A facet indicator for nationality is added selectively to terms for certain occupations, activities, and objects. The facet is used to indicate a national association, particularly in cases where the subject either operates on behalf of a nation or where its occurrence outside its nation of origin is likely to be of interest. Nationality terms are drawn, wherever possible, from LCSH.
Example: [Thesaurus] Soldiers--[nationality]
[Indexing string] Soldiers--Italian
[Thesaurus] Automobiles--[nationality]
[Indexing string] Automobiles--Japanese
(Note: Because of P&P's extensive American Civil War holdings, the nationality facet has been added to a number of headings in order to be able to append the "nationality" designation "--Confederate" or "--Union.")
MARC coding: Nationality subdivisions are assigned subfield code "x."
