except for the absence of bibliographic subfields $u
(Affiliation), $4 (Relator code) and $6 (Linkage), the defined
indicators and subfield codes are the same as those listed in the
MARC 21 Concise Format for

. Definitions for the additional subfields defined for
some of these fields in classification data records are given
this section. Reference to the appropriate bibliographic field
where descriptions may be found are given for other subfields.
Field 753 (Index Term--Uncontrolled) is a special-use
classification data field whose subelements are described
here.
