For Us the Living is a resource for teachers that engages high school students through online primary-source based learning modules. Produced for the National Cemetery Administration's Veterans Legacy Program, this site tells stories of men and women buried in Alexandria National Cemetery, and helps students connect these stories to larger themes in American history. Primary sources used include photographs, maps, legislation, diaries, letters, and video interviews with scholars.

The site offers five modules for teachers to choose from, the first of which serves as an introduction to the cemetery's history. The other four cover topics such as: African American soldiers and a Civil War era protest for equal rights, the manhunt for John Wilkes Booth after Lincoln’s assassination, commemoration of Confederates during Reconstruction, and recognition of women for their military service. Most of the modules focus on the cemetery’s early history (founded in 1862) although two modules reach into the post-war era. Each module is presented as a mystery to solve, a question to answer, or a puzzle to unravel. Students must use historical and critical thinking skills to  uncover each story. Each module ends with two optional digital activities, a historical inquiry assignment and a service-learning project, related to the module theme.

Teachers should first visit the “Teach” section which allows them to preview each module (including its primary sources, questions and activities), learn how to get started, and see how the site’s modules connect with curriculum standards. In order to access the modules for classroom use, teachers do have to create their own account, but the sign up process is fast, easy, and best of all, free! The account allows teachers to set up multiple classes, choose specific module(s) for each class, assign due dates, and view student submissions.

The Digital Public Library of America (DPLA) serves as a portal to the digital collections of more then 40 state, regional, and online-only libraries, museums, archives, and other cultural institutions. Created to strengthen access to public resources and to "create novel environments for learning, tools for discovery, and engaging apps," the DPLA is an invaluable first stop for teachers and students looking for primary sources, particularly regional history sources.

Visitors to the website can search the more than 4,500,000 objects in the collections of participating institutions using keywords, returning results they can filter by format, owning institution, partner, date, language, location, and subject. Clicking on an object brings up detailed metadata, including creator, date of creation, and a description of the object, as well as a link to its original location online. Visitors who create a free account can save their search results, make them private or public, and share them via Facebook, Twitter, or Google+.

Visitors can also browse objects on a map or timeline—a fantastic way to prompt thinking about how primary sources are located in time and space. The timeline stretches from 1000 BCE to the present. (Note that zooming into the map returns finer results.) In addition, more than eight virtual exhibits demonstrate how DPLA sources can be curated to tell stories about themes and events.

The DPLA's API (application programming interface) allows visitors with the know-how to create apps drawing on the DPLA's collections. An eclectic set of more than 10 apps lets visitors browse DPLA's search results as a "river of images," discover primary sources related to their Zotero bibliographies, and more.

A fantastic starting point for anyone looking for primary sources, teachers can feel confident pointing students towards the DPLA to begin research projects or turning to the DPLA themselves to find resources to support lesson plans.

The stated purpose of this website is to provide an overview of World War I. This it does effectively through hundreds of essays, 3,100 encyclopedic entries, 618 biographies, 318 resources on the war's major diplomatic and military events, and a timeline. Primary documents include over 100 diaries and firsthand accounts of soldiers and politicians, 3,900 photographs, 651 propaganda posters, and 155 audio files of songs and speeches. Documents include treaties, reports, correspondence, memoirs, speeches, dispatches, and accounts of battles and sieges.

The site also provides 95 essays on literary figures who wrote about the war. While admittedly a work-in-progress, the site offers much material on the leaders who engaged their countries in war and on the experiences of ordinary soldiers who fought the battles.

Emma Goldman (1869–1940) was a major figure in the radical and feminist movements in the United States prior to her deportation in 1919. This collection of primary resources includes selections from four books by Goldman as well as 18 published essays and pamphlets, four speeches, 49 letters, and five newspaper accounts of Goldman's activities.

There are also nearly 40 photographs, illustrations, and facsimiles of documents. Additional items include two biographical exhibitions, selections from a published guide of documentary sources, and four sample documents from the book edition of her papers. A curriculum for students is designed to aid the study of freedom of expression, women's rights, anti-militarism, and social change. The site offers essays on the project's history and bibliographic references as well as links to other websites.

The more than 3,500 full-text documents available on this website address the legal, economic, political, diplomatic, and government history of the U.S. Documents are divided into five time periods—pre-18th, 18th, 19th, 20th, and 21st centuries—and include treaties, presidential papers and addresses, and colonial charters, as well as state and federal constitutional and legal documents.

The materials are categorized into 64 document collections as well, such as American Revolution, Federalist Papers, slavery, Native Americans, Confederate States of America, World War II, Cold War, Indochina, Soviet-American diplomacy, and September 11, 2001. By clicking "What's New," the latest digitized documents become available. Material also can be accessed through an alphabetical list of 350 more specific categories, keyword searching, and advanced searching. Most of these documents are directly related to American history, but the site includes some materials on European and modern diplomatic history.

This ongoing project was designed to present materials on the historical experiences of those with disabilities. The website currently presents nearly 800 documents and more than 930 still images dating from the late 18th century to the present.

Subjects are organized according to categories of advocacy, types of disability, government, institutions, medicine, organizations, private life, public life, and personal names. Documents include articles, poems, pamphlets, speeches, letters, book excerpts, and editorials.

Of special interest are documents from the Roosevelt Warm Springs Institute for Rehabilitation Archives, including the Polio Chronicle, a journal published by patients at Warm Springs, Georgia, from 1931 to 1934. Images include photographs, paintings, postcards, lithographs, children's book illustrations, and 19th-century family photographs, as well as postcard views of institutions, beggars, charity events, and types of wheelchairs.

This website provides free access to a variety of visual materials and "seeks to illustrate the unique role of visual images in American history." Clio is an educational organization developing American history projects with appeal to a wide audience, including students, educators, and researchers. This site aims to not only provide access to a variety of visual historical materials, such as photographs, illustrations, and material objects (namely quilts), but also "to promote visual literacy by exploring the variety of ways that images enhance our understanding of the past and challenge us to hone our interpretive skills."

The website is organized into three main sections. The first, "Visualizing America," includes two collections of modules, titled "Picturing the Past: Illustrated Histories and the American Imagination, 1840–1900," and "Quilts as Visual History." A second section, ”Photography Exhibits," includes three photography collections: one focusing on the work of Frances Benjamin Johnston, another on the work of the Allen Sisters (Mary and Frances Allen), and the Peter Palmquist Gallery. A third section, "Creating History," examines the figure of Lowell Thomas, who became one of America's best known journalists, as well as the media version and reality of Lawrence of Arabia.

An additional section concerning women's history and lives in the 21st century and second half of the 20th century is planned for 2013.

A valuable website to students and researchers alike, it suffers only slightly from a lack of search capabilities.
