I've had this book for a little over a year now, and I *finally* had the chance to read it last fall. Martha S. Jones has authored a really wonderful monograph about free African Americans in antebellum, popular constitutionalism, and legal consciousness. This is a must read for anyone doing 19th century U.S. history, both transnational and domestic. 'Birthright Citizens' is an excellent example of how studies in legal history can attend to law as much as they attend to cultural life.
