Immigration Subject Headings

The rules on this page are a draft until reviewed by SCRAP and CAMM. The rules have already been approved. Please send any feedback to help@ccslib.org.

In alignment with the SAC Working Group recommendation of 2016, CCS has decided to replace all illegal alien related subject headings with the recommendations by SAC as of June 7, 2021. These headings will be in 650 fields with a second indicator of 0 until the Library of Congress updates the LCSH terms. The authority records have been updated to reflect the change. When cataloging works on these topics, please update the records by replacing the LSCH terms with the equivalent terms in the chart below. If you do not replace the terms, the Data Services Librarian will regularly query the database for records to correct.
