Seems like I am always referencing Charles Murray and Real Education. I remember reading a review of Real Education that complained that Murray could easily have provided a website that had all his hyperlinked references in it, but did not. So, I started a page with just those references on it. I put it on the right sidebar under Education. I often find that I need them, so this is entirely self-interested. I'm up through Chapter 2 now, more to come.
