Immigration, Relocation, and Internal Migration Within the United States

"This digital collection of historical materials from Harvard's libraries, archives, and museums documents voluntary immigration to the United States from the signing of the Constitution to the start of the Great Depression." Emphasis on 19th century.

The Immigration History Research Center & Archives holds one of the largest collections of primary source materials on immigration and the United States. Over 100,000 pages of letters, diaries, and oral histories spanning 1800-1950 have been scanned and posted to the Internet.

The American Immigration Council works to strengthen America by shaping how America thinks about and acts towards immigrants and immigration and by working toward a more fair and just immigration system that opens its doors to those in need of protection and unleashes the energy and skills that immigrants bring."
