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.

Produced as a companion to a PBS documentary, this site explores the history of Las Vegas through interviews, essays, and primary documents. "The Film and More" offers a film synopsis, a program transcript, and six primary documents on Las Vegas. These include a 1943 Time article on lenient divorce laws in Nevada as a tourist attraction and a newspaper report of an NAACP protest. "Special Features" offers seven presentations that include an interview with noted Las Vegas historian Hal Rothman, an exploration of the Federal government's public relations campaign on nuclear testing in the 1950s, and an essay on Las Vegas architecture. "People and Events" offers 14 essays on the people of Las Vegas and three essays on Las Vegas history.

An interactive map allows the visitor to survey the Las Vegas area and examine its development, and a timeline from 1829 to the present charts the growth of Las Vegas from a small railroad town to the present-day resort and gaming metropolis that is the most visited place in the world. A teachers' guide contains two suggested lessons each on history, economics, civics, and geography. The site also has 11 links to related websites and a bibliography of 55 books. The only search capability is a link to a search of all PBS sites.

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 private organization behind this website is in the process of digitizing millions of records from the Lincoln Administration (March 4, 1861, through April 15, 1865), drawing from collections at the National Archives; the State Treasury, Justice, and War Departments; and other federal offices and agencies.

These records include pardon case files, applications for Federal jobs, the papers of Generals Ambrose Burnside and Henry Halleck, records on the capture of Jefferson Davis and the John Surratt trial, and numerous telegrams and letters about all aspects of Presidential business, as well as maps, photographs, and newspaper articles.

Though the majority of these records are accessible by subscription only ($150/year for individuals, more for school districts and libraries), a few are freely available at the website: thumbnails of 35 photographs (most available in higher quality elsewhere), and roughly 50 political cartoons (too small to read).

More useful for the non-subscriber is the inclusion of 100-200 word descriptions of many of the newspaper publications included in the archive, as well as video footage of several scholarly conferences and presentations about Lincoln.

An interactive timeline of Lincoln's entire life is also included, interspersed with video footage of scholars discussing important events, as well as staged audio recordings of several of Lincoln's letters and speeches, such as a letter he wrote to Mary Owens in 1837 before she broke off their courtship.

For teachers, the website presents a list of 20 links to outside lesson plans covering many themes in Lincoln's life and Presidency.

Internment experiences of Americans and Canadians of Japanese heritage in the Northwest during World War II are documented in this site, which features an exhibit that "tells the story of Seattle's Japanese American community in the spring and summer of 1942 and their four month sojourn at the Puyallup Assembly Center known as 'Camp Harmony.'" The internment camp section furnishes nearly 150 primary documents--including 12 issues of the "Camp Harmony Newsletter," 16 government documents, ten letters, 39 photographs, 24 drawings, a scrapbook, 20 newspaper clippings, and a 7,500-word chapter from the book Nisei Daughter that describes camp life. The site also provides archival guides and inventories for 21 University of Washington Library manuscript holdings relating to the internment and for 21 related collections; a 46-title bibliography for further reading; and additional information and documents related to Japanese Canadian internment. Valuable for those studying the wartime experiences and culture of interned Japanese Americans.

This website explores the vaccination process from 900 CE to the present day. Tracing humanity's earliest known observations about disease transmission and immunity up to modern vaccination programs, the website includes articles, primary sources, and interactive activities.

Most attractive to educators will be the "Gallery" section. Browse more than 550 primary sources related to disease and vaccination, including pamphlets, photographs, artifacts, and more, as well as 90 videos. For easier browsing, filter the sources by topic, media type, or time period.

History teachers will also appreciate the "Activities" section. Seven interactive diagrams illustrate scientific and historical concepts, including herd immunity, how vaccinations work and how they are made, and changes in required vaccines over time. "Pioneer Breakthroughs," an interactive quiz, tests players' knowledge of vaccine-related discoveries, and "The Scientific Method" walks players through the steps in identifying the source of a disease outbreak and containing it. "Illsville," an online game, challenges players to keep the population of a town healthy from 1600 through the present day.

The site also includes an interactive timeline featuring images and short synopses of events from 900 CE to the present. View all of the events, or filter them by topic.

A database of essays in "Articles" covers more than 50 topics in the categories "Vaccine Science," "History and Society," "Vaccine Information," "Vaccine-preventable Diseases," and "Common Questions."

Note the four lesson plans in the "Educators" section. Spanish-language versions of site content are available as well.

