863 Enumeration and Chronology-Basic Bibliographic Unit (R)

First Indicator - Field encoding level

The first indicator position contains a value that indicates the level of specificity of the enumeration and chronology in the field. Values 3 and 4 reflect requirements of Levels 3 and 4 of Serial Holdings Statements (ANSI Z39.44) and Holdings Statements for Bibliographic Items (ANSI/NISO Z39.71). Values 3, 4, and 5 correspond to the level of specificity defined for the enumeration and chronology data at the record level by codes 3, 4, and 5 in Leader/17 (Encoding level).

 - No information provided

Value  indicates that that level information is not provided.

Second Indicator - Form of holdings

The second indicator position contains a value that indicates whether the enumeration and chronology in the field is expressed in a compressed or uncompressed (itemized) form and whether the 863 field or an 866 Textual Holdings field should be used for display purposes. Compressed means that the stated field is expressed in a summarized form containing the enumeration and chronology of more than one part expressed as a range of holdings and comprising multiple holdings items. Uncompressed means that each holdings item is itemized, and thus recorded separately.

The value in the second indicator position does not indicate whether an 863 field contains the information required to allow the data to be compressed from an itemized report or expanded to an itemized report by computer algorithm. That information is indicated by the value in the first indicator position (Compressibility and Expandability) of the related 853 Captions and Pattern field to which an 863 field is linked by the linking number in subfield ‡8 (Field link and sequence number).

 - No information provided

Value  indicates that the form of the enumeration and chronology in the field is not specified.

0 - Compressed

Value 0 indicates that the enumeration and chronology in a basic bibliographic unit (field 863) is expressed in a compressed form and that a display of the data may be generated from the field.

863   4   0   ‡8 1.3 ‡a 1917-1940
[A break in the publication pattern is indicated in the second 863 field.]

Unpublished parts may also be indicated by code n (Nongap break) in subfield ‡w (Gap or nongap break indicator). The use of both value 4 and subfield ‡w in the same Enumeration and Chronology field is restricted to instances of consecutive unpublished parts and parts not in the holdings of the reporting organization.

‡a-‡h - Enumeration

Subfields ‡a-‡h contain 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 853 Captions and Pattern field linked to the 863 field, although the same subfields need not always be present. Full correlation of the enumeration level and the caption subfields ‡a-‡h in linked 853/863 fields is recommended in OCLC local holdings records. 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, an 866 Textual Holdings field is used.

When only chronology is used on an item (that is, the item carries no enumeration), the chronology may be contained in either the relevant enumeration subfields ($a-$h) or chronology subfields ($i-$m), with the chronology subfields ($i-$m) preferred whenever possible.

‡a - First level of enumeration

Subfield ‡a contains the highest level of enumeration. The designation for an unnumbered (for example, new ser.) or a numbered (for example, ser. 5) series is considered caption data and is contained in subfield ‡a (First level of enumeration) of the related 853-855 Captions and Pattern field.

‡i-‡m - Chronology

Subfields ‡i-‡m contain the hierarchical levels of chronology that either appear on an item or that are used by the reporting organization to record the receipt of an item. These chronology subfields are correlated with subfields ‡i-‡m in the 853 Captions and Pattern field linked to the 863. Full correlation of the chronology level and the caption subfields ‡i-‡m in linked 853/863 fields is recommended in OCLC local holdings records. 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:

A month code of less than two digits is right justified and the unused position contains a zero.

Days of the month are recorded as two digits in the format 01-31.

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, an 866 Textual Holdings field is used.

When only chronology is used on an item (that is, the item carries no enumeration), the chronology may be contained in either the relevant enumeration subfields ($a-$h) or chronology subfields ($i-$m), with the chronology subfields ($i-$m) preferred whenever possible.

‡o - Title of unit

Subfield ‡o contains the title of the unit (for example, Annual buyer's guide) in the enumeration hierarchy when it has no associated sequencing number. When used, subfield ‡o immediately follows the enumeration subfield to which it applies. When the title of unit applies to the bibliographic entity as a whole, rather than to a portion of its enumeration, field 844 (Name of unit) is used.

‡p - Piece designation

Subfield ‡p contains 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 record, 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 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

Subfield ‡q contains a description of an unusual characteristic of the physical condition of the piece, for example, water spots, ink bleeding.

‡w - Break indicator

Subfield ‡w contains a one-character code that indicates whether a break in the enumeration and chronology contained in multiple 863 fields is due either to published issue(s) lacking in the collection or to unpublished parts or a lack of continuity in the enumeration and chronology of the parts. Subfield ‡w is contained in the Enumeration and Chronology field that represents the holdings that immediately precedes the break. The use of subfield ‡w requires a new field 863 in which the enumeration and chronology following the break is recorded.

g - Gap break

Code g indicates that part(s) are lacking in the holdings of the reporting organization. Code g is also used when there is doubt as to the cause of the break or when the cause is not known.

‡6 - Linkage

See Control Subfields for a description of subfield ‡6.

‡8 - Field link and sequence number

Subfield ‡8 contains data that identifies linked holdings data fields and may also propose a sequence for the linked fields. Subfield ‡8 is required in 863 fields in OCLC local holdings records.

The structure and syntax for subfield ‡8 in the 863 field is: ‡8<linking number>.<sequence number>

The linking number is the first data element used in subfield ‡8 in the 863 field. It is a variable-length whole number that occurs in subfield ‡8 in all 863 fields that are to be linked to an 853 field. Fields with the same linking number are considered linked. A linking number of "0" (zero) is not used in this field.

The sequence number is separated from the linking number by a period "." and is required in 863 fields in OCLC local holdings records. It is a variable-length whole number that may be used to indicate the relative order for display of the linked fields (lower sequence numbers displaying before higher ones).

Subfield ‡8 is always the first subfield in the 863 field.
