863 - 865 Enumeration and Chronology - General Information (Variable Data Fields)
Definition and Scope:
A 863-865 Enumeration and Chronology field contains a description of the holdings of a bibliographic item in the collections of the reporting organization. The captions that identify the enumeration and and chronology levels and the codes that define the publication pattern of the holdings are contained in the 853-855 Captions and Pattern field that is linked to the 863-865 field by a number in subfield $a (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 853-878 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 Input Conventions area of the 853-855 Captions and Pattern - General Information section. A description of compressibility and expandability is given in the 853-878 Holdings Data General Information section.
Guidelines for applying content designators and the input conventions for the 863-865 fields are given in this section.
Guidelines for Applying Content Designators:
Indicators:
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 Serials Holdings Statements (ANSI Z39.44) and Holdings Statements for Non-Serials Items (ANSI/NISO Z39.57). 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).
3 Holdings level 3 [863 /864 ]
5 Holdings level 4 with piece designation
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 863-865 field or an 866-868 Textual Holdings field should be used for display purposes. A compressed form means that a range of holdings is recorded in terms of the enumeration and chronology of only the first and last parts held., An uncompressed form means that each part in a range of holdings is explicitly recorded.
The value in the second indicator position does not indicate whether an 863 or 864 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 or 854 Captions and Pattern field to which an 863 or 864 field is linked by the linking number in subfield $8 (Link and sequence number).
0 Compressed [863 /864 ]
2 Compressed, use textual display [863 /864 ]
3 Uncompressed, use textual display
4 Item(s) not published [863 /864 ]

Content Designator History:
$x Nonpublic note
$z Public note
In 1987, subfield $x was defined for nonpublic notes and subfield $z (Note) was redefined to include only public notes. Prior to that change, both public and nonpublic notes were contained in subfield $z.
