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.

Especially since the 1950s, civil rights litigation has done much to influence government institutions. This website presents at least partial information on 2,243 injunctive civil rights cases (those seeking policy change and not money). These cases are divided by category. "Jail Conditions" and "Prison Conditions" contain the most cases, with roughly 550 each. "Immigration" and "Juvenile Institutions" also include more than 150 each. Other categories include: "Mental Health Institutions," "Mental Retardation Institutions," "Child Welfare," "Nursing Home Cases," "Policing Cases," "Public Housing," "Equal Employment," and "School Desegregation," among others.

A good place to begin is the "Featured Cases" section on the website's homepage, which highlights cases from the collection that are being litigated currently and/or that are particularly relevant to current events. Cases are fully searchable by name, type, issue, district, circuit, state, causes of action, attorney organization, and people involved in the case. In addition, links to 141 case studies written by law students, professors, journalists, and policy advocates provide in-depth information on a specific case or issue, such as the Urban Institute's "Baseline Assessment of Public Housing Desegregation Cases." New material is added regularly.

More than 300 U.S. government publications from World War II have been digitized for this site, an ongoing project that plans to add another 200 documents.

Materials include pamphlets and books emphasizing home front issues, such as air raids, preservation, child labor, and victory farms. All materials are searchable by title, author, subject, and keyword. Browsing is also available.

A companion collection of photographs, the "Melvin C. Shaffer Collection," depicts the home front situation in Germany, North Africa, Italy, and Southern France from 1943 to 1945. Shaffer was a U.S. Army medical photographer assigned to document the medical history of the war through major campaigns. Shafer took the photographs on this site—totaling approximately 340—unofficially with the goal of recording the war's impact on civilians.

StoryCorps is a nonprofit organization dedicated to collecting and preserving the stories of people across the U.S. Founded in 2003, it has collected more than 15,000 stories from people in all walks of life—immigrants, veterans, those that suffer from debilitating diseases, lovers, September 11th survivors, and many more. Each recorded conversation includes two or three people, often grandchildren interviewing grandparents, old friends interviewing each other, or children remembering their parents. Clips, usually between two and five minutes, from hundreds of these stories are available.

The clips are keyword searchable and browseable by category: Angels & Mentors, Discovery, Friendship, Griot, Growing Up, Hurricane Katrina, Identity, Romance, September 11, Struggle, Witness, Wisdom, and Work. Many people discuss their involvement in World War II or the Vietnam War, and many more talk about how they met their spouses or coped with segregation. Always thought-provoking, and often moving, these clips can expose the more human side of major 20th-century events.

This site offers an online exhibit and an image database of more than 70 historic educational visual aids created for use by schools, libraries, and museums beginning in 1935 by the WPA's (Works Progress Administration) Museum Extension Project. The collection features items such as puppets, toys, architectural models, dioramas, jigsaw puzzles, handbooks and pamphlets, lantern slides, miniature furniture models, prints, and posters. Each item contains information about its size and place of production.

The collection is searchable by item and by state of manufacture and contains materials from Connecticut, Illinois, Kansas, New Jersey, Pennsylvania, and Wisconsin. Suitable for those interested in material culture or government-sponsored education projects.
