With a focus on business history and its connections to larger cultural, social, and political trends, the Hagley archive presents digital images on a range of topics, including "industrial processes; commercial landscapes; marketing and advertising; transportation facilities and methods; development of information technology; and, the social and cultural aspects of work and leisure." Pictured are bridges, dams, coalmines, and the testing and manufacturing of gunpowder and explosives, nylon, steel, railroads, automobiles, and airplanes. Also included are images of historic buildings, homes, and gardens in Delaware and Pennsylvania.

There are some images of advertisements, packaging, company brochures, trade catalogs, pamphlets, internal documents, letters, and other ephemera from various industrial enterprises. It includes, for example—under "nylon"—not only shots of machinery, product samples and images of the stages of melting and forming polymers, but also such treasures as ads and publicity shots of women modeling nylon stockings and swimsuits (including "Miss Chemistry" at the 1939 New York World's Fair), and news photos of the riotous early sales of nylon stockings.

Other topics include the early development and use of computers by Univac, IBM, and Remington Rand, aerial photos of the Mid-Atlantic seaboard; automobiles; Lukens Steel Company; ship building; and coal mining.

Designed as both an archive and an online exhibit, this site features 3,457 hand-drawn township maps of Illinois. When the government began surveying in 1803 what would later become Illinois, they divided the land into squares six by six miles (36 square miles) called townships. This site includes a 1,000-word introductory history describing the surveying process and introducing the methods and tools of surveyors. Also included here are the maps, available to researchers and the public. A 1,000-word narrative outlines the role of the United States Surveyor General, and traces the custody of these records through the years.

Visitors use a map of Illinois to locate the region and county of the plat they wish to view, and can pan left and right or zoom in and out. A legend helps users decipher early 19th-century symbols. In addition, the site links to an Illinois state website (Illinois Public Domain Land Tract Sales), where researchers can search for the first owners of plats. This site is a great place to view original, early-19th-century maps of Illinois.

Designed to document approximately 180 ghost towns in Colorado, New Mexico, Arizona, Montana, Nevada, California, Idaho, and Utah, this site features more than 1,700 photographs taken in the year 2000 of ghost towns across the west. About half the photographs include captions, while the other half do not. The site features a 750-word essay on the history of the Gold Rush, as well as an interactive map of the west that allows visitors to highlight a region, then an area, then a ghost town, to view photographs of the selected town.

Featuring primarily maps, texts, and images, this gateway site is designed to be a resource for those interested in the history of the greater Cleveland area. The site includes approximately 35 journal articles (from journals such as the Saturday Evening Post) on the history of Cleveland, its newspapers, its railroads and industries, and a few prominent citizens; 36 digitized books; seven manuscript collections (three merely describe the contents of the collection, while four offer digitized resources); an audio file and a video file; two cartoon collections; and nine photograph collections, containing about 600 photographs. Although many of the collections are located on outside websites, visitors can access the collections by subject, date, geographic location, or format.

For educators, the site includes 20 lesson plans, under such categories as American Heritage and Democratic Process. The classroom activities are well-conceived; they feature problem solving and critical thinking exercises like the Mystery Photo Album, in which students attempt to figure out where in the Cleveland area historical photographs were taken, and By the Neck Until Dead, an e-book that details the history of Cuyahoga County, OH, hangings. The site also maintains a list of local history websites.

Provides nearly 1,500 images of 280 architecturally significant American buildings from the colonial era to the present, compiled by Professor Jeffery Howe for classroom use. Images are arranged according to period, location, architect, building type, and style. The site offers examples of houses, churches, public buildings, commercial buildings, and skyscrapers. It includes images from three World's Fairs, as well as sections on urban planning and comparative materials. Professor Howe also has digitized images and text from two mid-19th century books on design and ornament.

In conjunction with the Russian State Library in Moscow, the National Library of Russia in St. Petersburg, and the Rasmuson Library of the University of Alaska in Fairbanks, the Library of Congress has digitized more than 2,500 items, comprising approximately 70,000 images, and provided transcriptions and commentaries in English and Russian to offer a comparative history of American and Russian expansion through frontier territories in each nation's continent. The site presents an overview of expansion into Siberia and the American West in six sections: Exploration, Colonization, Development, Alaska, Frontiers and National Identity, and Mutual Perceptions. Each section contains from two to 11 modules that call attention to similarities and differences between the two histories with regard to subjects such as migration—forced and otherwise, missionaries, religious flight, mining, railroads, agriculture, cities, popular culture, and tourism, and even compares Cossacks with cowboys.
