I invite you to take a look at my collection of sites on economics - the queen of the social sciences. At the same time I believe that without political analysis, economics can become a gross parody of reality. Therefore I think of economics as political economy with a pinch of public policy analysis.
I also invite you to search the homepages of various universities all over the world . One of my useful academic tools is a large reference desk and bookshelf containing, among other things, an online dictionary, the Bartlett Quotations, and the Encyclopaedia Britannica. Then, there are essential things one must know about the internet, unix, and html, apart from SAS, etc.
