Academic freedom that's actually free

I've recently gotten into two websites:

http://a.aaaarg.org/login - publishes full versions of many (and I mean many) useful texts for those working in critical theory, cultural theory, linguistics, philosophy, etc.  It includes both primary and secondary texts.

http://www.discoursenotebook.com/blog/ - publishes recorded lectures from important theorists working today. 

Both of these are incredibly useful if you're far, far from a library.

Are there others?
