DEFINITION AND SCOPE
Number Building Fields provide instructions for building onto classification numbers
from sources within the schedule and tables of the scheme identified in field 084
(Classification Scheme and Edition). Such fields are highly structured, and many are
intended to assist the classifier in constructing classification numbers. The
information in these fields is not written in a form adequate for public user display.
Footnotes containing instructions that apply to several classification numbers are
converted to the appropriate 6XX or 76X field.
