For scholars who consult the US Census in their research, historian Schor's outstanding book is invaluable....The research is impeccable, especially Schor's use of congressional archives to determine political thinking over a period of almost a century and a half. Most revealing is the author's discussion of the division between the North and South concerning blacks during slavery and Reconstruction....Essential.
