DiY Learning, "Just Because"

You don't have to be a registered student to go back to school if you just want to keep learning for its own sake. To start, here's a short list of websites that function as clearinghouses for online learning tools, wiki sites & open courses/lectures:

• Open Culture is the site I'll go to first. It has an enormous array of online resources in many topics, and the site itself is easy on the eyes.
• Free video Lectures features academic lectures delivered by university professors.
• MIT's open course ware site contains a mind-boggling list of options in humanities and sciences.
• Open Learn is a British open university site with much of the same comprehensive content.
• Stanford offers courses via iTunes and Berkeley's webcast service enable students to subscribe to regular feeds.
• Wikiversity allows users to contribute content as well as study it.

If you prefer offline options, check out the Great Courses series. Most library systems carry at least some of their offerings.
