Presents statistic tables showing trends in crime and law enforcement operations at state, local, and national levels. Users can find tendencies in types of crimes, types of victims, and types of weapons based on figures voluntarily reported to the FBI by state law enforcement agencies from 1960-1999, and by local agencies from 1985. In addition, statistics concerning law enforcement operations for states and large local agencies are searchable according to variables such as demographic composition of police forces, function, salary, and employment and training requirements. Valuable for those studying American social history, urban history, and human geography, in addition to students of the U.S. criminal justice system.

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.

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.

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.

A chemical manufacturer has put together this site containing 638 full-length audio files of ragtime music, tunes "highly influenced by the genre," and music "evocative of the times" in which ragtime was produced. Music may be downloaded at no cost. Also provides 26 classical pieces.

Includes notes for many of the ragtime pieces of up to 800 words each, and 19 biographies of 100–600 words each on composers and performers, including Scott Joplin, Charles Hunter, and Joseph Francis Lamb. The music is available through MIDI files. Of interest to those studying music history and popular culture.

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.

This website offers resources in Washington history through three main sections: historical records research, historical newspapers and classics in Washington history, and presentations. Historical records offers county census records, naturalization records, other miscellaneous records, and genealogical research resources, as well as searches of the state archive records and the state library catalog.

The three sections of this website focus on women lawyers in the U.S. and women's legal history. The Women's Lawyers Index offers more than 700 listings of female lawyers in U.S. history, each with links to biographical information, collected papers and archival material (if available), and articles, as well as a bibliography. The content of these sections is uneven, though, some having far more entries than others.

The Clara Shortridge Foltz section primarily consists of 13 articles by Babcock on Foltz, the first female lawyer on the Pacific Coast. It focuses on the relation of early women lawyers to suffrage and other reform movements.

"Research Resources" provides 23 links to other websites on women lawyers and women's legal history, as well as over 50 links to historiographical articles, articles from periodicals and legal journals, and general interest articles.
