010 Library of Congress Control Number (NR) (Variable Data Fields)
Field Definition and Scope:

In separate holdings records distributed by the Library of Congress, the control number for the related LC bibliographic record is contained in field 004 (Control Number for Related Bibliographic Record).

(Field 010 is an agency-assigned field; it is used only for an LC bibliographic record control number.)
