I do not normally repost stuff from others but saw a post on this today and thought I would share the information I found in it
I’m not a fan of iTunes, especially since I use a WP7 which forces me to use Zune. But I do have to admit that one particular feature of Apple’s online media store is absolutely wonderful, and well worth exploring.
That feature is called iTunes U. The “U” stands for University, and it’s a scheme whereby dozens of the world’s top universities make thousands of lectures available online. Most of them are completely free, and can be accessed by anyone, regardless of whether you’re a student at the university concerned.
The lectures cover every subject under the sun, and because they were produced within leading universities it’s a fair bet that they’re accurate and trustworthy.
To use iTunes U, the only downside is that you’ll need to install iTunes on your PC and sign up for a free account. The download, from http://www.apple.com/itunes, is around 75 MB. Once you’re done, head to the iTunes Store and then click on the iTunes U button in the top menu bar. You’ll be glad you did.
Hopefully that information will help someone find a lecture they may be looking for.
