison's 2008 Kenneth Clark Lectures. See also Carol Meyers on Women in Scripture; Beyond the Da Vinci Code with Bart Ehrman and Richard Hays; and Two Views of the Resurrection with Gary Habermas and Joel Marcus. And now also the NT Pod, with me!
Many thanks to Stephen Toback and Tom Freeland for their help in introducing me to the world of iTunes U and adding the NT Pod to its service.
