This is one of the richest collections of anti-slavery and Civil War materials in the world. Reverend Samuel J. May, an American abolitionist, donated his collection of anti-slavery materials to the Cornell Library in 1870. Following May's lead, other abolitionists in the U.S. and Great Britain contributed materials. The collection now consists of more than 10,000 pamphlets, leaflets, broadsides, local anti-slavery society newsletters, sermons, essays, and arguments for and against slavery. Materials date from 1704 to 1942 and cover slavery in the United States and the West Indies, the slave trade, and emancipation. More than 300,000 pages are available for full-text searching. Accompanying the documents are eight links to other collections.

More than 100 published materials on legal aspects of slavery are available on this website. These include 8,700 pages of court decisions and arguments, reports, proceedings, journals, and a letter. Most of the pamphlets and books pertain to American cases in the 19th century. Additional documents address the slave trade, slave codes, the Fugitive Slave Law, and slave insurrections as well as presenting courtroom proceedings from famous trials such as the 18th-century Somerset v. Stewart case in England, the Amistad case, the Denmark Vesey conspiracy trial, and trials of noted abolitionists John Brown and William Lloyd Garrison. A special presentation discusses the slave code in the District of Columbia. Searchable by keyword, subject, author, and title, this site is valuable for studying legal history, African American history, and 19th-century American history.

Focusing on the experiences of Africans and African Americans in New York City, this collection presents nine galleries that explore various themes and time periods in the history of slavery. These include the Atlantic slave trade; slavery in Dutch New York; the growth of slavery in British Colonial New York; freedom for blacks during the Revolutionary War; the Gradual Emancipation Act of 1799; free blacks in public life; Emancipation Day (July 4, 1827), and the history of scholarship on slavery in New York City. Each gallery has three panels: a gallery overview, a main thematic presentation, and one focusing on people, places, and documents. Of special interest are two interactive maps with timelines in the Dutch New York gallery and the Revolutionary War gallery; a picture gallery on the portrayal of blacks in New York City's public life; and profiles of nine African Americans who lived in New York City during the early republic.

These more than 200 documents explore cultural connections between the experiences of African Americans and Irish immigrants in America. Materials relate to individual leaders, historical events, economic, political, and social factors, and cultural achievements. A section entitled "Making Connections" offers 15 questions about historical events and people that represent the intertwined histories of Africans and Irish in America.

Other topics include the end of English participation in the slave trade, the emergence of the nativist Know-Nothing Party in the 1850s, and Ku Klux Klan activities against Catholics and blacks after the Civil War. A section on "Acceptance" explores perceptions of individual and group identities and four timelines focus on displacement, oppression, discrimination, and acceptance in America. "Voices" provides a sample of 13 public statements and interviews on ethnicity and race from ordinary modern Americans. The site also provides a bibliography; an essay by writer James McGowan, a black American with an Irish paternal grandfather; and links to related websites.

This collection of more than 1,230 images depicts the enslavement of Africans, the Atlantic Slave Trade, and slave life in the New World. Images are arranged in 18 categories, including pre-Colonial Africa, capture of slaves, maps, slave ships, plantation scenes, physical punishment, music, free people of color, family life, religion, marketing, and emancipation.

Many of the images are from 17th- and 18th-century books and travel accounts, but some are taken from sketches within slave narratives, Harper's Weekly, and Monthly Magazine. Reference information and brief comments, often an excerpt from original captions, accompany each image. Although there is no interpretation or discussion of historical relevance, these images are valuable for learning about representations of slavery in American slave societies, especially in the Caribbean and Latin America.
