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.

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.

This annotated collection of more than 30 letters addresses the personal and political costs of war. Letters cover conflicts from the Revolutionary War to the current war in Iraq and are divided thematically into five sections: "Enlisting," "Comforts of Home," "Love," "Combat," and "The End of the War." Letters come from well-known military figures, such as Douglas MacArthur and Robert E. Lee, as well as ordinary veterans, such as Peter Kiterage, one of the 5,000 African Americans who fought in the Revolutionary War. The thematic organization allows users to chart changes and continuities over 200 years of American history. Each letter is read aloud so students can listen as well as read. In addition, a "magic lens" feature provides transcriptions over the original handwriting to help students decode the letters.

Historic American Sheet Music includes more than 3,000 pieces published between 1850 and 1920. Documents from the Women's Liberation Movement offers more than 40 documents from 1969 to 1974. William Gedney Photographs and Writings provides close to 5,000 prints, work prints, and contact sheets from the 1950s to the 1980s.

More than 1,000 photographs depict Civil War military personnel, preparations for battle, and the aftermath of battles in the main eastern theater and in the west in this collection. Photographs also include Federal Navy and Atlantic seaborne expeditions against the Confederacy, Confederate and Union officers and enlisted soldiers, and Washington, DC during the war. Most images were created under the supervision of photographer Mathew B. Brady. Additional photographs were taken by Alexander Gardner after leaving Brady's employment to start his own business.

The presentation "Timeline of the Civil War" places images in historical context. "Does the Camera Ever Lie" demonstrates the constructed nature of images, showing that photographers sometimes rearranged elements of their images to achieve a particular effect. This website is useful for studying 19th-century American photography and Civil War history.

This massive, searchable archive compares two Shenandoah Valley counties during the Civil War period—Augusta County, VA and Franklin County, PA. These two counties were divided by 200 miles and the institution of slavery. Thousands of pages of maps, images, letters, diaries, and newspapers, in addition to church, agricultural, military, and public records provide data, experiences, and perspectives from the eve of the war until its aftermath. The site furnishes timelines, bibliographies, and other materials intended to foster research into the Civil War and the lives of those affected by it. The website includes a section on John Brown and one entitled "Memory of the War," presenting postwar writings on battles, the lives of soldiers, reunions, obituaries and tributes, and politics.
