Just wanted to share a marvelous find that is FREE
iTunes, the computer application, has a section called iTunes U (iTunes University). It has thousands of classes that are all free on just about any subject you can think of. You can download the iTunes computer application, and register even if you don't have an iPhone, iPad or any other device.
Once you've downloaded the app to your computer, you can navigate to iTunes University and start browsing through the classes.
I just downloaded an entire semester from Yale University on the History of Roman Architecture. AND IT WAS FREE.
Can you tell I'm excited??
