Historian and New York Law School Professor Annette Gordon-Reed has recently published an acclaimed new book, The Hemingses of Monticello: An American Family (W.W. Norton, 2008), which has been nominated for the National Book Award and favorably reviewed in the New York Times.
As a complementary work, B. Bernetiae Reed has compiled and self-published a fascinating look at the 619 slaves who lived at Monticello, replete with facsimiles of many original documents.
Reed's website provides information on the two volume work; our copy is in the stacks in Green Library.
