The massive influx of immigrants to the United States in the late 19th and early 20th centuries shaped American society both at the time and indefinitely. The following primary source set explores materials organized for the Collaborative for Educational Services and by the Library of Congress. The Library of Congress has crafted a vast number of primary source sets, interactive presentations, and collections to showcase the tremendous volume of materials on the subject.
Additional sets from CES explore Puerto Rico and Cape Verdean immigration. In addition, notable resources at the end of the set draw focus to historical immigration documents at the National Archives, Ellis Island, and the Population Reference Bureau.
