Thesaurus for Graphic Materials I (TGM): An Introduction

III.A. Nationality Subdivisions

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."
