CHANGE OF HEADING 1XX: change to:____________________________________________________________

Indicate the new form of heading in this area.

NOTE: Because changing the 1XX field of a subject heading may involve significant work on maintenance of the bibliographic and authority files both at the Library of Congress, and in other libraries, a cataloger should consider the impact of such a change and be judicious in recommending one. Changing the 1XX field of a subject heading means also changing all occurrences of that subject heading in other authority records (e.g., use as BT references, appearance in scope notes, use with subdivisions, etc.). Changing the 1XX field of a subject heading must be supported by adequate, appropriate authority research demonstrating clear preference for the proposed form. Cite references in 670s. When in doubt, contact the Cooperative Cataloging Team at: saco@loc.gov.

Changes to Cross-References 4XX: add:_____________ 4XX: change:__________ 4XX: delete:__________
