During these summer months, we've been busy rummaging around the internet and adding new courses to our big list of Free Online Courses, which now features 1,150 courses from top universities. Let's give you the quick overview: The list lets you download audio & video lectures from schools like Stanford, Yale, MIT, Oxford and Harvard. Generally, the courses can be accessed via YouTube, iTunes or university web sites, and you can listen to the lectures anytime, anywhere, on your computer or smart phone. We didn't do a precise calculation, but there's probably about 35,000 hours of free audio & video lectures here. Enough to keep you busy for a very long time.

Right now you’ll find 133 free philosophy courses, 85 free history courses, 120 free computer science courses, 71 free physics courses and 55 Free Literature Courses in the collection, and that’s just beginning to scratch the surface. You can peruse sections covering Astronomy, Biology, Business, Chemistry, Economics, Engineering, Math, Political Science, Psychology and Religion.

Here are some highlights from the complete list of Free Online Courses. We've added a few unconventional/vintage courses in the mix just to keep things interesting.
