*Knowledge and Coordination: A Liberal Interpretation*

The author is Daniel Klein and you can buy it here.  My blurb reads:

The best book on Smithian economics, or for that matter Austrian economics, in many years.

Here is a thirty-minute presentation of some themes from the book.  Here is an associated podcast with Dan and Russ Roberts.  Here is the syllabus for Dan's class on economics and philosophy (pdf); here is the syllabus for his class on Adam Smith (pdf).
