Immigration to the United States website now available

Harvard University has created "Immigration to the United States, 1789-1930"
http://ocp.hul.harvard.edu/immigration/
"...a web-based collection of selected historical materials from Harvard's libraries, archives, and museums that documents voluntary immigration to the US from the signing of the Constitution to the onset of the Great Depression...Concentrating heavily on the 19th century, Immigration to the United States, 1789-1930, includes approximately 1,800 books and pamphlets as well as 6,000 photographs, 200 maps, and 13,000 pages from manuscript and archival collections. By incorporating diaries, biographies, and other writings capturing diverse experiences, the collected material provides a window into the lives of ordinary immigrants...For example:
Images from Harvard's Social Museum, which was established in 1903 by Harvard professor Francis Greenwood Peabody, illustrate "problems of the social order" related to the rapid influx of immigrants.
Original manuscript and archival materials—ranging from records of the Immigration Restriction League to the papers of New Jersey librarian Jane Maud Campbell (1869-1947)—document the plight of newly arrived immigrants..."
