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.

Provides approximately 135 texts—primarily published books, but also pamphlets, journal articles, and 36 slave narratives—that illuminate "how Southern African Americans experienced and transformed Protestant Christianity into the central institution of community life." Also focuses on how blacks coped with disenfranchisement, segregation, and bigotry.

Includes a number of texts written by African American scholars in the early 20th century. Includes a 15-title annotated bibliography and a 2,000-word introductory essay. Valuable for the study of African American history, the history of American religion, history of the South, and 19th-century American cultural history.

More than 400 items, including approximately 380 photographs, on the Wright Brothers' "early inventive period documenting their experimental gliders and flight testing in both North Carolina and Ohio." Most of the materials date from 1897 to 1908. Approximately half of the photographs were taken in the Outer Banks, NC. In addition to recording the Wrights' aviation trials, these images provide "a valuable record of their home life, camp life, and the flora and fauna" of the area.

More than 70 images were taken at Le Mans, France, and approximately 25 at Fort Myer, VA. The Wrights themselves produced more than 180 photos, and fellow flight pioneer Octave Chanute shot approximately 35. The site, which promises future additions, allows browsing by date, object type, place, and creator, and is fully searchable. Primarily of interest for those studying early flight history.

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 photographic archive contains more than 1,500 images commissioned by the Pittsburgh Department of Public Works, Division of Photography, from c1890 through 1973. "The images show Pittsburgh parks, recreation facilities, and athletic events as well as hospital exteriors and interiors, mayoral events, traffic situations, and general street scenes."

The image collection emphasizes interior and exterior photographs of familiar and historic buildings and "interesting depictions of home life, and the famous and not so famous people of Pittsburgh." Each image is accompanied by bibliographic and descriptive information. The archive can be searched by image title, date, creator, location, address, description, or subject. A useful resource for those interested in urban development, city life, and architecture.

This archive of American popular songs in their original form allows the user to explore the history of popular music in the U.S. from the 1850s to the present.

The collection includes a wide variety of music genres, from music for theater, television, and motion pictures to rhythm and blues and rock. The collection can be browsed by name, title, cover art subject, or date. Or search the archive by keyword or combination of keyword, title, description, composer, or publisher. There are 12 links to other digital sheet music collections. Those researching American popular music should find this extensive collection very useful.

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.

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.
