The Platte River begins in the Rocky Mountains and flows the length of central Nebraska before emptying into the Missouri River to the east. This website provides 40 diverse documents about the history, geology, and hydrology of the Platte River, ranging in date from an 1843 report by the U.S. Secretary of War entitled "An Exploration of the Country Lying Between the Missouri River and the Rocky Mountains," to a 302-page report published in 1993 by the Nebraska Geological Survey entitled, "Flat Water: A History of Nebraska and Its Water." The majority of documents date to the 1970s, many of which were published by government agencies such as the Missouri River Basin Commission or the U.S. Department of the Interior Geological Survey, detailing investigations into ground water usage and water resources management. There are also several documents on legal issues surrounding water rights and outdoor recreation. These materials are accompanied by 13 links to websites offering information about water resources, including the University of Nebraska's Water Center and Water Sciences Laboratory, as well as the Missouri River Basin Project, created to plan for the conservation and use of Missouri River water resources. Especially useful for those interested in the history of development projects surrounding water resources.

Curated by Carl Smith, Professor of English and American Studies at Northwestern University in a collaborative effort with the Chicago Historical Society, this rich site provides an online exhibit commemorating one of the most notorious incidents in late-nineteenth-century labor history, the Haymarket Affair. On May 4, 1886, two workers were killed in a struggle between police and locked-out union members at the McCormick Reaper factory. On May 5, 1886, someone threw a dynamite bomb into a group of Chicago policemen sent to control the ensuing protest, killing seven. This site is an online exhibit of selected materials from the Chicago Historical Society's Haymarket Affair Digital Collection. Organized in the form of a drama, the site contains a prologue, five acts, and an epilogue, all arranged chronologically.

The prologue, "Whither America," covers the period between Chicago's Great Fire in 1871 through 1880, with emphasis on the railroad strike of 1877 and other developments in the radicalization of American workers. Act I, "Subterranean Fire," discusses the widening class divisions and resulting rising level of violence in America. Act II, "Let Your Tragedy be Enacted Here," recounts the demonstrations of 1886, the protestors' meeting, and the bombing. Act III, "Toils of the Law," covers the legal proceedings beginning with the "red scare" and police "witch hunt" following the bombing and continuing through the sentencing of the convicted anarchists in October 1886. Act IV, "Voice of People," relates the legal and public appeals ending with the executions of 1887. Act V, "Raising the Dead," moves from the funerals of the executed men to Governor John P. Altgeld's pardon of the surviving defendants in 1893.

The epilogue, "Drama Without End," deals with the contested heritage of Haymarket, including centennial events in 1986. Each part consists of a 500-word interpretive essay and topical sections including a total of over 50 visual materials, such as images of artifacts, photographs, and engravings of the people involved in the Haymarket Affair, and over 30 facsimiles of selected manuscripts and printed materials. Each "Act" contains a final section that includes full-text transcriptions of documents from the Haymarket Digital Collection. The site also includes virtual tours of the Haymarket area and of Forest Home Cemetery, where a monument to the convicted men is located, and audio recordings of contemporary labor songs. This site is beautifully contextualized, well-presented, and easy to navigate. It contains a keyword search engine as well as a table of contents.

In 1868, President Andrew Johnson was impeached for violating the Tenure of Office Act (1867), which prohibited a president from unilaterally removing any officials for whom Senate approval was required for appointment. Part of Professor Douglas Linder's Famous American Trials website, this exhibit examines Johnson's impeachment trial and his narrow escape from conviction and removal from office. Linder provides a 1500-word account of the trial and includes a chronology of events in Johnson's presidency, from his election as Abraham Lincoln's vice president in 1864 to his death in 1875. The site includes background information on the process of impeachment, such as the relevant articles of the United States Constitution and James Madison's notes on the framers' Constitutional Convention debates over the impeachment process.

The site also includes full-text verions of the Articles of Impeachment against Johnson, the Senate's rules of procedure for the impeachment trial, and the Senate trial record, including all arguments, documentary evidence, testimony, and the final vote. There are also excerpts from the Congressional Globe of the opinions of six senators, both for and against impeachment, and a map that shows the regional splits in the votes for and against impeachment. The site also provides links to the Harper's Weekly account of the trial, including biographies of 28 key figures in the trial, 90 editorials, 47 news articles and briefs, 47 illustrations, 27 political cartoons, and one illustrated satire. A brief bibliography includes six scholarly books, one video, and two internet sites with information on the Johnson impeachment trial. The Harper's Weekly section also provides a link to a "Teaching Impeachment" exercise in which students can simulate an impeachment trial. This rather complicated role play exercise requires considerable research and strong analytical skills, but would be accessible for very advanced high school and survey classes. This is an ideal site for researching constitutional history, Reconstruction, and the presidency.

In April 2000, the Gerald R. Ford Library released approximately 40,000 pages of classified documents concerning the Vietnam War. Many are from National Security Advisors Henry Kissinger and Brent Scowcroft and their staffs and deal with the decision to evacuate U.S. forces from Vietnam in April 1975. This site provides 15 samples of the newly declassified material, 27 additional documents related to the war already available, 17 photographs of Ford and his advisors during meetings, and finding aids for those planning to travel to the Ford Library in Ann Arbor, Michigan. The sample documents include important memos, letters, and cables regarding corruption in South Vietnam; "ominous developments" by the North Vietnamese reported to Kissinger in March 1975; the evacuation decision and its execution; the seizure of the U.S. merchant ship Mayaguez by a Cambodian gunboat crew in May 1975; the plight of Vietnamese refugees; "lessons of the war" imparted to Ford by Kissinger; and notes from Scowcroft to Ford on the then-ongoing reconstruction of Cambodian society by the Khmer Rouge.
