For many years historians in the United States, even scholars who challenged the relatively benign view of slavery and harsh view of Reconstruction that dominated the academy until at least the 1950s, were reluctant to draw on the testimony of the slaves themselves as found in their personal narratives, including those written before and after the Civil War as well as those collected orally during the WPA Federal Writers Project in the 1930s. Even after the 1950s there was considerable debate over whether these accounts of the "peculiar institution" by former slaves could be considered reliable historical evidence. However, more recently, such firsthand stories have been increasingly employed to put a face on slavery and give a more vivid sense of the human dimension of that crucial, and horrifying, epoch of US history. Two new books, Marcus Rediker's "The Slave Ship" and David W. Blight's "A Slave No More," are both powerful additions to this body of scholarship.
