This wealth of data presents National Election Studies surveys of the American electorate conducted in presidential and congressional election years from 1948 to 2006. Large files of raw data can be downloaded. In addition, The ANES Guide to Public Opinion and Electoral Behavior is available and is readily accessible.

Composed of more than 100 tables and graphs, the guide traces nine key variables in the makeup and opinions of the electorate. These include: social and religious characteristics; partisanship and evaluation of political parties; ideological self-identification; public opinion on public policy issues; support for the political system; political involvement and partisanship; evaluation of presidential candidates; evaluation of congressional candidates; and vote choice. This website also provides pilot studies on recent surveying issues, such as measuring exposure to television advertisements, and a 5,000-item bibliography.

Records on the more than 25 million passengers and ship crew members who passed through Ellis Island between 1892 and 1924 are available through this website. Most passengers came from Europe and Russia, although there are some records from Asia, the Caribbean, and Latin America.

The website requires a free, simple registration to view detailed records that include name, residence, date of arrival, age on arrival, ethnicity, place of residence, marital status, ship of travel, place of departure, and a copy of the original ship manifest (a transcription is also available). The website includes extensive contextual information about Ellis Island, immigration, and genealogical research. "Family Histories" illuminates the genealogical research experiences of six Americans of diverse ethnic backgrounds.

The "Peopling of America" exhibit covers six periods from pre-1790 to 2000, with graphs, photographs, and immigration statistics geared to place of origin. Additional information is available for an annual fee.

This American Battle Monuments Commission (ABMC) Burials and Memorializations database features over 224,000 records of individuals buried or memorialized in ABMC cemeteries and memorials worldwide. Covering 24 cemeteries in 10 foreign countries and 3 additional memorials in the U.S., this database provides online access to burial information of those killed in action primarily during World War I, World War II, the Korean War, and the Vietnam War.

Additional individuals include veterans, active duty military, and civilians. The database also provides information on individuals in the Corozal American Cemetery (Panama) and the Mexico City National Cemetery (Mexico), including civilians and veterans of the Spanish-American War and the Civil War.

The database interface allows students to search by name, war or conflict, service or serial number, branch of service, unit, service entry location, cemetery/memorial, date of death, and keyword. Users can also search for service members who are missing in action and Medal of Honor recipients who are buried or memorialized by ABMC.

This organization of the material allows the user to explore a wealth of information. Students can research the geographic distribution of burials or explore representation among military branches in individual cemeteries. The ABMC database allows users to focus on who is buried and memorialized and to explore the experiences of individual soldiers as well as patterns and commonalities.

Students, for example, could begin to explore the number of women who served as nurses during World War I and the Influenza epidemic of 1918, or the experiences of the 100th Infantry Battalion of the U.S. Army during World War II. Or they could chose to search for an individual from their home state or community and use the database’s information as a starting point to research the life of this individual. They can download search results and print, email, or share individual records.

This valuable research and teaching resource is accompanied by a robust “Education Resources” section featuring interactive timelines and campaign narratives, cemetery or memorial-specific mobile apps, publications, videos, lesson plans, and curriculum ideas. The “Flying Yanks: American Airmen in WWI” interactive, for example, provides historical background for students exploring the air war in WWI, a timeline and map with primary sources, as well as individual stories of airmen.

Students can use the database in conjunction with the learning materials to enrich their understanding of U.S. military history, memorialization, public history, and numerous other historical topics.

The Civilian Public Service Story answers the question, "Did individuals conscripted for World War II who were strongly opposed to killing have to fight?" The answer, something rarely discussed, is no. In the words of the site's introductory page, "Civilian Public Service (CPS) was a program developed at the onset of WWII which provided those whose conscience forbade them to kill, the opportunity to do work of national importance under civilian direction rather than go to war. Nearly 12,000 men made this choice, and many women voluntarily joined the cause. They fought forest fires, worked in mental institutions, planted trees, did dairy testing and served as subjects for medical experiments in more than 150 camps scattered throughout the United States."

The section "The Story Begins" consists of a brief summary of the history of conscientious objection in the U.S., beginning with colonial times. You can also find an annotated bibliography, listing approximately 18 works. Note that these works, and this site in its entirety, are intended for adult users. However, this does not preclude the information from being useful for K–12 history education.

"The People" consists of a few statistics on the World War II CPS population as well as a database of the men and women of the CPS, reproduced with permission from the Center of Conscience and War. These records, searchable and alphabetized by last name, may include year of birth, community, religious denomination, CPS entrance and exit dates, spouse, camps and units, higher education, and pre- and post-CPS occupation. These records may be of the most use in a classroom setting, as they could spark local history or oral history projects. "The Camps" provides a similar feature. Consider looking into CPS camps that were in your area using the map application on the site.

