On September 14, 1901, American anarchist Leon Czolgosz assassinated President William McKinley, propelling Theodore Roosevelt onto the U.S. political stage and, some historians would argue, making way for political modernization. Through hundreds of documents and images—including book chapters, newspaper articles and columns, sermons, poetry, and government documents—this website explores the McKinley assassination alongside U.S. politics and culture before and after.

Topics include turn-of-the-century journalism, race relations, anarchism, women's roles, the death penalty, international relations, and the Pan-American Exposition in Buffalo, NY, where McKinley was shot. A good place to begin is the "Quotes About" section, which provides short excerpts from a variety of sources that serve to familiarize users with conflicting views of McKinley, Czolgosz, Roosevelt, the assassination, Czolgosz's trial, and anarchism in the United States. All documents are keyword searchable and indexed by date, author, title, type, named persons, and source. An extensive bibliography provides suggestions for further reading.

This website features approximately 20,000 documents relating to President Abraham Lincoln's life and career. All of the materials are available as page images and about half have been transcribed. Resources include correspondence, reports, pamphlets, and newspaper clippings. While the documents date from 1833 to 1897, most material was written between 1850 and 1865, including drafts of the Emancipation Proclamation and Lincoln's second inaugural address. A chronological index offers names of correspondents and document titles.

Special presentations on the Emancipation Proclamation and the Lincoln assassination provide introductions, timelines, and 24 images of related documents and engravings. Additional resources include 16 photographs of the Lincolns and key political and military figures of Lincoln's presidency. This is an excellent resource for researching Lincoln's presidency and American politics prior to and during the Civil War.

The Library of Congress is a well-known and respected content source for the classroom. However, given the wide variety of collections, searching for items on a given topic can be time-consuming. This website links visitors to the library's September 11 resources by collection, so there's no need to run multiple searches.

First and foremost, the website is dated. However, this is no reason to assume that it is without worthwhile content. The exhibit and memorial events it advertises are long past, so the exhibition overview and public programs sections are only useful as primary sources. That said, the collection links are the heart of the site. The American Folklife Center offers a video presentation on the Library of Congress's personal account collection and three drawings by children. For a small collection of chapbooks, a poster, and newspaper clippings, try the Area Studies/Overseas Field Offices collection. The Geography and Map Division provides aerial and fly-through views of the Twin Towers site, while the Prints and Photographs Division's offerings are the most extensive, with posters, fine art, photography, architectural proposals for new World Trade Center designs, political cartoons, and comic book art. Rare Book and Special Collections houses only two photographs of Kitty Caparella's book art, The Message; while the Serial and Government Publications Division's page holds three U.S. newspaper pages announcing the attacks and a video on the Library of Congress's 9/11 newspaper collection.

While the resources are limited, educators who need to find 9/11 materials quickly should consider taking a few minutes on this Library of Congress portal site, particularly if they are interested in items from the Prints and Photographs Division.

Four guided investigations designed to teach students how to read primary sources and construct historical narratives lie at the heart of this website. Topics are: the Spanish-American War, the Scopes Trial, Social Security, and Rosa Parks. Each topic includes a short introductory video, a timeline of events, a central question, and extension activities. For example, the Rosa Parks investigation poses the question: "Why did the boycott of Montgomery's buses succeed?"

After completing a simple login, students read annotated documents—including letters written by the boycott organizers, a speech by Martin Luther King, Jr. and an interview with a woman working in Montgomery—and answer guiding questions, and draw on their responses to answer the question. The website also includes a useful introduction to the idea of historical thinking.

Developed primarily to support a PBS film, this website uses Twain's writings to illustrate his life. An interactive scrapbook, similar to the one patented by Twain, is the centerpiece of the site and provides access to nine chapters of his life. Each chapter is illustrated by period photograph—the scrapbook includes about 100 photographs—and Twain's personal observations. Excerpts of about 15 letters written by Twain are included, as are some 25 news clippings of his lectures, travels, and public appearances. Visitors can also see approximately 20 drawings from first editions of some of Twain's books. The scrapbook offers about 25 audio clips of actors—most notably Hal Holbrook—reading Twain's writings and 15 video clips of the Mississippi River and other sites important to Twain's work. An accompanying chronology lists the events of Twain's life, and Classroom Activities offers five lesson ideas for introducing middle- and high-school students to Twain and his place in American history.

The site asks for sponsorship pledges and markets the video and soundtrack, but overall this site is well designed and offers valuable material for investigating Mark Twain in historical context.

Drawn primarily from documents at the National Archives' National Personnel Records Center, this exhibit explores "the contributions of the thousands of Americans, both military and civilian, who served their country during World War II." Arranged into seven sections--"Prelude to War"; "New Roles"; "Women Who Served"; "The War in the Pacific"; "The War in Europe" "Science Pitches In"; and "The War is Over"--the site presents approximately 60 photographs, editorials, letters, and governmental reports, such as General Benjamin O. Davis's 1943 report concerning racial discrimination in the military. A 3,000-word background essay narrates the materials. Though lacking in depth and limited in size, the exhibit offers a selection of valuable and interesting materials regarding the war effort.

Presents an exhibit on the "United We Stand" campaign of July 1942, a collaboration of the National Publishers Association and the Treasury Department in which approximately 500 magazine publications carried images of the American flag on their covers. The intent of the campaign was to raise public morale and stimulate the sale of war bonds during a time of national anxiety concerning the course World War II had taken. The exhibit includes nearly 300 covers along with a photo-narrative that addresses the history of the campaign and selected aspects of cover design issues. The exhibit also makes an effort to draw parallels to the recent nationwide display of the flag following the September 11th attacks.

Magazine covers are searchable according to subject, title, and keyword. The site includes a 19-title bibliography. Useful for those studying propaganda efforts, the history of business-government wartime collaboration, homefront nationalism, and the history of the magazine publishing industry.

This is a somewhat random collection of material designed to inform visitors about the effects of atomic weapons on Hiroshima and Nagasaki and to encourage discussions about world peace. The Hiroshima City University Department of Computer Science produced the site, which is divided into twenty pages. Pages that address the effects of the bomb include interviews of 700 to 900 words with five survivors and a survey of attitudes of second-generation Hiroshima citizens and children towards the bombing. There are 13 images of objects in the Peace Memorial Museum and 12 photographs that portray the effects of the bomb on Hiroshima. A 600-word essay describes the bomb and its physical effects. Pages that focus on peace include a tour of Peace Park, messages from the Mayors of Hiroshima and Nagasaki, and the 19-page transcript of the Hiroshima Peace Forum, attended by Shimon Peres, Kenzaburo Ooe, and Takeshi Hiraoka. A bibliography provides titles for 37 books about the bomb and links to 30 other bomb related sites. Site may be useful for discussion of the cultural legacy of the bomb.

This exhibit documents the history of the Tacoma Narrows Bridge in Washington State from inception, in November 1938, to collapse, in November 1940, and eventual reconstruction in 1950. In 1940, the original structure was the third longest suspension bridge in the world. The bridge was initially referred to as "the Pearl Harbor of engineering," but the wavelike motion the bridge displayed soon earned it the nickname "Galloping Gertie." The exhibit divides the history of the infamous bridge into five themes--construction, opening, collapse, aftermath, and reconstruction--each with 15 to 30 photographs and newspaper articles accompanied by 50- to 100-word captions. A bibliography of more than 30 items rounds out this online exhibit and those interested in the impact of the bridge on the Gig Harbor Peninsula residents should visit the link Gig Harbor Museum. This is also a valuable site for anyone interested in engineering, aerodynamics, and Pacific Northwest history.
