The United States has a long history of activists seeking social, political, economic, and other changes to America—along with a history of other activists trying to prevent such changes. American activism covered a wide range of causes and utilized many different forms of activism. American sociopolitical activism became especially prominent during the period of societal upheaval which began during the 1950s. The African American civil rights movement led the way, soon followed by a substantial anti-war movement opposing American involvement in the Vietnam War, and later by vigorous activism involving women’s issues, gay rights, and other causes. The United States remains a land of nearly constant change, and activists play a significant role in the ongoing evolution of American democracy. It seems likely that Americans will remain enthusiastic activists in the future. This exhibition is part of the Digital Library of Georgia.

In this unit, students learn about the form and function of the human heart through lecture, research and dissection. Following the steps of the Legacy Cycle, students brainstorm, research, design and present viable solutions to various heart conditions as presented through a unit challenge. Additionally, students study how heart valves work and investigate how faulty valves can be replaced with new ones through advancements in engineering and technology. This unit demonstrates to students how and why the heart is such a powerful organ in our bodies

In the spring of 1918, the United States was embroiled in World War I, fighting alongside the English, French, and Russians against the Central Powers of Germany and Austria-Hungary. In total, 70 million men were at war on multiple fronts across Europe, Russia, the Middle East, and Northern Africa. The tide was finally turning for the Allies after a crushing offensive by German forces mere weeks earlier. Then, a fierce enemy intervened—an outbreak of influenza that would decimate entire regiments and towns, kill civilians and soldiers alike by the millions, and rapidly become a global pandemic. This disease weakened forces on both sides, changing not only the course of the war but also the economies and population stability of every affected nation. In the long term, this particular outbreak would inspire research on an unprecedented scale and lead to advances in science and medicine, forever altering our understanding of epidemiology. From the spring of 1918 to early 1919, no aspect of life remained untouched by the pandemic for Americans at home and on the front. This exhibition explores the pandemic’s impact on American life.  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: Bethany Campbell, Michelle John, Samantha Reid-Goldberg, Anne Sexton, and John Weimer.

Throughout the early twentieth century, women looked to break new ground in ways never before possible, and the sky literally became the limit. As the nation moved into the aviation age, many women saw flying as a way to break out of traditional societal roles. It gave women not just an opportunity for adventure and excitement, but a way to earn a living outside of the home that demanded respect. Aviatrix Ruth Bancroft Law described it, after defeating the cross-country distance record: "There is an indescribable feeling which one experiences in flying; it comes with no other form of sport or navigation. It takes courage and daring; one must be self-possessed, for there are moments when one's wits are tested to the full. Yet there is an exhilaration that compensates for all one's efforts." In this exhibition we explore the early history of aviation and the courageous women who took to the skies—aviatrixes who found freedom, broke new ground, and inspired generations of women along the way. This exhibition was created as part of the DPLA’s Digital Curation Program by the following students as part of Professor Debbie Rabina’s course "Information Services and Sources" in the School of Information and Library Science at Pratt Institute: Megan DeArmond, Diana Moronta, Laurin Paradise.

The stock market crash on October 29, 1929 -- known as Black Tuesday -- was the "worst economic collapse in the history of the modern industrial world." It spread from the United States to national economies across the globe. It ended a decade known for its high-spirited free-spending, called the Roaring 20s, and began almost 10 years of financial desperation that would touch nearly every citizen of the United States. The Great Depression caused bank closures and business failures and by its end, saw "more than 15 million Americans (one-quarter of the workforce)" unemployed. Herbert Hoover, president at the time, did not acknowledge the depth of the crisis and assumed that the American characteristics of individualism and self reliance would quickly bring the nation out of the disaster without a need for federal intervention. But, layoffs and financial desperation at the personal level were growing: "an empty pocket turned inside out was called a 'Hoover flag' [and] the decrepit shanty towns springing up around the country were called 'Hoovervilles'." Three years into the financial crisis, Franklin Delano Roosevelt, running on a platform of federal recovery programs called the "New Deal," easily took the presidential election of 1932.

