I wanted to get an idea of what a slave ship might look like, besides the picture offered in the book and discovered these pictures at www.si.umich.edu/CHICO/Schomburg/text/exhibition.html. The site was put together by the Schomburg Center for Research in Black Culture at the New York Public Library. There is lots of information, including a timeline of the African presence in the Americas and even better, a whole list of online resources for exploration.
