Today I would like to highlight Open Yale Courses on iTunes U. iTunes U is a collection of academic resources for both secondary and post-secondary schools around the world. The Open Yale Courses includes introductory classes on subjects from philosophy to astronomy. All courses are free, downloadable, and playable on your Mac or PC via iTunes or on your iOS device.
Check out Yale’s Digital Commons which allows you to search several libraries, museums, and galleries for digital content accessible from anywhere! Again, this is a free resource.
