This well-designed site presents the Nebraska edition of the Lewis and Clark journals, edited by Gary E. Moulton. The site provides the complete text of all the journals from the 1803–1806 expedition, as well as introductions, prefaces, and sources. The material is searchable by keyword and phrase.

There are 29 scholarly essays about the expedition. An image gallery offers 124 images of pages from the journals, 95 images of people and places, and 50 images of plants and animals encountered on the expedition. The maps section includes 12 explanatory maps and nine images of maps from the journals. Additionally, there are 27 audio excerpts of journal readings and eight video interviews with the editor of the project. The website stands as an outstanding resource for researching the history of the Lewis and Clark expedition.

Presents a narrative in exhibit format—with hyperlinks to archival documents and photographs—on the cultural and economic life of the people who came to the Central Illinois River region from 1875 to 1950. Organized into three sections on the harvesting of fish, waterfowl, mussels, and natural ice; transportation by boat, railroad, and plank roads; and the settlement and development of six area river towns. The site delivers oral histories (audio and video), as well as illustrations and photographs. It may serve as a useful introduction to those studying this particular region and regional history in general.

The history of Jews in America from the 17th century to the present is explored in this website through essays, images, video presentations, and interactive timelines. Eight sections focus on particular time periods: 1654–1776; 1777–1829; 1830–1880; 1881–1919; 1920–1939; 1940–1948; 1949–1967; and 1968–present. Each section has short topical essays discussing the world events, politics, and daily life of the period, video and audio presentations, an image gallery, and books for further reading.

A number of sections also have "featured artifacts" that examine a particular cultural artifact, such as a Colonial-era book of prayers or a Civil War photo album, in greater detail. Each thumbnail is accompanied by a description and a full-sized image. The 590 images in the collection can also be viewed in a separate gallery.

This interactive website on the attack on Pearl Harbor provides a chronological overview of the day's events. Each major event on the day's timeline is shown on a map of Hawaii, giving the events a visual place within the harbor geography and allowing site visitors to see where ships were in relationship to each other.

On the map, each major occurrence can be selected as the "full story." These individual full story pages provide a short textual overview of the event alongside a looping archival image and video slideshow. Clicking progresses through the slideshow for users interested in quickly revisiting an image after it has passed or who simply want to go through the slideshow at a faster pace. Many of the events also offer eyewitness quotes.

One of the most praiseworthy aspects of the site is that these quotes are not all from U.S. sailors and commanders. The voices selected include two women—a nurse and the daughter of a military man—and several Japanese airmen, submariners, and commanders. By providing voices from both sides of the attack, National Geographic avoids dehumanizing the Japanese through the absence of their own stories.

Created by the staff of the Annenberg Rare Book and Manuscript Library at the University of Pennsylvania, this exhibit traces the life and musical career of African American contralto Marian Anderson. Anderson broke the race barrier when she came to prominence in the 1930s and 1940s. The materials are drawn from Anderson's personal papers, which she donated to the University of Pennsylvania in 1993. The exhibit is presented chronologically in 10 sections that explore Anderson's birth in Philadelphia, her education and musical training, and her career and humanitarian efforts toward improving African Americans' opportunities.

The site contains more than 30 audio and six video excerpts from performances and interviews, over 50 images, with approximately 100-word explanatory captions, illustrating Anderson's life and work. This exhibit is ideal for researching African American history and the history of the performing arts in America.

A companion site for a PBS American Experience documentary on the Women Airforce Service Pilots, or WASPs, who flew military support missions during World War II. More than 1,000 women participated in the program, marking the first time women piloted aircraft for the U.S. Army. The site includes 16 documents—including official correspondence, letters, and certificates—and transcripts of interviews with two of the pilots, a historian, and a general. Additionally, it offers a transcript of the complete one-hour broadcast; a 3,430-word excerpt from a book by a WASP test pilot; biographies of approximately 1,200 words each of three WASP pilots and three female pilots from earlier times; two video clips; a 2,100-word introductory essay; and a 1,000-word history of the B-29, a dangerous bomber WASPs flew in order to convince resistant male pilots that the plane was safe.

The site also provides a timeline, a bibliography of 22 titles, and a reference guide for teachers. With its emphasis on the experience of these pilots as women—they suffered ridicule, attacks in the press, and possibly even sabotage to their aircraft, then disbanded in December 1944 when male pilots lobbied for their jobs—the site will be of interest to those studying women's history, in addition to military history.

There are countless websites which catalog web activities related to the spread of information on 9/11. However, film is another way to approach research on the day. At what time did news of 9/11 break in China? Japan? Iraq? Russia? How did news coverage vary from one U.S. news station to another?

This archive contains television coverage arranged in visual timelines by day and channel. This format allows users to easily compare the information being aired at the same time by NBC, FOX, BBC World, and Japan's NHK—to name just a handful. Additionally, the timeline permits educators to find clips broadcast at specific times between 9/11 and the 17th of September.

The website also includes 10 talks given at a scholarly conference about the implications of film archives in historical research.

Note that foreign news channels have not been subtitled.
