This
field contains a code for the subject category, or facet, that is
associated with the 1XX field in an
established heading record. The
code indicates the relative position of the heading in a particular
hierarchical arrangement in the thesaurus. The UNBIS Thesaurus is
organized into 18 broad subject categories,
each of which is further divided into sub-categories.
The six-digit code represents the subject category and sub-category to
which a thesaurus term has been assigned. Since a thesaurus term may be
classified within more that one category, field 072
is repeated for
each location of the heading in the thesaurus.
Required for thesaurus headings.
The
complete list of categories is posted on the
web site.
Note: This field is used only for
thesaurus headings, not for geographical name headings.