It was approximately 40,000 years ago that mankind first donned a pair of shoes. During humanity’s long history of footwear, and an equally broad array of styles, the basic fundamentals of Western shoemaking remained mostly unchanged until the mid-nineteenth century. In the 1800s, the small state of Massachusetts revolutionized the shoemaking industry, cladding the feet of consumers nationwide in unprecedented numbers. One of America’s original colonies, Massachusetts found itself at the heart of the nation’s shoemaking industry by attracting and retaining skilled shoemakers and shoe machinery engineers. Only when the technology that Massachusetts' shoemakers invented became available beyond the state did the industry’s market expand throughout the country. Even with the spread of industrialization, Massachusetts remained the largest producer of shoes in the United States through World War I, responsible for nearly forty percent of America’s shoes and home to an equal percentage of its shoemakers. This exhibition was created as part of the DPLA’s Public Library Partnerships Project by collaborators from Digital Commonwealth. Exhibition organizer: Anna Fahey-Flynn.

Students examine an image produced by a cabinet x-ray system to determine if it is a quality bone mineral density image. They write in their journals about what they need to know to be able to make this judgment. Students learn about what bone mineral density is, how a BMD image can be obtained, and how it is related to the x-ray field. Students examine the process used to obtain a BMD image and how this process is related to mathematics, primarily through logarithmic functions. They study the relationship between logarithms and exponents, the properties of logarithms, common and natural logarithms, solving exponential equations and Beer's law.

In 1803, the United States purchased the Louisiana Territory—800,000 square miles of land in the interior of North America. Most of this land had not been previously explored or documented. President Thomas Jefferson chose Meriwether Lewis and William Clark to lead an ambitious military expedition, seeking a northwestern passage to the Pacific Ocean and to document their journey in this unknown territory. Starting in what is now Missouri, the expedition followed the Missouri River and passed through present-day Montana on its way to the Pacific. The explorers commented on the beauty of the landscape and the abundance of animals, and their descriptions attracted fur traders and others ready to take advantage of the region's abundant natural resources. The discovery of gold in 1862 brought in the first rush of people and subsequent mining forever changed the region. The mining industry demanded support in the form of towns, railroads, logging, ranching, and farming. These industries shaped Montana and the people who settled there. This exhibition explores the industries that brought settlers to Montana from the early days to the 1920s. Each industry had its own “boom and bust” cycle that impacted the residents and the future of the state. This exhibition was created as part of the DPLA’s Public Library Partnerships Project by collaborators from Montana Memory Project: Jennifer Birnel, Della Yeager, Cody Allen, Dale Alger, Caroline Campbell, Carly Delsigne, Pam Henley, Stef Johnson, Lisa Mecklenberg-Jackson, Laura Tretter, and Franky Abbott.

Boston Sports Temples celebrates the rich histories of Boston’s professional stadiums and arenas. Some, like Fenway Park, still welcome fans today. Others were demolished decades ago, leaving only hints of their former glory amid the urban landscape. This exhibition welcomes modern fans through the gates of venues both famous and forgotten: the various home fields—and courts and tracks and ice—of Boston’s most beloved franchises and hosts to a century of public events, concerts, and gatherings. Featuring historical photographs from the Boston Public Library’s extensive archives, Boston Sports Temples draws from thousands of negatives and prints dating from the early twentieth century through the 1960s. The images capture the unique character of Boston’s historic sports venues, memorable moments, and the communities of athletes, fans, and staff who have come together within their walls. Together, these vintage materials provide an invaluable window into the past and a nostalgic look back at our city, our deep sporting traditions, and generations of passionate fandom. Created by the Boston Public Library.

