In a tiny surge of inspiration this morning, I googled free online history courses. I wasn't able to find the courses I want actually being taught right now, but I did stumble across a plethora of free courses taught in the past at MIT. I don't see that the lectures are available on iTunes, but there's plenty of reading material, copies of tests, and syllabi to go through if you're dying, as I am, to read more of the Greek and Roman classics and learn more about American history. Or pretty much any subject, really. Great resource for writers, I think.
