Like having a child, a book is labor intensive and, if it survives infancy, it takes on a life of its own. People tell you it looks like you, which is no compliment. You can't disown it when it gets into trouble. Admittedly, Agriculture in An Unstable Economy is a good name to have; it got through six printings and, for all I know, because of its name. Now that it looks as old as its parent, I am asked to talk about it with no assurance that what gets said can be erased.
