From the American Philosophical Society (APS) Library comes Americanization: Then and Now, a digital exhibition examining a 1919 pamphlet entitled "Americanization: What Is It? -- What To Do," which advocated for a particular viewpoint regarding immigrants to the United States in ways that may be both familiar and surprising. The exhibition begins by first delving into the substance and rhetoric of the pamphlet itself, which is made available to readers in its entirety, as well as the historical context surrounding its publication. Next, the exhibition provides background information on the organization behind the pamphlet, the National Security League, as well as on some of its members who were also part of the APS. Finally, readers are given a brief explanation of the project, accompanied by a list of further reading and links to other relevant digital resources. Launched in 2018, Americanization: Then and Now was conceived and written by Will Fenton, who recently earned his PhD from Fordham University and specializes in early American literature and digital humanities.
