This site, designed as a companion to the PBS film, is quite useful in its own right. Among other themes, the site explores the role of photography in American history, beginning with the role of photography as a relative newcomer to art.

In addition, the site examines the ways in which photography has impacted warfare, politics, and advertising. Moreover, the site raises important questions about whether photographs portray a subjective reality and whether photographers influence viewers' perceptions through cropping or digital manipulation. An Image Lab allows visitors to explore the ways that camera perspective and cropping can change the meaning of a photograph. Visitors can use the tool to manipulate stock photographs and view the results.

A Teacher's Guide provides five lesson plans, asking students to decide whether censorship is a worthwhile practice and to consider ethical issues related to altering photographs.

Not a particularly deep collection of images, this site's strength is the way it teaches how to evaluate and understand photographs, especially historical photographs.

Charts the institutional history of George Mason University from its beginnings in 1949–50 as an adult education extension of the University of Virginia located in northern Virginia, through its formal separation from UVA in 1960, to its present-day existence as a multi-campus university.

Offers more than 30 documents and nearly 50 photographs related to the history, a 400-word biography of George Mason, an annotated chronology, and a current 108-page fact book. Of interest to those studying the history of education and Virginia history.

This site is a collaborative effort between the Connecticut Historical Society, the Thomas H. Dodd Research Center at the University of Connecticut, and the Mystic Seaport Museum, funded by a National Leadership Grant from the Institute of Museum and Library Services. It offers approximately 14,000 images depicting Connecticut's history from the beginning of the 19th century to the middle of the 20th century.

The images are divided into categories: "Artifacts," "Manuscripts and Documents," Maps, Charts, and Bird's-eye Views," "Newspapers and Magazines," "Photographs, Prints, and Drawings," "Posters/Broadsides," and "Sound Recordings and Transcripts." Each image includes notes on the creator, date, and place created, medium, repository information, and a brief (40-word) description of the subject. Visitors can search the site by keyword, subject, creator, title, and date.

The site also includes four sample lesson plans for middle school classes comparing and contrasting two Connecticut families and the roles of men and women through exercises interpreting the site's images, a list of ideas for future topics, and themes for secondary-level classrooms. This site is ideal for teachers and students interested in the history of Connecticut and its communities.

This collection of materials addresses the Moravian community of Bethlehem, PA, from its founding in 1741 to 1844, when the community first opened to non-Moravians. Most documents are available in three formats: facsimile of original in German type, transcription, and translation into English. All documents may be read in English.

A 650-word essay introduces visitors to Bethlehem history. The community kept a diary that visitors may read for the years 1742 to 1745. The Journal of the Commission of the Brethren of Bethlehem, from 1752 to 1760, allows further access to the inner workings of the community. The death register currently lists 400-word obituaries for five women and six men. Birth and marriage registers are to be added to the site.

Moravians of this era read memoirs (2,000–3,000 words) at the funerals of community members, sometimes incorporating autobiographical writing. Visitors may read 34 of these memoirs.

The records of the community also include four maps, a survey, and the ledgers of the town finances from 1747 to 1765. Inventories of four shops may also be examined.

Other material includes a 32-page 1876 historical sketch of the Bethlehem Seminary for Young Ladies, a 19-page scholarly essay on the Moravian approach to business, and a 1762 discussion of how to finance the Single Sisters' Choir. Visitors may search the site by subject. The site will be very interesting for research in colonial history and the history of religion in America.

A product of the American Studies program at the University of Virginia, this site attempts to "construct a virtual American ca. 1831-32"—the period that Frenchman Alexis de Tocqueville visited the United States—in order to illuminate Democracy in America, his classic examination of political and social life in the young nation. The book is still regarded by some scholars as the greatest ever written about the United States.

The site presents a hypertext version of the book—one translation among many—accompanied by 13 projects on topics such as Tocqueville's sources and the 1840 Census, race relations, fashion, religion, women, art, navigation, and humor. These projects are uneven in quality, though a few—such as the navigation projects—provide useful primary material and worthwhile background texts. Overall, the character of the site seems somewhat ad hoc.

[SUBSCRIPTION REQUIRED FOR FULL ACCESS] Offers abstracts of Encyclopedia Britannica entries to all visitors and full-text articles to "premium service" subscribers. Users can browse alphabetically and by subject, or enter search terms for links to relevant journal articles and sites.

The "BritannicaSchool" subscription service offers K-12 curriculum activities designed to conform with state and national standards. With a wealth of information provided in abstract form, the site is of great valuable even to non-subscribers.

One "showcase" within a multi-part exhibit that presents Soviet archival documents, this site offers three items related to Cold War politics and ideology: a 1945 telegram from Stalin to Harry Truman; a 1971 document from the Communist party's Central Committee, "Additional Measures To Expose Imperialist Policies"; and a 1962 telegram from Khrushchev to John Kennedy protesting American policy in Cuba.

The documents, available as both untranslated images and translated texts, are accompanied by a useful introduction of 1,036 words.

Visitors should consider using the site's "guided tour," which incorporates these materials within the larger exhibit.

Dedicated to "enhancing knowledge about the built environment of the Chicago region," this site hopes to offer a comprehensive "system for indexing, storing, retrieving, comparing, and analyzing images, maps, data, literature, and other geographically-based materials" on Chicago.

Contains an array of historical and recent maps, photographs, and illustrations, plus textual information about Chicago's history and architecture.

Includes approximately 600 aerial photographs taken in 1996 by Alex S. MacLean; 83 photographs by C. William Brubaker; 14 by Robert Thall; multiple images of 55 buildings and historic sites; four Works Progress Administration land use maps; more than 30 images dealing with the Chicago Fire of 1871; 20 photographs by William Henry Jackson and Charles Dudley Arnold of the 1893 World's Columbian Exposition; 22 Rand McNally "Bird's Eye Views" from 1893; and numerous additional maps and images.

An animated map shows the city's expansion and the development of neighborhood communities from 1850 to 1990.

Presently, the site focuses on four Chicago areas: the "Loop," Lawndale, Armour Square, and Bridgeport. Though not updated since 1999, the site contains useful materials documenting Chicago's development.

This site provides documents, essays, and questions about the events leading up to the Confederate attack on Fort Sumter in 1861 and places the events within a broader context of secession and southern independence.

There are nine chronological sections and students must make decisions at five "critical junctures," soliciting advice from official and unofficial advisors. Students can compare their choices with Lincoln's, and a commentary section challenges students to explore multiple interpretations of events. "Hotwords" provide additional information on topics throughout the simulation.

Provides over 200 references in the bibliographic section.

Well-designed activity for helping students at the high school and college level explore the issues surrounding the Civil War.
