A monumental cartographic history of the African slave trade, updated and expanded in a new edition   In the first edition of Atlas of the Transatlantic Slave Trade, two leading historians explored details of the 350-year history of African slave traffic to the New World. They showed, with nearly 200 original maps, where the captives came from, how long the journeys lasted, how many died on the voyages, and what the ports and destinations were. They also presented details about the trade itself, including the economics.   In this groundbreaking revised edition, 25 new maps locate the major language groups involved in the traffic and show the movement of Africans from the interior of the continent to the Americas, as well as from one part of the Americas to another. Accompanying the maps, as in the first edition, are revealing illustrations and contemporary literary selections, including poems, letters, and diary entries.   With up-to-date information drawn from the database Slave Voyages (www.slavevoyages.org), with its records of more than 36,000 voyages, the atlas provides the fullest possible picture of the extent and inhumanity of one of the largest forced migrations in history.
