After receiving the new and revised subject authority records from the Library of Congress on November 30, OCLC has been working to change the Library of Congress Subject Headings (LCSH) within WorldCat records to the new forms.  The previous heading Aliens changed to Noncitizens.  The former heading Illegal aliens became both Noncitizens and Illegal immigration.  A number of related headings also changed including (but not limited to) the following:



  *   Children of illegal aliens became both Children of noncitizens and Illegal immigration

  *   Illegal alien children became both Noncitizen children and Illegal immigration

  *   Illegal aliens in literature became both Noncitizens in literature and Illegal immigration in literature

  *   Women illegal aliens became both Women noncitizens and Illegal immigration

Altogether, OCLC has updated approximately 41,000 WorldCat records to change these headings.  In the future on a periodic basis OCLC will continue to change the older headings to the newer forms when they appear in WorldCat records.  FAST headings will be changed in a subsequent process.



For information on the process of changing LCSH, see this document<https://www.loc.gov/aba/cataloging/subject/lcsh-process.html> on the Library of Congress website.



Please pardon any duplication of this message.