Visitors to this site will find more than 1,000 images and dozens of videos about the history and culture of Puerto Rico. The work of dozens of scholars and contributors, the Puerto Rico Encyclopedia reflects the diverse nature of the island: a U.S. territory, a key location for trade in the Caribbean, a Spanish-speaking entity with its own distinct culture, and a part of a larger Atlantic world. Funded by an endowment from the National Endowment for the Humanities and the Fundación Angel Ramos, the site is a key product from the Fundación Puertorriqueña de las Humanidades. It provides users with all content in both English and Spanish. Educators will find the site easy to navigate and conveniently categorized by themes; within each topic, appropriate subtopics provide an in-depth examination of Puerto Rican culture and history. Of particular interest to U.S. History teachers are the images and information found under History and Archeology. Here, teachers and students can explore a chronological narrative of the island's history and role at specific moments in U.S. and Atlantic history. Other sections worth exploring are Archeology (for its focus on Native American culture), Puerto Rican Diaspora (for its look at Puerto Ricans in the U.S.), and Government (for a detailed history on Puerto Rico's unique status as a free and associated US territory). Educators in other social science courses will also find valuable information related to music, population, health, education, and local government. In all, 15 sections and 71 subsections provide a thorough examination of Puerto Rico. The Puerto Rico Encyclopedia's bilingual presentation also makes it a good site for integrating Hispanic culture into the U.S. History curriculum, as well as helping to bridge curriculum for English Language Learners (ELLs) in the classroom.

The Living New Deal project essentially creates a Google map of projects completed within the United States as part of the economic and social revival measure, the New Deal. These maps can be sorted by the type of project you are interested in locating, such as education, parks, art, or flood erosion measures. You can also find the portion of the nation of interest to you, and use the maps to locate nearby New Deal examples. Time for a field trip, perhaps?

In addition to providing the name, address, and website link for each location, the Living New Deal project also includes numerous other resources—such as detailed project descriptions, names of contributors and/or artists, project dates, photographs, and many other helpful and informative tid bits of information. The site also offers a plethora of other resources, so be sure to search around for teaching resources centered on the New Deal, news updates about existing New Deal projects, and coverage of the current economic crisis.

Although the website asks for contributions on the main page, users are under no financial obligations whatsoever. Contributions of information (to be verified by UC Berkeley) are also welcome, and likely more professionally appropriate.

This website gathers together documents concerning the history of National Park Service properties.

Navigation is simple. Just select your park of interest from the drop-down list, and you will be brought to a list of all of the available documents for that particular location. Documents include structure reports, administrative histories, physical and cultural landscape reports, studies of historic resources available, management regulations, conference proceedings, notes, and more.

Note that these resources largely explore the history of preserving a historical site, rather than the importance of the site itself. This is the history of making history public. The documents are most likely to be of use in the later grades, as they lean towards official language. However, there are also images such as floor plans and photographs within documents which may be of use when introducing a park into your discussions.

The Center on Congress, led by former U.S. Representative Lee Hamilton, exists to help the public better understand the role of Congress and the public's relationship to it. Their audience includes the general public, teachers, and journalists.

Your first thought as an educator may be to click on Teacher Resources. However, this section is more of a gateway to content in Learn About Congress than a section unto itself. That said, Classroom Resources does include a tool for paring down the site's educational materials to the appropriate grade level and topic, as well as best practices videos of lessons in action.

Learning About Congress has the widest variety of content useful to the K-12 educator. Resources include approximately 8 interactive modules, more than 20 short animated videos, a collection of live-action video clips of "insider views," more than 30 brief audio presentations on issues ranging from disaster relief to bilingual education, and a variety of relevant reading material. The spoken narration on the interactive modules tends to be dry, and would more than likely only be of use in the higher grades. However, the animated videos are enthusiastically narrated, making them more appropriate for a wider range of viewers. A free Citizen's Guide helps to connect daily life to the actions of Congress. The guide is not unlike a textbook in terms of language and graphic design. As such, its format should be readily accessible and familiar to the average student.

Depending on your computer access and comfort with online activities, you may also be interested in the Virtual Congress where your students can create members of Congress, move their avatars through digital recreations of key locations, and participate in a "multi-player" setting proposing legislation. Another option is Teaching with Primary Sources, a joint effort between the Center on Congress and the Library of Congress, providing separate entry points for teachers and students. These offerings require free registration.

Other items of interest on the site include results of public and political scientists' surveys on Congress' function, beginning in 2002; a blog concerning topics relevant to current Congressional issues; and Congressional FAQs. Teachers can also apply for the American Civic Education Teacher Awards.
