"Presidential Tax Returns" includes returns of recent presidents and Vice President Cheney. "Taxing Federalism" features nine Federalist Papers, and "Image Gallery" offers 15 political cartoons from the turn of the century to 1947, many by Washington Star cartoonist Clifford Berryman. The site also offers a bibliography and four sound clips of federal officials discussing tax policy.

The Dred Scott case began in 1846 when slaves Dred and Harriet Scott sued for their freedom, basing their argument on the fact that they had lived in non-slave territories for a number of years. The case ended with the landmark U.S. Supreme Court decision of 1857 that not only denied Scott both citizenship and the right to sue in federal court, but ruled that he never had been free and that Congress did not have the right to prohibit slavery in the territories. The decision sparked increased sectional tensions in the years leading to the Civil War. Facsimiles and transcriptions of 85 legal documents relating to the Dred Scott case are provided on this website. The site also provides a chronology and links to 301 Freedom Suits—legal petitions for freedom filed by or on behalf of slaves—in St. Louis courts from 1814 to 1860.

On March 25, 1911, a fire broke out at the Triangle Shirtwaist Factory in New York City causing the deaths of 148 garment workers—an event that came to be known as one of the hallmark tragedies of the industrial age. This website tells the story of the fire in six chapters: Introduction; Sweatshops and Strikes; Fire; Mourning and Protest; Relief Work; and Investigation, Trial, and Reform.

The text, targeted to a middle and high school audience, is accompanied by numerous primary sources that could be of use to more advanced researchers. These include close to 70 photographs, 18 newspaper articles, 17 testimonials, three oral histories, excerpts from investigative reports written in the years following the fire, several letters from witnesses, a lecture given by Secretary of Labor Frances Perkins in 1964, and a radio drama reenacting the event. Accompanying these primary sources is a list of victims and witnesses, a selected bibliography of works surrounding the fire, and tips for writing a paper.

This collection of documents—roughly 3,800 pages of court proceedings—concerns the Haymarket Affair. This watershed event in the history of American radicalism led to the first "Red Scare" in America. Materials include autobiographies of two of the eight anarchists tried for conspiracy in the murder of seven Chicago police officers. The officers died after a bomb exploded at an anarchist meeting in May 1886, the day after two workers died in a struggle between police and locked-out union members at the McCormick Reaper factory. Four defendants were executed, despite lack of evidence connecting them to the bombing. The site presents approximately 221 newspaper clippings, 55 photographs, 19 letters, nine broadsides, and images of more than 20 artifacts. A linked exhibition, "The Dramas of Haymarket," furnishes a historical narrative and contextual interpretation. This website is valuable for the study of late 19th-century American radicalism, law enforcement, and political climate.
