The highlight of the site is its Online Exhibitions section. There are currently 64 exhibits available. These include Separate is Not Equal, celebrating the 50 year anniversary of the Brown v. Board of Education decision (including audio and video files); Bon Appetit, documenting chef Julia Child's kitchen and career (including panoramic views and virtual examination of Childs's kitchen tools); and West Point, marking 200 years of military academy training.

Parents and teachers may appreciate the Kids area with hands-on history and science. Less useful for research, this site would be most useful as a virtual visit to the Museum.

An engaging exhibit geared especially to schoolchildren, this site provides images, texts, and activities to explore the history and operation of the American presidency. Organized into four sections, the exhibit displays more than 375 images of documents, paintings, photographs, buttons, posters, paraphernalia, and objects along with short texts (50–200 words in length) explaining their significance. The Foundations pertains to the prehistory of the presidency, how the Framers defined responsibilities of the office, and the basic work that the office requires. The Campaign Trail covers the election process. Life and Death in the White House looks at the domestic world of the president, life after leaving office, and assassinations. Communicating the Presidency deals with the press, the entertainment industry, and advertising.

Most impressive are the many suggested activities, lesson plans, and games designed for children of varying ages. A Teacher's Manual contains five lesson plans each for grades 4–6, 7–9, and 10–12. In addition, there are activities for younger children, including analyzing letters between children and five presidents and creating a new official seal. Provides a timeline, bibliography of 88 titles arranged according to age group and exhibit section, and annotated list of 46 links to other sites. Very useful for classroom history and civics courses.

This exhibit tells the story of "the flag that inspired the National Anthem" through more than 50 images and short texts (50–200 words) explaining their significance. Also presents images from Smithsonian collections to illustrate sections on expressing patriotism, fostering national memory, and how "common cultural symbols, such as the American flag, patriotic songs, presidential images, and monuments, serve to coalesce a common identity among Americans." Elucidates challenges the Smithsonian faces to preserve the flag that flew over Fort McHenry during the Battle of Baltimore in 1814 and inspired Francis Scott Key's poem.

Provides a teacher's manual in three sections for grades K–2, 3–5, and 6–8 and suggestions for using the site in the classroom. Includes a 10-title reading list, links to 14 related sites, and games designed to stimulate students to use primary sources to investigate "mysteries surrounding this famous flag." A well-conceived site, though modest in size, that will prove useful for K–8 classes.

Offers approximately 50,000 images of 6,500 items from the papers of 19th-century American scientist and painter Samuel F. B. Morse (1791–1872), inventor of the electromagnetic telegraph. In addition to science and art-related papers, the materials in the collection document Morse's interest in photography and religion, as well as his involvement with the American nativist movement. Includes correspondence, diaries, notebooks, scrapbooks, newspaper clippings, books, pamphlets, broadsides, maps, drawings, and other materials, primarily produced during between 1807 and 1872.

The site provides a timeline supplemented with 15 documents; a family tree; two essays of approximately 1,000 words each (entitled "The Invention of the Telegraph" and "The Lesser-Known Morse: Artist, Politician, Photographer"); a bibliography of 22 titles; and links to 16 additional sites.

Searching capabilities leave much to be desired. Keyword searching applies only to titles assigned to documents by the Library of Congress. Thus even though the finding aid lists "Nativism" as a subject, a keyword search turns up nothing. The site unfortunately is of limited use because of this shortcoming.

This collection of more than 160 texts, maps, photographs, and sketches is focused on the people, themes, and organizations important to Reston's history as a planned community. Textual materials include deeds, certificates, promotional brochures, studies, reports, and correspondence. Maps include Reston's Master Plan, major road systems, educational facilities, and recreational areas. Photographs include Lake Anne, various physical structures, and people significant to Reston's history. Sketches are mostly of building and community plans. Subject areas include health care, education, public services, parks, recreation, transportation, and population.

The collection can be browsed by title, subject, people, or organization and it can also be searched by subject, personal name, corporate name, or title. This is a website of interest to those researching the history of Reston or of planned communities.

This exhibition commemorates the 50th anniversary of the pivotal 1954 Brown v. Board of Education of Topeka, Kansas case. It offers 116 images, including book covers, letters, political cartoons, and photographs. Exhibition Overview is a 300-word introduction to the exhibit and its significance.

The website is divided into three sections: A Century of Racial Segregation, Brown v. Board of Education, and The Aftermath, all of which consist of links to documents, detailed paragraphs on selected documents, and events related to that section. "Discover" buttons are dispersed throughout these exhibit sections; and, when clicked, reveal more information and answer a particular question, such as "What is 'separate but equal?'"

The Exhibition Checklist includes links to all images used on the site. The site is an ideal resource for students interested in the historical developments that led to the Brown v. Board decision.

A web-based reference work, this site provides authoritative and accurate information on people, places, institutions, and events for many aspects of Georgia's life, history, and culture. The encyclopedia offers close to 2,000 articles and 8,000 multimedia files on a range of categories, including art, business, education, politics, history, religion, and sports with specific articles on topics such as architecture: building types (houses, public schools, roadside, and vernacular), military bases, folklife projects, and gymnastics at the University of Georgia.

Within the essays, there are links to related essays and external websites. There are also video and audio clips as well as images and some maps. New material is added regularly and the site also offers basic stats on the state, features and destinations, and galleries.

Designed to explore the historical similarities and contrasts, ethnic diversity, and interactions between Brazil and the United States, this site contains almost 1,000 images from the rare book, manuscript, map, print, and photographic collections of the Library of Congress and the National Library of Brazil.

The site includes letters (including letters from Thomas Jefferson concerning the independence of Brazil), illustrations, 18th-century maps, and other textual items, including poetry.

The sources are available in five categories: "Historical Foundations," "Ethnic Diversity," "Culture and Literature," "Mutual Impressions," and "Biodiversity" (right now, only the Historical Foundations section is completed). The site is viewable in both English and Portuguese, and is appropriate for high school and college students, as well as teachers and researchers.

This site introduces Emma Goldman—an immigrant, an advocate of free love, a promoter of birth control, and an anarchist. The designers have done a splendid job in tying the many facets of Goldman's public life together into one set of interrelated narratives. An "Introduction" is divided into 13 thematically coherent sections, such as Early Years, Anarchism, Use of Violence, and Deportation. Each runs approximately 500 words. A Timeline is useful for placing Goldman into historical and cultural context.

There are several dozen artifacts, including the full text of two books, six cartoons, four historical documents, an analytical essay, two personal letters, 12 news clippings, and 16 photographs. The information is well documented, and includes a detailed bibliography.

The care that the producers took in explaining potentially confusing or problematic terms (like feminism and suffrage) makes the site particularly appropriate for high school and undergraduate students. Although not a comprehensive archive, this site nonetheless provides an informative introduction to Goldman and her role in American history.

Designed to commemorate the 400th anniversary of the French landing in North America, this site is a collection of primary sources related to the French presence in what would later become Canada, the Great Lakes region, and Louisiana. Exhibition features 350 primary sources, including engravings, portraits, other artwork, as well as documents. They are organized by theme and are easy to find and view.

Database includes a database of more than 6,500 documents, including correspondence, reports, and maps. A special viewer allows visitors to zoom in and out of documents, making close viewing possible.

The collection is searchable by date, author, subject, or keyword. Visitors should keep in mind that although the site is written in English and French, the documents are written exclusively in French. The wealth of primary sources makes this a valuable resource for researchers, but language may prove a barrier for students and teachers.
