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 Territorial Kansas collections convey the growing divisions in Kansas and the nation over the expansion of slavery, federalism, nationalism, industrialization, and changing political coalitions in Congress. Materials include government documents, diaries, letters, photographs, maps, newspapers, rare secondary sources, historical artifacts, and images of historic sites.

Visitors will find essays on territorial politics, the rights of women and African Americans, military organizations, and free state and pro-slavery organizations. "Personalities" lists 32 individuals, including John Calhoun, and the final section presents both anti-slavery and pro-slavery perspectives of the national debate about Kansas. The site also includes a timeline with links and an annotated bibliography.

The Naval History and Heritage Command collects, preserves, and presents the history of the U.S. Navy in physical locations throughout the U.S. and online. Teachers will be most interested in "Resources & Research," a rich collection of primary and secondary sources related to naval history, including photographs, paintings, documents, oral histories, historical overviews, chronologies, and bibliographies. Teachers may want to start with "Photograpy," "Web Exhibits," or "Commemorations," some of the richer and more navigable sections.

"Commemorations" features collections of resources related to specific events, including the bicentennial of the War of 1812, the sesquicentennial of the Civil War, the Battle of Midway, and the 1941 attack on Pearl Harbor.

Hundreds of thousands of documents spanning four centuries of American history are available in this large archive. Broadsides, ephemera, pamphlets, and booklets are available from 1639 to 1900. More than 1,300 newspaper titles, representing all 50 states, range in date from 1690 to 1922.