The Lawrence Textile Strike was a public protest mainly of immigrant workers from several countries, including Austria, Belgium, Cuba, Canada, France, England, Germany, Greece, Ireland, Italy, Lithuania, Netherlands, Norway, Poland, Portugal, Russia, Scotland, Spain, Syria, and Turkey. According to the 1910 census, 65% of mill workers (many of whom eventually struck) lived in the United States for less than 10 years; 47% for less than five years. Prompted by a wage cut, the walkout spread quickly from mill to mill across the city. Strikers defied the assumptions of conservative trade unions within the American Federation of Labor that immigrant, largely female and ethnically diverse workers could not be organized. The Lawrence strike is referred to as the “Bread and Roses” strike and “The Strike for Three Loaves." The first known source to do so was a 1916 labor anthology, The Cry for Justice: An Anthology of the Literature of Social Protest by Upton Sinclair. Prior to that, the slogan, used as the title of a 1911 poem by James Oppenheim, had been attributed to ‘Chicago Women Trade Unionists.’ It has also been attributed to socialist union organizer Rose Schneiderman. James Oppenheim claimed his seeing women strikers in Lawrence carrying a banner proclaiming “We Want Bread and Roses Too” inspired the poem, “Bread and Roses.” The poem, however, was written and published in 1911 prior to the strike. Later the poem was set to music by Caroline Kohlsaat and then by Mimi Farina. The song and slogan are now important parts of the labor movement and women’s movement worldwide. This exhibition was made in collaboration with the Lawrence History Center and the University of Massachusetts Lowell History Department.

As the United States began the most deadly conflict in its history, the American Civil War, it was also laying the groundwork for one of its greatest achievements in transportation. The First Transcontinental Railroad, approved by Congress in the midst of war, helped connect the country in ways never before possible. Americans could travel from coast to coast with speed, changing how Americans lived, traded, and communicated while disrupting ways of life practiced for centuries by Native American populations. The coast-to-coast railroad was the result of the work of thousands of Americans, many of whom were Chinese immigrant laborers who worked under discriminatory pressures and for lower wages than their Irish counterparts. These laborers braved incredibly harsh conditions to lay thousands of miles of track. That track—the work of two railroad companies competing to lay the most miles from opposite directions—came together with the famous Golden Spike at Promontory Summit in Utah on May 10, 1869. This exhibition explores the construction of the first Transcontinental Railroad and its impact on American westward expansion. This exhibition was created as part of the DPLA’s Digital Curation Program by the following students as part of Professor Krystyna Matusiak's course "Digital Libraries" in the Library and Information Science program at the University of Denver: Jenifer Fisher, Benjamin Hall, Nick Iwanicki, Cheyenne Jansdatter, Sarah McDonnell, Timothy Morris and Allan Van Hoye.

In twenty-first century American society, childhood is popularly understood as a time of innocence, learning, and play. At the end of the nineteenth century, however, children made up part of the country’s workforce, and labored on farms and in factories. When they were not working, they enjoyed great independence in leisure activities—be it in a loud city street or a peaceful country lake. Often, children were far from adult supervision. Reformers during the Progressive Er—a period of social activism and political reform across the United States between the 1890s and 1920s —took a great interest in child welfare. Through organizations and legislation, they sought to define what a happy and healthy childhood should be in the modern age. Immersion in nature was central to what the Progressives prescribed, and children’s organizations and camps offered a suitable combination of supervision and open spaces. The formula for a healthy childhood was further refined in postwar America. Children were given a distinct place in the family and home, as well as within the consumer market with the emergence of teenage culture and buying power. This exhibition was created as part of the DPLA's Public Library Partnerships Project by collaborators from the Digital Library of Georgia and Georgia's public libraries.

Students are introduced to the world of creative engineering product design. Through six activities, teams work through the steps of the engineering design process (or loop) by completing an actual design challenge presented in six steps. The project challenge is left up to the teacher or class to determine; it might be one decided by the teacher, brainstormed with the class, or the example provided (to design a prosthetic arm that can perform a mechanical function). As students begin by defining the problem, they learn to recognize the need, identify a target population, relate to the project, and identify its requirements and constraints. Then they conduct research, brainstorm alternative solutions, evaluate possible solutions, create and test prototypes, and consider issues for manufacturing. See the Unit Schedule section for a list of example design project topics.
