These multimedia resources for teaching American history focus on slavery, ethnic history, private life, technological achievement, and American film. There are more than 600 documents on the history of Mexican Americans, Native Americans, and slavery, from "first encounters" through the Civil War.

A complete U.S. history textbook is presented, along with historical newspaper articles and more than 1,500 annotated links, including 330 links to audio files of historic speeches, and nine links to audio files of historians discussing relevant topics. Ten essays (800 words) address past controversies, such as the Vietnam War, socialism, and the war on poverty. Seven essays present historical background on more recent controversies and essays of more than 10,000 words each address the history of American film and private life in America. Exhibits offer 217 photographs from a freedmen's school in Alabama and seven letters between 18th-century English historian Catharine Macaulay and American historian Mercy Otis Warren.

Created in 1995, this site presents an impressive body of primary and secondary source materials about the Holocaust. Offers an wide range of contemporary and historical resources, including more than 100 images from concentration camps and the Warsaw ghetto; more than 30 drawings and paintings by Holocaust survivors; interactive maps of two concentration camps; the text of the 1942 Wannsee Protocols; four interviews with historians; lesson plans for teaching about the Holocaust to school children; background essays; survivor narratives, poetry, and literature; letters, speeches, and posters by Nazi perpetrators; and scores of links. A sophisticated search engine guides users through the site's poorly organized and sometimes confusing interface. The site's author is a website marketing consultant. Particularly useful for secondary school teachers seeking to design student projects, this is an extremely rich collection of material.

IWitness is an incredible resource for educators intent on bringing awareness and analysis of the Holocaust to their classroom. The site offers more than 1,000 video testimony clips from Holocaust survivors, liberators, and others. These videos can be browsed by topic (from "Anti-Jewish Laws" to "Warsaw Ghetto Uprising") or searched by name or topic. Searching provides a few benefits for lesson planning. For one, video search results will play the portion of a clip containing information related to your search, making it easy to decide if the result is actually relevant to your classroom plans. In addition, searches may reveal related materials such as photographs of artifacts in the U.S. Holocaust Memorial Museum collection or encyclopedia articles providing additional information and context.

You can also register as an educator or a student. Educators can assign activities and view student work (only viewable by the specific student and the teacher). Students can watch videos on items such as understanding testimony and archives or editing video interviews in an ethical manner. Activities that call for video editing allow students to save clips into a library for future use in their projects and prepare their own videos using video-editing tools which are part of the website—no download needed.

For a quick introduction to the site, consider watching the six-minute demonstration video linked at the top of the About Us page.
