Here's a little breaking news: Today, Google has launched YouTube EDU, which centralizes the content from over 100 universities and colleges (get list here). This robust collection gives you access to lectures by professors and world-renowned thought leaders, new research and campus tours. At the moment, you can access over 200 full courses from leading universities, including MIT, Stanford, UC Berkeley, UCLA, Yale and IIT/IISc. And it's all searchable within YouTube EDU.
I plan to follow up with a more extensive piece soon. But I just wanted to get the word out and let you start checking it out. If you have any first impressions, please let us know what you think in the comments. Nice work Youtube!
Lastly, if you want to download hundreds of free university courses (mostly in audio) to your computer or mp3 player, check out our collection of Free University Courses here.
