This inquiry examines the 20th century history of migration from Mexico to the United States and recent efforts to limit the movement of people across the southern U.S. border. The inquiry takes its inspiration from a 2018 podcast episode by Malcom Gladwell titled, “General Chapman’s Last Stand.” The podcast is part of Gladwell’s Revisionist History series (http://revisionisthistory.com). In the podcast, Gladwell tells the story of General Leonard F. Chapman Jr., Commandant of the Marine Corps during the Vietnam War, who went on to serve as the Commissioner of the Immigration and Naturalization Service (INS) from 1972 to 1975. Chapman is credited with reforming the INS into a more efficient and effective agency, but Gladwell argues that Chapman’s efforts also led to an unintentional increase in unauthorized immigrants. In 1970, 760,000 Mexican immigrants, or 1.4% of Mexico’s population, lived in the U.S. By 2008, there were 12.7 million Mexican immigrants in the U.S. which amounted to 11% of all people born in Mexico; an increase of almost 800% in less than 30 years. The question of how and why this happened is the central focus of this inquiry.

Boston Sports Temples celebrates the rich histories of BostonåÕs 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 fieldsåÑand courts and tracks and iceåÑof BostonåÕs most beloved franchises and hosts to a century of public events, concerts, and gatherings. Featuring historical photographs from the Boston Public LibraryåÕs 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 BostonåÕs 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 åÒBread and RosesåÓ strike and åÒThe 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 åÔChicago Women Trade Unionists.åÕ It has also been attributed to socialist union organizer Rose Schneiderman. James Oppenheim claimed his seeing women strikers in Lawrence carrying a banner proclaiming åÒWe Want Bread and Roses TooåÓ inspired the poem, åÒBread and Roses.åÓ 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 womenåÕs 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 trackåÑthe work of two railroad companies competing to lay the most miles from opposite directionsåÑcame 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 DPLAåÕs 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 countryåÕs workforce, and labored on farms and in factories. When they were not working, they enjoyed great independence in leisure activitiesåÑbe it in a loud city street or a peaceful country lake. Often, children were far from adult supervision. Reformers during the Progressive EråÑa period of social activism and political reform across the United States between the 1890s and 1920s åÑtook 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 childrenåÕs 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.

The United States experienced extensive economic and geographical expansion during the 1840s, as the spirit of Manifest Destiny drove Americans west across the North American continent to exert their influence over new places and peoples. Influenced by this expansionary philosophy, political leaders sought to expand American trade relationships worldwide. One of the first targets of this campaign was to open diplomatic and trade relations with isolationist Japan, which had been closed to western traders for centuries. In 1852, President Millard Fillmore ordered Commodore Matthew C. Perry to lead an expedition to secure Japanese trade and access to Japan‰Ûªs ports for American ships.
