Agriculture in the United States has changed dramatically since the 1940s. Changing Works: Visions of a Lost Agriculture by Douglas Harper (University of Chicago Press, $35, £22.50), documents the shift from small units and a cooperative approach to the industrialized, mass-production systems seen today. Drawing on a host of photographs from the 1940s, the book also illustrates the unstoppable rise of mechanization and automation in the industry.
