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.

The Detroit Publishing Company mass produced photographic images—especially color postcards, prints, and albums—for the American market from the late 1890s to 1924. This collection offers more than 25,000 glass negatives and transparencies and about 300 color photolithographs from this company. It also includes images taken prior to the company's formation by landscape photographer William Henry Jackson, who became the company's president in 1898. Jackson's work documenting western sites influenced the conservation movement. Although many images were taken in eastern locations, other areas of the U.S., the Americas, and Europe are represented. The collection specializes in views of buildings, streets, colleges, universities, natural landmarks, and resorts, as well as copies of paintings. Nearly 300 photographs were taken in Cuba during the Spanish-American War. About 900 Mammoth Plate Photographs include views of Hopi peoples and their crafts and landscapes along several railroad lines in the 1880s and 1890s.

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.

The National Archives and Records Administration holds more than 10 billion items addressing the social, economic, political, and cultural history of the U.S. This interactive website makes more than 1,200 of those items available, including official documents, personal accounts, images, maps, and ephemera. Browsing is easy from the main page which presents a rotating cast of eight archival items—from an early engraving of the Declaration of Independence, to a top secret document on dropping the atomic bomb, to an image of Navajo code talkers.

More than 550 tags and a keyword search render the items accessible to those interested in specific topics, such as "Abraham Lincoln" (20 items), NASA (19 items), and "Yellowstone National Park" (three items). Each item is accompanied by a brief annotation providing historical context and related tags, further facilitating browsing. All items can be zoomed for highly detailed viewing and rendered printer-friendly for classrooms without computer access.

The website also provides a variety of tools allowing users to collect and manipulate items. "Create" presents the opportunity to make individualized posters and movies out of any item or group of items from the website. After a free login, users can save and email these creations for future use.
