Economic Principals update

Long ago, I wrote a review for Reason of Economic Principals: Masters and Mavericks of Modern Economics, by David Warsh. This was so long ago in fact (1993) that Reason's online archives don't go back that far, though my review can be found here. In the interest of examining the diversity of ways for trying to generate income through writing for the Web, I note that Warsh now runs his former newspaper column as a website that's free but that gives an early edition and a quarterly newsletter to buyers of a $50 subscription.
