Africans In America
This is a remarkably detailed web site that chronicles the experience of Africans in America up through the Civil War, dividing the experience into four periods. For each of these periods the site provides a wealth of resources that will help teachers. These materials include resource banks with primary sources and historians' brief responses to specific questions. The site also offers teachers' guides and lesson plans, many of which revolve around the PBS documentary also entitled Africans in America, links to additional web sites, and short bibliographies.

American Memory
This site is part of the Library of Congress and contains a wealth of images, audio files, and documents related to American history.

Center for History and New Media
George Mason University hosts this site, one of the most useful sites for teachers. While the main page has nice collections of useful web sites, including a fantastic site on the French Revolution, most teachers will go immediately to the History Matters site. The History Matters site includes a searchable collection of primary sources, dozens of lesson plans using primary sources available on the web, a syllabus depository, and an annotated list of 100s of web sites and web site reviews.

eHistory
OSU's eHistory site features maps, images, book reviews, and a long list of "MultiMedia Histories" as well as a section of articles called "Origins: Current Events in Historical Perspective." Additionally the site contains the full text of John Guilmartin's book America in Vietnam and a dozen other texts on US wars, along with the complete (and searchable) Official Records of the Union and Confederate Armies.

National Archives Digital Classroom

West Web
Created and maintained by a professor of history at the College of Staten Island, West Web offers a topical look at all things Western. Although not all of the sections are completed, all do provide links to other recommended sites for information. Of particular interest to the U.S. history teacher will be the sections on "Teaching Western History," "The Mechanical Eye"-a guide to sites with photographs of the West, "Children of the Sun"-a guide to information on native peoples and archeological projects in the West, and "Making it on Their Own"-a collection of primary and secondary sources about women's lives in the West.
