This book covers immigrants in the area of origin, on the journey, and at the destination. The work is divided into four sections - bibliography, manuscript collections, government manuscripts and publications, and a statistical overview. It is based on a review of all extant books and journal articles (including theses and dissertations) and a ten-year US wide search for manuscript collections held by research libraries, archdiocesan centres, and other depositories; for government manuscripts and published documents; and for statistical sources at origin and destination.
