Roy's comment hits the mark.  Fortunately, another good, brief survey is  
available at a much lower price (Roger Backhouse's The Ordinary Business  
of Life) and primary documents are now widely available on the web.  I  
make use of the McMaster University collection and, for 20th century  
economics, JSTOR.  I would guess that my H.E.T. student lay out fewer  
dollars on course materials than they do in virtually any other  
economics class.  Frugality without loss of content is becoming ever  
easier to achieve.
