The International Exhibition of Arts, Manufactures, and Products of the Soil and Mine, unofficially known as the Centennial Exhibition, was held in Philadelphia in 1876 and was attended by more than nine million people. This website presents 1,500 images, including photographs, lithographs, engravings, maps, scrapbooks, and albums, searchable by keyword or subject, on this event.

"Exhibition Facts" provides statistics, a summary of the fair's significance, photographs of buildings erected by foreign nations, and images of sheet music. A timeline traces the fair's lifespan from the 1871 Act of Congress that created its planning commission to the removal of exhibits in December 1876. A bibliography lists more than 130 related works and 17 websites. "Tours" features an interactive map of the fairgrounds. "Centennial Schoolhouse" offers activities, including excerpts from a 17-year-old boy's diary. This website provides revealing images of the event that introduced America "as a new industrial world power."

This bilingual website (English and French) explores the history of the French presence in North America from the early 16th century to the end of the 19th century through more than 360 manuscripts, books, maps, and other documents. Each thematic presentation—"Exploration and Knowledge," "The Colonies," "Franco-Indian Alliances," "Imperial Struggles," and "The French and North America after the Treaty of Paris"—includes a title exhibit and additional exhibits that highlight particular items in the collection. Materials can also be browsed in the collections section.

A timeline (1515–1804) organizes events in French America by explorations, colonization and development, and conflicts and diplomacy, and places them in the context of events in France. Additionally, there are eight descriptive maps that show various Indian groups in contact with the French and the changes in political boundaries in North America from before 1763 to the era of the Louisiana Purchase.

This large, attractive site provides high-quality material on American history for historians and teachers. The collection contains more than 60,000 "rare and important" American historical documents, images, and objects from 1493 to 1998; about 10,000 of these are available online. Authors include George Washington, John Quincy Adams, Harriet Beecher Stowe, Frederick Douglass, and Abraham Lincoln.

Each week an annotated, transcribed document is featured, and an archive contains 80 past featured documents. "Treasures of the Collection" offers 24 highlighted documents and images. Six online exhibits cover topics such as Alexander Hamilton, the Dred Scott decision, Abraham Lincoln, and topics such as freedom and battles. Podcasts with historians address issues such as Presidential history and the Great Depression. Additional resources include links to historical documents, published scholarship, and general history resources on the web.

These printed materials are representative of the public campaigns of the Anti-Saloon League from 1893 to 1933. A six-page history of the League and the Temperance movement and six biographical essays of movement leaders provide context. Facsimiles of 89 fliers produced by the League advocate temperance with arguments that include the effect of alcohol on puppies and German Emperor William II's opinion of drinking. A periodical section reproduces three covers, three sample articles, and one complete 1912 issue of American Patriot, a temperance magazine, and one cover of American Issue.

Other material includes 14 wet and dry maps of the U.S. produced by the League, three temperance anthems, transcriptions of nine anti-alcohol stories, and 12 pro-temperance cartoons. In addition, six entries from the Standard Encyclopedia of the Alcohol Problem, published between 1925 and 1930, offer the Temperance perspective on communion wine, whiskey production, and alcohol use in China.

Significant European migration into the Ohio River Valley occurred from the mid-18th century to the early 19th century and this website presents approximately 15,000 pages of related materials. Resources include books, pamphlets, newspapers, periodicals, journals, letters, legal documents, images, maps, and ledgers. The site includes a special presentation with a 6,500-word essay on contested lands, peoples and migration, empires and politics, Western life and culture, and the construction of a Western past.

Materials address encounters between Europeans and native peoples, the lives of African American slaves, the role of institutions such as churches and schools, the position of women, the thoughts of naturalists and other scientists, and activities of the migrants, including travel, land acquisition, planting, navigation of rivers, and trade. These are valuable resources for studying early American history, cross-cultural encounters, frontier history, and the construction of the nation's past.

Designed to showcase the work of archaeologists and their excavations at Mobile and elsewhere in Alabama, this website offers images and exhibits from several digs. Visitors can "virtually visit" archaeological sites in the town of Old Mobile, capital of the French colony of Louisiane [sic] from 1702 to 1711; the Mississippian Indian city of Bottle Creek (1100–1400); and the Indian fishing site of Dauphin Island Shell Mounds (1100–1550).

Additional sites include the French village of Port Dauphin (1702–1725); the Dog River Plantation site, home to a French-Canadian immigrant family, numerous Indians, and slaves (1720s–1848); and sites in downtown Mobile, including a Spanish colonial house (ca. 1800), an early 19th-century riverfront tavern, and antebellum cotton warehouses.

Artifacts features more than 250 images of pottery shards with accompanying descriptions. Great Links presents 30 additional websites that focus on preservation, archaeology, and Alabama history. The site also includes images and information on seven additional French colonial sites in Nova Scotia, New York, Michigan, Illinois, Mississippi, and Louisiana.

Texts about the Americas produced in Europe from the 15th through the 19th centuries are examined in this well-organized online exhibit. Over 100 images of printed texts, drawings, artwork, and maps from published and unpublished sources are arranged into six thematic categories. Categories are named: "Promotion and Possession," "Viewers and the Viewed," "Print and Native Cultures," "Religion and Print," "New World Lands in Print," and "Colonial Fictions, Colonial Histories."

Five scholarly essays (5,000 to 7,000 words each) contextualize the documents. A bibliography and list of links accompany the presentation. A visually attractive, thoughtfully arranged site that explores connections between colonization and representation.

This massive collection presents more than 550,000 images relevant to both U.S. and world history, from the earliest days of print culture to the present. Resources consist primarily of historical maps, posters, prints and photographs, illuminated manuscript pages, and images drawn from published books.

For browsing, the materials are divided by subject heading, library of origin, and the name of the item's creator and/or publisher. They are also sorted by collection: Arts & Literature; Cities & Building; Culture & Society; History & Geography; Industry & Technology; Nature & Science; and Printing & Graphics. Within these broad headings, images are further subdivided into more specific groupings, for example, Indonesian dance, dress and fashion, Civil War medical care, and New York City apartment buildings. All images can be downloaded and are accompanied by detailed source information, but users will have to turn elsewhere for historical context.

The images in this collection, focusing on the Americas, come from books printed or created in Europe between about 1492 and 1825. Images include woodcuts, copper engravings, and paintings. The database, still being compiled, currently contains 6,685 images and will eventually contain some 7,500 images. Image viewing software is available from the site.

The visitor can browse the entire archive or search by time period, geographical area, keyword, or subject, including indigenous peoples, flora and fauna, artifacts, industry, human activities, geography, maps, city views and plans, and portraits. Some images, such as Ptolemy's map of the world, may be familiar. Others are reproduced for the first time. Navigation requires some practice, but is worth the effort.
