A quarterly journal inaugurated in September 2004 designed to "promote the study of American history" with articles by historians and teaching resources. Past issues on elections, primary sources on slavery, immigration, and American national holidays are also available on the site.

Each issue has six main features. "In This Issue" provides an introduction and overview. "The Historian's Perspective" offers four to six scholarly essays by noted historians on the issue's topic. "From the Teacher's Desk" has lesson plans for high school, middle school, and elementary school levels with links to related websites. "Interactive History" provides either timelines, quizzes, or interactive maps. The "Digital Drop Box" allows site visitors to post comments, suggestions, sample lesson plans, or stories from the classroom. "Ask the Archivist" has suggested sources and a section for questions and answers.

Offers hundreds of lesson plans composed by teachers, on a variety of subjects, organized into three groups—K-5, 6-8, and 9-12. Provides 31 plans for grades 9-12 on U.S. history topics, including civil rights, balancing budgets, jazz, opposing views of the Vietnam War, Native American history, the Cold War, Japanese-Americans during World War II, racism, NATO, the Salem Witch Trials, U.S.-Cuba relations, and "The Power of Fiction," focusing on socially-relevant texts. Also includes 33 Literature plans—many on works by American authors—and plans for world history and ancient history. Valuable for high-school level history teachers.

The history of the eugenics movement in the United States, from its inception in the decades following the Civil War through its height in the first few decades of the 20th century, is traced on this website. As we move into the age of genetics, this movement, that sought to filter "bad" traits from the human population, becomes increasingly important to understand.

The movement's history is told through a narrative divided into eight themes, including social and scientific origins, research methods and traits studied, flaws in these methods, ways in which the movement was popularized, immigration restriction, and marriage and sterilization laws. Each narrative is accompanied by roughly 10 primary sources—reports, articles, charts, legal documents, and photographs. These materials provide a succinct introduction to eugenics in the U.S.

In addition to the narratives, visitors can search or browse the Image Archive, featuring more than 2,000 primary sources, including documents, artwork, photographs, and more. Visitors may browse by topic, object type, time period, or the archive sources' originals are held by, or search by keyword or ID number. Note that primary sources cannot be downloaded from the Flash version of the Archive, though they can be from the HTML version of the site.
