The Immigration History Research Center, located in Andersen Library at the University of Minnesota, manages one of the largest archives in the world on immigrant and refugee life in North America. (The archives themselves are housed in large limestone caverns excavated into the banks of the Mississippi River.) Researchers from the U.S. and the world have used its particularly rich collections of periodicals, manuscripts, and publications on immigrants who arrived from southern and eastern Europe and from the Middle East in the years between 1880 and 1930 and on refugees and displaced persons resettled in the United States between 1945 and the mid-1990s. Users of the WorldwideWeb have access to the IHRC catalogue, to its VITRAGE collection of digitized visual materials, and to digitized documents that illustrate themes of special interest to researchers. Further information about the archives of the IHRC is accessible through its webpage (http://ihrc.umn.edu/research/). The archives are open to all researchers. Visitors are urged to contact the curatorial staff of the IHRC about their special research needs: firstname.lastname@example.org.
