When your patrons ask for published immigration, passenger and naturalization records of individuals who came to the U.S. and Canada between the 16th and mid-20th centuries, direct them to this comprehensive resource. Here they'll find everything needed for fruitful genealogical research. Main entries in Passenger And Immigration Lists Index provide information such as name and age of immigrant; year and place of arrival, naturalization, or other record indicating that the person indexed was an immigrant; code indicating the source indexed and the page number in the source that contains the record; and the names of all listed family members together with their age and relationship to the main entry. Thirty annual supplements (published 1982-2005) have increased the number of citations to more than four million names indexed.
