In Motion: The African-American Migration Experience

In Motion: The African-American Migration Experience is a new resource from the Schomburg Center at the New York Public Library. From the site's home page:

Of the thirteen defining migrations that formed and transformed African America, only the transatlantic slave trade and the domestic slave trades were coerced, the eleven others were voluntary movements of resourceful and creative men and women, risk-takers in an exploitative and hostile environment. Their survival skills, efficient networks, and dynamic culture enabled them to thrive and spread, and to be at the very core of the settlement and development of the Americas. Their hopeful journeys changed not only their world and the fabric of the African Diaspora but also the Western Hemisphere.

Very highly recommended.
