Each week we scour the web for interesting and historic documents that catch our eye, make us think or simply make us laugh.

Photo Credit: Library of Congress, Frank and Frances Carpenter Collection. Date: between ca. 1890 and 1923. Photo Description (via World Digital Library): “This photograph of newly arrived immigrants in Buenos Aires, Argentina is from the Frank and Frances Carpenter Collection at the Library of Congress. Frank G. Carpenter (1855–1924) was an American writer of books on travel and world geography, whose works helped to popularize cultural anthropology and geography in the United States in the early years of the 20th century. Consisting of photographs taken and gathered by Carpenter and his daughter Frances (1890–1972) to illustrate his writings, the collection includes an estimated 16,800 photographs and 7,000 glass and film negatives. Carpenter’s Geographical Reader: South America (1899) informed readers that “Buenos Aires is by far the largest Spanish-speaking city of the world; it is more than three times the size of Madrid, the largest city of Spain. Still, most of its people are foreigners. Not more than one fifth of them were born in the country. There are more Italians than native Argentines in Buenos Aires, and at least one hundred thousand of its citizens have come here from Spain.”
