Thanks to the joint efforts of a student group and university librarians at Dartmouth College, Hanover, NH, with a push from the American Library Association , the Library of Congress announced on March 22 that it would remove the term "Illegal alien" from the LC Subject Heading system, replacing it with "Noncitizen" and, to describe the act of residing without authorization, "Unauthorized immigration." The heading "Illegal aliens" will become a "former heading" reference, cross-referenced with the new terminology; other headings that include the phrase will also be revised or canceled.
