Visitors may browse these "website archives" to access the transcripts of 60 American Experience documentaries broadcast on PBS. In addition, the site offers transcribed interviews with the filmmakers, a timeline of events of each the of the film topic's era, and teaching guides.

Documentaries cover a wide range of topics including Harry Houdini, the Donner Party, the advent of television, and the Wright brothers. Primary source material includes pages from a colonial woman's diary, public documents from Truman's presidency, video clips of female pilots, and real audio files of three hobo songs. The site will be especially useful for teachers contemplating using films in the classroom.

The Brooklyn Daily Eagle newspaper was published from 1841 to 1955 and was revived for a short time from 1960 to 1963. This website covers the period from October 26, 1841, to December 31, 1902, representing half of the Eagle's years of publication.

Approximately 147,000 pages of newspaper, in various digital formats, are available. Access can be gained either by date of issue, keyword, or by eight subjects (African American history, Bridges, Crime, Draft Riot, Spanish American War, Women and Women's Suffrage, Arts and Entertainment, and Holidays). A timeline contains detailed information about the creation and development of the Brooklyn Daily Eagle. For an overview, users can browse the newspaper in five-year increments.

It is difficult at times for young people (and people in general) to understand the past, even the more recent past of the past century or so. It seems almost banal to observe that many aspects of life have changed dramatically, and perhaps not so banal to note that many things have in fact not changed as much as we think. This fine site contains a number of interactive exercises (drawing on the vast collections of the American Memory Project at the Library of Congress) that will help deepen students' understanding of common topics in the study of modern America from 1880 to 1920 and to build their skills in analyzing primary sources.

Teachers and student alike will appreciate the "Investigations" area, which contains exercises such as "Picturing Social Change", "Modern Women", and "Picturing Prairie Life". Through the exercises, visitors will be asked a variety of questions that draw on the visual materials contained within each thematic section, such as "What brought people to the prairie?" or "Why might people have left the prairie?". Visitors also have the opportunity to build their own exhibits by choosing their own theme or question about modern America, and through choosing their own images and documents for their exhibit.

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.

Within this site—designed primarily to aide social science researchers and analysts to construct large quantitative studies that can produce analytic results quickly—historians can find studies of importance relating to trends and shifts in American attitudes and opinions. The site presents 12 surveys on race and politics, Italian prejudice, health issues, and voter attitudes since 1952, among other topics.

Perhaps the most useful to historians of the late 20th century will be the General Social Survey, an "almost annual" study since 1972 that has interviewed U.S. households to produce a set of variables covering attitudes on an eclectic range of topics—from abortion to zodiac signs—that have been chosen by experts as "strategic for social science research" and related to public policy. Since 1982, surveys in other countries have replicated questions so that cross-national analyses may be achieved.

Includes data on beliefs concerning welfare, free speech, gun control, class structure, pornography, race, media exposure, working mothers, and women's rights, among other topics. Contains links to eight additional sites that use SDA. Valuable for those studying American social history.

Presents more than 200 items—including 51 articles, 28 lectures, 84 letters, and 35 photographs—by and about the Nobel-winning geneticist Barbara McClintock (1902–1992). Through experiments with maize in the 1920s and 1930s, McClintock discovered that genetic changes occur when chromosomes break and recombine, a process called "crossing over." In the 1950s, upon finding that genes "jump" around, she investigated the effects of transposable genetic elements.

The site includes an exhibit divided into seven chronological sections with a 4,000-word essay presenting McClintock's career highlights, accompanied by links to relevant documents and visuals. Materials in the collection can be retrieved through searches—basic and also geared to scientists—and in chronological and alphabetical listings. Valuable for serious students of genetics as well as those studying the history of American science and professional women.

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.

Documenting more than 5,000 years of sewage history, this site contains a plethora of sources addressing the historical, cultural, engineering, and even literary aspects of sewers. Beginning in roughly 3,500 BCE and continuing into the 20th century, the site includes a detailed timeline of major sewage developments, as well as links to histories of 14 major cities' sewage systems, including Washington, DC and Los Angeles.

In addition to two histories of the modern toilet, there are more than two dozen articles about aspects of sewage design, including short (500–1,000 word) introductions, engineering text, and even PDF diagrams. As well, there is a feature highlighting the many animals found living in metropolitan sewers and a virtual tour of the Paris, France, sewer system. A bibliography introduces users and researchers to major secondary works on sewage and sewer history. A Miscellaneous area collects literary references to sewers, including works by Robert Frost and Ben Jonson.
