For researchers, instructors, and others interested in the history of U.S. immigration, the Digital Public Library of America offers this rich collection of digitized resources (including photographs, documents, letters, newspaper clippings, and much more) related to the topic. This collection was curated by Andrea Ledesma and includes dozens of items from heritage and memory institutions, including the University of Minnesota's Immigration History Research Center, the National Museum of American History, the New York Public Library, the Los Angeles Public Library, and many others. Visitors can browse these items by eight thematic categories. For instance, in the Coming to America section, visitors will find a number of items that document immigrants' experiences and obstacles upon arrival to the US. These items include a 1847 book by Fredrich Pauer that "[describes] Texas and the United States for people interested in emigrating from Germany" and an oral history interview with Mustafa Jumale, who, along with his family, immigrated to the U.S. as a small child in the early 1990s due to civil war in Somalia. Other categories include Becoming an American, Discrimination and Reform, and Immigration Since 1965.
