In this unit, students will trace the development of sectionalism in the United States as it was driven by the growing dependence upon, and defense of, black slavery in the southern states.

In August 1964, a small military engagement off the coast of North Vietnam helped escalate the involvement of the United States in Vietnam; the Vietnam War would become the longest military engagement in American history prior to the Iraq and Afghanistan wars.

For many Americans, their fondest memories revolve around a library card. From searching through the stacks, to getting a return date stamped on the back of a new favorite book, libraries are a quintessential part of how Americans learn and engage with their local communities. Since this country’s founding, public libraries have received broad and consistent popular support for their democratic missions and services. The ability to access free information has become a core ideal of what it means to be an American citizen, despite periods of historic inequality. Libraries help make this access possible by placing public benefit at the center of their work and continually adapting their strategies to meet changing public needs over time. This exhibition tells the story of the American public library system, its community impact, and the librarians who made it possible—from the founding of the first US libraries through the first one hundred years of service. This exhibition was created as part of the DPLA’s Public Library Partnerships Project in collaboration with partners and participants from Digital Commonwealth, Digital Library of Georgia, Minnesota Digital Library, Montana Memory Project, and Mountain West Digital Library.

In this activity, students read two primary documents from the early 1800s: a journal entry from the Lewis and Clark expedition and a Lakota Indian "winter count" calendar. Using an analysis worksheet, students identify key ideas and details from the documents, while also examining the craft and structure of each document. They draw upon both the content and form of the documents to make inferences about the respective cultures of Euro-Americans and Native Americans in the early 1800s.

In this activity, students work with quantitative data (charts, graphs, and tables) from the 1910 census and the 1911 Dillingham Commission Report to understand the lives of immigrants in the Ellis Island era. The activity includes an option designed for middle school and high school students, as well as a suggested strategy for elementary students. After studying the data, students write a narrative in the voice of an immigrant in 1910, incorporating the information gleaned.

In this activity students analyze a political cartoon, a presidential speech and an anti-immigration pamphlet from the early 20th century. After analyzing the documents, students write about why the United States passed immigration quotas in the 1920s.

In this activity students read three letters written by African-American soldiers during the Civil War to determine why black soldiers felt compelled to join the Union Army.

For many Americans today, snapping a photo is as easy as pulling out a smartphone. However, that digital photo is the result of decades of experimentation and development, from first forays into bulky and difficult-to-use professional cameras to instant-photo Polaroids. Since the advent and eventual commercialization of photography throughout the nineteenth century, cameras have continuously redefined the American public’s conception of how images and history can be captured and shared. Looking to the early cameras of the 1800s to today’s cell phones and social networking apps, this exhibition explores how the personal camera has shaped American consciousness and culture over the course of its development. This exhibition was created as part of the DPLA’s Digital Curation Program by the following students as part of Dr. Joan E. Beaudoin's course "Metadata in Theory and Practice" in the School of Library and Information Science at Wayne State University: Ellen Tisdale, Rachel Baron Singer, Amanda Seppala, Michell Geysbeek, and Jay Purrazzo.

December 2013 marks the 80th anniversary of the end of Prohibition, the period between 1920 – 1933 when the manufacture, transport and sale of intoxicating liquors was illegal in the United States. The 18th Amendment to the Constitution, ratified in 1919, was the crowning achievement of a temperance movement that had been building in this country since the late 1700s. Alcohol consumption had peaked to a high of about 7 gallons per person in the early 1800s (compared to less than 3 gallons today), with recognized health and societal consequences. But the new laws were difficult to enforce, due to general unpopularity and the profits that could be made through circumventing the law. Demand for alcohol remained high, and organized crime and corruption flourished. Loopholes and exemptions also allowed home wine production, and prescriptions for medical alcohol rose dramatically. Enforcement difficulties, popular resistance, and economic pressures associated with the Great Depression all contributed to efforts to repeal Prohibition. In 1933, the 21st Amendment ended national prohibition and returned responsibility for alcohol regulation to the states. The Kentucky Digital Library and DPLA would like to thank the contributing institutions for providing the unique content and metadata featured in Indomitable Spirits: Prohibition in the United States.

In this activity, students read a series of primary source documents, including the 1872 print "American Progress," that depict the social, political and cultural conflicts between settlers and Native Americans during the 19th century. Then, working in small groups, students will consider the events from the perspective of Native Americans, and create an illustration to counter George A. Crofutt's famous print of "American Progress" moving across the Great Plains.

Students learn how civil rights activists including the Freedom Riders, state and local officials in the South, and the Administration of President Kennedy come into conflict during the early 1960s.
