ENUMERATION AND CHRONOLOGY FIELDS--GENERAL INFORMATION
Fields 863-865 contain a description of the holdings of a bibliographic item in the
collections of the reporting organization.
The captions that identify the enumeration and
chronology levels and the codes that define the publication pattern of the holdings are contained
in the Captions and Pattern fields (853-855) that are linked to the 863-865 fields by a number
in subfield $8 (Field link and sequence number).
A general description of the four types of holdings data fields and their relationship to each other is given in the Holdings Data--General Information section. The specific data elements that are required for the compression or expansion of enumeration and chronology data by computer algorithm is given in the Captions and Pattern Fields--General Information section. A description of compressibility and expandability is given in the Holdings Data--General Information section.
Indicators
- First - Field encoding level
Indicates the ANSI Z39.44 or ANSI/NISO Z39.71 level of specificity contained in the field.- # - No information provided
- 3 - Holdings level 3
[863/864]
Indicates that the field contains summary enumeration and chronology information (that is, only at the first level of enumeration and chronology) for a basic bibliographic unit (field 863) or supplementary material (field 864).
- 4 - Holdings level 4
Indicates that the field contains detailed enumeration and chronology information (that is, the first and all subsequent levels of enumeration and chronology).
- 5 - Holdings level 4 with piece designation
Indicates that the field contains detailed enumeration and chronology information and an identifying number for the physical piece in subfield $p (Piece designation).
- Second - Form of holdings
Indicates whether the enumeration and chronology is expressed in a compressed or uncompressed (itemized) form and whether this field or a linked Textual Holdings field should be used for display purposes.- # - No information provided
- 0 - Compressed [863/864]
- 1 - Uncompressed
- 2 - Compressed, use textual
display
[863/864]
Display should be generated from the linked Textual Holdings field.
- 3 - Uncompressed, use textual
display
Display should be generated from the linked Textual Holdings field.
- 4 - Item(s) not published
[863/864]
Parts described in the field are unpublished.
Subfield Codes
- $a-$h - Enumeration
The levels of enumeration that either appear on an item or that are used by the reporting organization to record the receipt of an item. These enumeration subfields are correlated with the enumeration caption subfields $a-$h in the Captions and Pattern fields (853-855) linked to the 863-865 field, although the same subfields need not always be present. Full correlation of the enumeration level and the caption subfields $a-$h in linked 853-855/863-865 fields is not required when captions are not desired for displaying the holdings statement. Full correlation is required when compression or expansion of the field 863 or 864 enumeration by computer algorithm is desired. If there is no enumeration on the item for some level, enumeration may be invented and enclosed in brackets ([ ]).
When alternative numbering schemes are applicable to an item, subfields $g and $h contain the alternative enumeration. If more than two levels of alternative enumeration are required, a Textual Holdings field (866-868) is used.
When only chronology is used on an item (that is, the item carries no enumeration), the chronology is contained in the relevant enumeration subfield ($a-$h) instead of the chronology subfields ($i-$m).
- $a - First level of enumeration (NR)
- $b - Second level of enumeration (NR)
- $c - Third level of enumeration (NR)
- $d - Fourth level of enumeration (NR)
- $e - Fifth level of enumeration (NR)
- $f - Sixth level of enumeration (NR)
- $g - Alternative numbering scheme, first level of enumeration (NR)
- $h - Alternative numbering scheme, second level of enumeration (NR)
- $i-$m - Chronology
The hierarchical levels of chronology that either appear on an item or that are used by reporting organization to record the receipt of an item. These chronology subfields are correlated with subfields $i-$m in the Captions and Pattern field (853-855) linked to the 863-865 field, although the same subfields need not always be present. Full correlation of the chronology level and the caption subfields $i-$m in linked 853-855/863-865 fields is not required when captions are not desired for displaying the holdings statement. Full correlation is required when compression or expansion of the field 863 or 864 chronology by computer algorithm is desired. If an applicable chronology level is lacking on the item, chronology may be invented and enclosed in brackets ([ ]).
Months and seasons may be expressed either in natural language or by the following codes:- Month:
- 01-12 - Month
- Season:
- 21 - Spring
- 22 - Summer
- 23 - Autumn
- 24 - Winter
A month code of less than two digits is right justified and the unused position contains a zero.
When an alternative chronology scheme is applicable to an item, subfield $m contains the alternative chronology. If more than one level of alternative chronology is required, a Textual Holdings field (866-868) is used.
When only chronology is used on an item (that is, the item carries no enumeration), the chronology is contained in the relevant enumeration subfield ($a-$h) instead of the chronology subfields ($i-$m).
- $i - First level of chronology (NR)
- $j - Second level of chronology (NR)
- $k - Third level of chronology (NR)
- $l - Fourth level of chronology (NR)
- $m - Alternative numbering scheme, chronology (NR)
- $n - Converted Gregorian year
(NR)
The Gregorian-calendar conversion of a year that is recorded in a non-Gregorian scheme in a chronology-level subfield ($i-$m). - $o - Title of supplementary material
(NR) [864]
The title of supplementary material (for example, Annual buyer's guide) in field 864. When used, subfield $o immediately follows the enumeration subfield to which it applies. If the title of supplementary material is the same as the caption contained in field 854, subfield $o (Type of supplementary material), the title is not contained in the 864 field. - $o - Title of index
(NR) [865]
The title of an index (for example, Subject index) in field 865. When used, subfield $o immediately follows the enumeration subfield to which it applies. If the title of an index is the same as the caption contained in field 855, subfield $o (Type of index), the title is not contained in the 865 field. - $p - Piece designation
(NR)
An identification of a piece. The designation may be an identification number such as a bar code number or an accession number. The piece designation may be preceded by an uppercase B or U to specify whether the piece is bound or unbound. When no piece designation exists, a double slash (//) may be recorded in subfield $p to signify that the holdings relate to a piece.
When the piece designation applies to the entire holdings statement, it is recorded in subfield $p (Piece designation) of field 852 (Location). When the piece designation applies to the enumeration and chronology recorded in field 863-865 it is recorded there. When the piece designation applies only at the item level, it is recorded in subfield $p of the Item Information field (876-878).
- $q - Piece physical condition
(NR)
When the piece physical condition applies to the entire holdings statement, it is recorded in subfield $q (Piece physical condition) of field 852 (Location). Physical condition information for making preservation decisions is contained in field 583 (Action Note). - $s - Copyright article-fee code
(R)
For information on the copyright article-fee code, see the description of field 018 in the MARC 21 Concise Format for Bibliographic Data. - $t - Copy number
(NR)
A single copy number or a range of numbers for copies that have the same location and call number. - $w - Break indicator
(NR)
Indicates the reason for a break in the enumeration and chronology.- g - Gap break
Part(s) are lacking in the holdings; there is doubt as to the cause of the break; or the cause is not known.
- n - Nongap break
Break is due to unpublished part(s) or a lack of continuity in the enumeration and chronology of the parts.
- g - Gap break
- $x - Nonpublic note (R)
- $z - Public note (R)
- $6 - Linkage (NR) See Control Subfields
- $8 - Field link and sequence number (NR) See Control Subfields
