The companion site to the PBS series, this website has a list of primary source material and overviews of different periods - from the early colonial period to antebellum slavery. Very useful.
This PBS site is a useful starting point containing chronologies, maps and other source material for those wishing to explore the nature and impact of slavery in the United States.
Over 1,000 images relating to the slave trade and slavery across the Americas.
This site offers a timeline on the history of slavery compiled by an activist for preservation of African-American history sites in Washington, D.C. The timeline was compiled from archive, library, and Internet sources to provide background information for research on the history of slavery and racism in the United States. The timeline is divided into three chronological sections: 1619-1789, 1790-1829, and 1830 to "the end". For each year listed in the timeline there is an essay (150-750 words) describing major events and incorporating links to related sites and suggested readings. Approximately 20 graphs, tables, and images are also incorporated into the timeline. Though the site has no primary documents, it is a good start for the study of the history of slavery and Africans in America.
