M. Scott Heerman's Sources and U. S. Citizenship in the Antebellum United States: A View from Abroad is available as a "first look" in Law and History Review:
This article republishes a series of documents concerning citizenship rights for African Americans who were abroad. Twice during the 1850s the U.S. Secretary of State (William L. Marcy) issued instructions to consuls where he spelled out the relationship between race and citizenship for individuals who were beyond the borders of the United States. Because citizenship was not clearly defined the antebellum period, either in law or practice, the Secretary's guidance offers an important set of documents that scholars from a variety of fields can incorporate into their scholarship and teaching.
