FIELD DEFINITION AND SCOPE
Explanatory text and the classification number referred to that are
required when see also relationships exist between classification numbers that
cannot be adequately conveyed by one or more simple cross references generated from
field 553 (Valid Number Tracing).
This field guides the user to related topics classed in other valid classification
numbers. A Complex See Also Reference is appropriate only in valid or partially valid
classification number records (as indicated in 008/08 (Classification validity), code a,
b, or c).
A cross reference display may be constructed from the 153 and 353 fields of the record.
Field 153 (Classification Number) contains the classification number or span referred
from and field 353 contains the classification number or span referred to. When several
reference notes are associated with a classification number, each note may be recorded
in a separate field or they may be combined and recorded in a single field.
GUIDELINES FOR APPLYING CONTENT DESIGNATORS
■ INDICATORS
- Both indicator positions are undefined; each contains a blank (#).
■ SUBFIELD CODES
$a - Classification number referred to-single number or beginning number of span Single classification number or the beginning number of a classification number
span to which reference is made from the classification number(s) in field 153 of
the record.

$c - Classification number referred to-ending number of span Element of the ending number of a classification number span to which reference is
made from the classification number(s) in field 153 of the record. The element may
consist of the whole classification number or a part of the classification
number.

$y - Table sequence number for internal subarrangement or add table Sequence number or other identifier for an internal classification subarrangement
or add table. If the first or only add table found at a classification number is
the number 1, succeeding integers are used for any following add tables found
at that number.
$z - Table identification Identification of the table to which a classification number recorded in field 353
belongs, if the classification number is part of a table. The identification of
the table by which a classification number or span is further sub-arranged is
contained in field 762 (Table Identification). For a classification number span,
subfield $z is given only once, before the first number. Subfield
$z is input before the first element of the classification number in
the first subfield $a.

INPUT CONVENTIONS
Applicable input conventions - Input conventions described in the X53 Classification Numbers-General
Information section are also applicable to this field.
Display constants - Display constants for a reference instruction phrase may be system generated on the
basis of the field tag. However, because several types of standard wording may be used
for see references, it may not be desirable to use display constants. In cases where
display constants are not used, all terms to be displayed are recorded explicitly in
field 353 subfield $i (Explanatory text).
SCHEME-SPECIFIC CONVENTIONS
Library of Congress Classification - For
LCC, field 353 is used for the following situations:
- If more than three numbers are referred to, which would require more than three
tracings in three separate records
- If a synthesized number is referred to and it is not desirable to create a
separate record for it
- If a span of numbers or whole subclasses are referred to for which no separate
classification record exists
- For a general reference note that does not contain a specific classification
number or that includes a specific number or numbers only as illustrative
examples.
Dewey Decimal Classification - This field is not likely to be used frequently in the Dewey Decimal
Classification except when it is desirable to provide both complex reference fields
(253, 353) and tracing fields (453, 553). Since the majority of see also references can
be accommodated in a simple see also tracing field (353), the example shown is only
intended to illustrate the coding of data elements, not to show instances of actual
use.