This archive offers a collection of more than 900,000 photographs, maps, letters, documents, books, artifacts, and other items relating to all aspects of Texas history, from prehistory through the 20th century. Subjects include agriculture, arts and crafts, education, immigration, military and war, places, science and technology, sports and recreation, architecture, business and economics, government and law, literature, people, religion, social life and customs, and the Texas landscape and nature. Some subjects include sub-categories. For instance, social life and customs, with 694 items, includes 13 sub-categories, such as clothing, families, food and cooking, homes, slavery, and travel. The visitor can also search the collection by keyword.

Resources for educators include seven "primary source adventures," divided into 4th- and 7th-grade levels, with lesson plans, preparatory resources, student worksheets, and PowerPoint slideshows. Subjects of the lessons include Cabeza de Vaca, Hood's Texas Brigade in the Civil War, life in the Civilian Conservation Corps, the journey of Coronado, the Mier Expedition, runaway slaves, the Shelby County Regulator Moderator war, and a comparison of Wichita and Comanche village life. This website offers useful resources for both researching and teaching the history of Texas.

This massive mega-website presents thousands of documents and images related to Missouri's social, political, and economic history, linking to collections housed at universities, libraries, and heritage sites across the state. These resources are organized both into archival collections (by topic and source type) and virtual exhibits.

Archival collections include maps, municipal records, government and political records, newspapers, photographs and images, books and diaries, as well as topical collections on agriculture, medicine, women, business, exploration and settlement, art and popular culture, and family, rendering the website's resources as useful for genealogists as for those interested in history.

Exhibits encompass a diverse range of subjects, and include topics of relevance to Missouri history (Miss Carrie Watkins's cookbook from the mid-19th century, several exhibits on life at the University of Missouri and Washington University, Truman's Whistle Stop campaign), and topics outside of Missouri (the body in Medieval manuscripts, Roman imperial coins, propaganda posters from World War II, and drawings documenting dinosaur discovery before the mid-20th century).

Teachers will be especially interested in the large Education section, which includes curricular resources on topics such as African Americans in Missouri, Lewis and Clark's Expedition, Missouri State Fairs, and the history of dueling.

Post-Civil-War industrialization and urbanization put new stresses on American law and society. Criminal records reveal the circumstances where social strain boiled over into violence and unrest. Using this website, visitors can search the complete Chicago Police Department Homicide Record Index from 1870 to 1930, detailing more than 11,000 homicides, and read and watch accompanying contextual material that explores tensions between laborers, industry leaders, political ideologies, social reformers, organized crime, and more.

The core of the site is the "Interactive Database." Here, visitors can search cases using keyword, case number, date, circumstances (accident, manslaughter, homicide, number of victims, number of defendants, method of killing, involvement of alcohol), details about the victim and defendant (age, gender, race, occupation), victim/defendant relationship, and legal outcome. Searches return one-line case summaries including the date, names of people involved, case number, a description of the crime, and legal outcome. Clicking on a result brings up details on the particular crime: time, location, type of death/homicide and details of homicide, details on the victim(s) and defendant(s), police involvement, and legal outcome.

Contextualizing primary and secondary sources frame this bare-bones information. A timeline features a summary of one major event and up to five photographs for every year. "Historical Context" currently offers a second timeline highlighting links to up to 17 notable cases for each year and a section on children's lives in the city, with nine newspaper articles on child labor and obituaries for activist Florence Kelley and lawyer Levy Mayer. (Sections on labor and reform movements and people and events did not work at the time of this review.) In "Legal Content," visitors can read short essays on topics related to Chicago criminal and social history, including capital punishment, anti-corruption campaigns, the Chicago Police Department, judges, lawyers, criminology, prostitution, gambling, murder-suicides, and accidents. Each essay links to related cases and onsite and off-site documents. "Legal Content" also hosts 16 downloadable acts and statutes under "The Laws."

"Crimes of the Century" organizes links to related cases under 23 topics, including the 1919 Chicago race riot and the Haymarket Affair. "Publications," the most valuable part of the site for teachers looking for primary sources, archives the full text of 15 primary and secondary documents related to Chicago crime and social change. Here users can download in PDF form modern studies on the death penalty, crime and policing in Chicago, and the Haymarket Affair, or download primary sources such as law codes and crime reports, the Hull House Maps and Papers, Chicago Daily News articles exposing graft and corruption, 19th-century studies of Chicago's homeless, and contemporary commentary on the Haymarket Affair. Finally, visitors can watch 18 interviews with present-day professors, judges, and lawyers in "Videos."

Though difficult to navigate, this site has rich resources to help students and teachers explore the challenges of change at the turn of the century.
