Providing a host of resources on U.S. history survey, the three main features are: WWW.History, Many Pasts, and Making Sense of Evidence.

WWW.History provides an annotated guide to more than 1,000 high-quality websites covering all of U.S. history. Users can browse websites by time period or topic and can search by keyword.

Many Pasts offers more than 1,000 primary sources in text, image, and audio, from an exchange between Powhatan and Captain John Smith to comments by the director of the Arab American Family Support Center in Brooklyn after the September 11, 2001, terrorist attacks.

Making Sense of Evidence offers eight guides with interactive exercises designed to help students learn to analyze various kinds of primary sources, including maps, early film, oral history, and popular song. These guides offer questions to ask and provide examples of how to analyze kinds of evidence. There are also eight multimedia modules that model strategies for analyzing primary sources, including political cartoons, blues, and abolitionist speeches.

DocsTeach, a National Archives and Records Administration project, recognizes the need to bring primary sources into your classroom. To assist in the effort, NARA has pulled together thousands of primary sources, as well as a selection of pre-made activities and tools for building your own primary-source-centric activities.

Documents offers exactly what it sounds like it would—primary sources. The sources are divided into chronological categories—Revolution and the New Nation, Expansion and Reform, Civil War and Reconstruction, Development of the Industrial United States, Emergence of Modern America, Great Depression and World War II, Postwar United States, and Contemporary United States. Results can then be narrowed further by selecting audio/visual, charts/graphics/data, image, map, or written document. If you prefer, you can use a keyword search. All search results are shown with thumbnails to give you a small preview of the sources for your consideration.

Activities provides pre-made classroom activities. These require access to a computer, and are based on the same tools which the site provides for making your own activities. You can also sort them by historical thinking skill—chronological thinking, comprehension, analysis and interpretation, research capabilities, and issues-analysis and decision-making. Registering gives you access to a much larger collection, many of which are created by other educators. There is no registration cost.

If you're registered, consider making your own activity for use by yourself and others. There are tools which help students to create sequences, participate in analytical discussion, connect documents, geographically map documents, use documents to gain an understanding of the bigger picture, weigh evidence, and examine source context.

Take a moment to peruse the Teacher Resources as well. Here, you can find information on national history standards, using DocsTeach activities in the classroom, Bloom's taxonomy, and the National Council of Social Studies.

Throughout the Ages was created to meet the primary source needs of New York state K-6 history teachers. The site collection includes more than 500 photographs, letters, paintings, advertisements, and maps.

To navigate the site, choose an area of interest and subtopic (for example "leisure" under the heading "community"), and scroll to a source of interest. The source will offer a caption. In some cases, historical context, focus questions, and the correlating New York state standards will also be listed. Be sure to click on each of these section titles, as items such as resources and historical background only display once selected.

One feature to look into is the automatic handout maker. For each image, you can automatically generate a handout by selecting any or all of the following categories: caption, historical background, standards/key ideas, historical challenge, interdisciplinary connections, and resources. For some images, these will already be filled out. For others, you can type anything you want for all, some, or one of those categories. Don't worry about deleting existing text if you don't want it on your handout. It will be back the next time you load your page.

This vast collection of more than 275,000 digitized images sheds light on many aspects of 20th-century life in Los Angeles, especially the entertainment industry, politics and public issues, and suburban life. The collection is especially strong in images depicting the growth of LA from the turn of the century through its growth spurt between 1920 and 1939, including a series of promotional images designed to attract Midwesterners and east coast businesses to "the City with Promise."

The collection also includes more than 10,000 photographs drawn from the family albums of a diverse group of Los Angeles residents.

Images can be accessed through a keyword search and limited by date range, though browsing is not yet available. In addition, users can add images to a "personal list" which can then be sorted by author, title, or call number and emailed/printed.
