Of all the lists of "Best Business Books of 2009," our favorite is that of Marketplace host Kai Ryssdal.  And we have a few reasons.  First, it includes some of the top books that addressed the changing nature of the markets and the financial system--namely Andrew Ross Sorkin's Too Big to Fail, and Ken Rogoff's This Time is Different.  Second, it includes books from some of the top online econ and finance writers, like Barry Ritholtz of The Big Picture, and Justin Fox, who blogs at The Curious Capitalist.  Third, it has some refreshing surprises, like Chemical Cowboys--a look at the fall of the ecstasy empire by Lisa Sweetingham.  But the main reason this is the Best of the Best of Business Books for 2009?  It is a list of books AND a collection of interviews with the authors of those books.  Take a look and a listen by clicking here.
