A while back, I wrote about free books online.  Another great resource available for free is iTunesU.  Universities from around the country, including MIT, Stanford, UC-Berkeley, Yale, Reformed Theological Seminary, and about 30 more schools, offer free lectures – even entire free courses – for download oniTunes.  I’ve recently listened to Thomas Friedman talk about the ideas behind his book The World Is Flat (liked it so much I went out and bought the book) and Merlin Mann of 43 Folders speak about managing your time and attention.  Great stuff.  And now you can download free content from PBS through ITunesU.  These are incredible materials for you autodidacts (like me) who couldn’t fit all the classes you wanted to take into your college schedule.  And, if you’re still like me, now you can add unlistened-to lectures and unwatched documentaries to your guilt list of unread books.
