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. The website is divided into five sections: Territorial Politics and Government; Border Warfare; Immigration and Early Settlement; Personalities; and National Debate about Kansas. Each is searchable by keyword, author, and county. Topical sections are subdivided into relevant themes and include an introductory essay. 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.

With full-text versions of seven books and essays in addition to five 19th- and early 20th-century biographies, this website presents the life and works of Thomas Paine (1737–1809). Materials include Common Sense, The Rights of Man, The Age of Reason, The Crisis Papers, "African Slavery in America," "Agrarian Justice," and "An Occasional Letter on the Female Sex." These texts are reproduced from The Complete Writings of Thomas Paine, a 1945 publication edited and annotated by historian Philip S. Foner. The site also includes Foner's section introductions and his "Chronological Table of Thomas Paine's Writings." Unfortunately, the site also includes hundreds of broken links to additional essays and letters by Paine. The biographies presented provide works published from 1819 to 1925. The site also reprints Thomas Edison's 1925 essay, "The Philosophy of Thomas Paine," in which he attempted to reawaken interest in Paine.

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. "Photography" features an online library of selected images on subjects including recruiting posters, albums and scrapbooks, women in the U.S. Navy, aircraft, naval insignia, individual ships, and more. "Web Exhibits" gathers together more than 20 curated collections of resources on topics from the Civil War to Japan/U.S. Navy relations; resources vary by exhibit but include documents, photographs, videos, related articles, oral histories, and links to off-site resources. "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. Teachers may also find unique primary sources in "Art." The Naval Art Gallery offers more than 25 galleries including "Women in Uniform" and "The Invasion of Normandy." Additionally, the "Archives" section provides downloadable Commander Naval Forces Vietnam (COMNAVFORV) monthly summaries from 1966 to 1973 and links to other archives holding material on the U.S. Navy. "Navy Department Library" makes available naval documents from 1775 to the present day (note that the documents are presented chronologically by topic, with no distinction between primary and secondary sources). "Diversity" directs visitors to collections on women, African Americans, Asian and Pacific Islander Americans, Hispanic Americans, and Native Americans in the U.S. Navy. "Videos" indexes more than 90 video clips, some primary sources and some secondary. "Ships Histories" provides brief histories of specific ships, indexed by name, and "Aviation" provides data on different types of aircraft and aircraft carriers. "Bios" features more than 100 essays with images on naval figures. Teachers will need patience to navigate the site and uncover the primary sources available.

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. U.S. Senate and House of Representatives reports, journals, and other documents are available from 1817 to 1980. Legislative and executive documents from the Early Republic are also included. The entire body of documents is keyword searchable, and, in addition, each collection can be searched and browsed individually. These documents shed light on many aspects of American social, political, economic, and cultural history, and can provide a valuable window into the daily lives of early Atlantic peoples. The collection of broadsides and ephemera is especially useful for exploring the history of printing in the United States, as all titles can be browsed by bookseller, printer, or publisher.

This anthropological exhibit displays, explains, and interprets the Lakota pictorial histories known as winter counts. Featuring a searchable database of winter count images, a documentary about Lakota history and culture, and video interviews with Lakota people, website visitors can view images from 10 winter counts and examine their symbols in detail by year with curator comments. Visitors are also able to examine the various symbols used by the winter count keepers to represent plants and animals, ceremonies, health, trade goods, places, people, the U.S. government, and the sky. "Who Are the Lakota" offers a historical overview of Lakota history in 10 segments that include the Lakota and the Sioux people, Lakota origins, westward migration, horse-centered culture on the northern Great Plains, important conflicts and treaties, confinement to the Great Sioux Reservation, and subsequent land cessions.

This scanned and partially searchable version of the 15-volume Public Records of the Colony of Connecticut, from April 1636 to October 1776, was originally published between 1850 and 1890. Users can search documents by date, volume, and page number. Each of the 15 volumes, covering consecutive time periods, includes alphabetical, hyperlinked subject terms for browsing. The site also provides access by type of material: charters, documents, inventories, laws, letters, and court proceedings. Keyword searching may be available in the future, but even without this option, the site offers a wealth of accessible material on politics, legal matters, Indian affairs, military actions, social concerns, agriculture, religion, and other aspects of early Connecticut history.

These varied collections document the history of Los Angeles and southern California. "Digital Archives" offer more than 126,000 photographs, maps, manuscripts, texts, and sound recordings in addition to exhibits.

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.
