My first favourite link back in April 2008 when I started this blog was for EconTalk a weekly hour-long discussion that applies the economic way of thinking as to a vast range of subjects. EconTalk is part of a larger website called The Library of Economics and Liberty. I particularly recommend The Concise Encyclopaedia of Economics. The articles, which are free of charge, are written by the most respected economists in their fields, including many Nobel Prize winners. They also have a Guides page, which explains basic economic concepts.
