I believe Mike Veach tipped us some time ago that this was in the works.
The University of Kentucky Press has decided to republish Henry Crowgey's Kentucky Bourbon: The Early Years of Whiskeymaking.
Originally published in 1971, this is one of the few serious scholarly works ever done on the subject, and is a very thorough and credible account of the industry's development in the late 18th and early 19th centuries. The release is scheduled for February, 2008. Amazon is accepting pre-release orders. (That's the link.)

, you will put a few pennies in my pocket, but the cost to you is the same.
