Definition

Information about the publication patterns for serials. Guidelines for the use of field 891 are available in the CONSER Guidelines for Input of Caption/Pattern and Holdings Data, 4.1. Use of the OCLC 891 field.

Field 891 embeds the MARC holdings fields 853, 854, 855, 863, 864 and 865. Use subfield ‡9 to record the MARC holding field. Define all other indicators and subfields to correspond to the field recorded in subfield ‡9. Repeat field 891 for every MARC field embedded in subfield ‡9. For more information about the indicators and subfields, see MARC 21 Format for Holdings Data ( http://www.loc.gov/marc/holdings/echdhome.html).

1st Indicator

Subfield 9 dependent. All indicator values have meaning only within the MARC field definition for the field recorded in subfield ‡9.
 
blank character , 0-5 Subfield ‡9 dependent . Indicator definition dependent on the field recorded in subfield ‡9.

2nd Indicator

Subfield 9 dependent. All indicator values have meaning only within the MARC field definition for the field recorded in subfield ‡9.
 
blank character , 0-5 Subfield ‡9 dependent . Indicator definition dependent on the field recorded in subfield ‡9.

Subfields

 
‡a First level of enumeration   The highest level of enumeration.

‡f Sixth level of enumeration   The sixth level of enumeration.
‡g Alternative numbering scheme, first level of enumeration   The highest level of alternative numbering scheme.
‡h Alternative numbering scheme, second level of enumeration   The second level of alternative numbering scheme.
‡i First level of chronology   The highest level of chronology.
‡j Second level of chronology   The second level of chronology.
‡k Third level of chronology   The third level of chronology.

‡m Alternative numbering scheme, chronology   The alternative chronology scheme.
‡n Pattern note [Only valid for fields 853–855]   The explanatory note citing the specific year and issue used to prepare the regularity pattern coding expressed in the field. Only valid for fields 853–855.
‡n Converted Gregorian year [Only valid for fields 863–865]   The Gregorian-calendar conversion of a year that is recorded in a non-Gregorian scheme in a chronology-level subfield. Only valid for fields 863–865.
‡o Type of unit [Only valid for field 853]   The type of unit (e.g., annual buyer's guide, subject index) in the enumeration hierarchy when it has no associated sequence numbering. When used, subfield ‡o immediately follows the caption to which it refers. Only valid for field 853.
‡o Type of unit [Only valid for field 854]   The type of unit (e.g., annual buyer's guide, subject index) in the enumeration hierarchy when it has no associated sequence numbering. When used, subfield ‡o immediately follows the caption to which it refers. Only valid for field 854.
‡o Type of unit [Only valid for field 855]   The type of unit (e.g., annual buyer's guide, subject index) in the enumeration hierarchy when it has no associated sequence numbering. When used, subfield ‡o immediately follows the caption to which it refers. Only valid for field 855.
‡o Title of unit [Only valid for field 863]   Title of unit (e.g., annual buyer's guide, subject index) in the enumeration hierarchy when it has no associated sequence numbering. When used, subfield ‡o immediately follows the enumeration subfield to which it refers. 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. Only valid for field 863.
‡o Title of unit [Only valid for field 864]   Title of unit (e.g., annual buyer's guide, subject index) in the enumeration hierarchy when it has no associated sequence numbering. When used, subfield ‡o immediately follows the enumeration subfield to which it refers. 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. Only valid for field 864.
‡o Title of unit [Only valid for field 865]   Title of unit (e.g., annual buyer's guide, subject index) in the enumeration hierarchy when it has no associated sequence numbering. When used, subfield ‡o immediately follows the enumeration subfield to which it refers. 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. Only valid for field 865.
‡p Number of pieces of issuance [Only valid for fields 853–855]   A numeric value that represents the number of physical parts or pieces received per issuance. This technique allows for describing the behavior of items issued in parts. Subfield ‡p is only coded in cases where the number of parts or pieces is different from the publishing frequency expressed in subfield ‡w. Place all codable frequency information in subfield ‡w. Only valid for fields 853–855.
‡p Piece designation [Only valid for fields 863–865]   An identification of a piece. The designation may be an identification number such as a bar code number or an accession number. Only valid for fields 863–865.
‡u Bibliographic units per next higher level [Only valid for fields 853–855]   Either a number that specifies the total number of parts that comprise the next higher level of enumeration or the code var or und. Use subfield ‡u with each level of enumeration expect the first level. Only valid for fields 853–855.
‡v Issuing date [Only valid for field 865]   Date of issuance of an index. Only valid for field 865.
‡v Numbering continuity [Only valid for fields 853–855]   A one-character code that indicates whether the enumeration has continuously incrementing numbers or whether the numbering restarts at the completion of a specific unit. Use subfield ‡v with each level of enumeration except the first level. Only valid for fields 853–855.
‡w Frequency [Only valid for fields 853–855]   A one-character alphabetic code or a number that indicates the publication frequency of the item. Only valid for fields 853–855.
‡w Break indicator [Only valid for fields 863–865]   A one-character code that indicates whether a break in the enumeration and chronology contained in multiple 863–865 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. Only valid for fields 863–865.
‡x Calendar change [Only valid for fields 853–855]   One or more two- or four-character numeric codes that indicate the chronological point at which the next higher level increments or changes. Only valid for fields 853–855.
‡y Regularity pattern [Only valid for fields 853–855]   Codes that describe the regularity of the publishing pattern codes in subfield ‡w. Only valid for fields 853–855.
‡z Numbering scheme [Only valid in fields 853–855]   A six-character code string designating the numbering schemes used on a publication. The codes allow for recording different numbering schemes at different levels of enumeration. Only valid for fields 853–855.
‡z Public note [Only valid for fields 863–865]   A note pertaining to all or part of the field that is in a form adequate for public display. Only valid for fields 863–865.
‡2 Source of caption abbreviation [Only valid in fields 853–855]   MARC code that identifies the source of the abbreviations used in the captions of the field. See MARC Code Lists for Relators, Sources, Descriptive Conventions ( http://www.loc.gov/marc/relators/relahome.html). Only valid for fields 853–855.
‡3 Materials specified [Only valid in fields 853–855]   Information that specifies the range of volumes or dates to which the field applies. Only valid for fields 853–855.
‡8 Field link and sequence number   Information that identifies linked fields. Use subfield ‡8 also to propose a sequence for the relative order of display of the linked fields.
‡9 Tag of the MARC holdings field   Only valid contents are 853, 854, 855, 863, 864 and 865.
 

Subfield ‡9 is always the first subfield in the field. Subfield definition is dependent on the field recorded in subfield ‡9. All subfield code values have meaning only within the MARC field definition for the field recorded in subfield ‡9.

Example

The following is a 853 field for a journal and the associated 863 field for the first issue:

891 ‡9 853 ‡8 1 ‡a v. ‡b no. ‡u 12 ‡v r ‡i (year) ‡j month ‡w m ‡x 01
891 3 ‡9 863 ‡8 1.1 ‡a 1 ‡b 1 ‡i 1987 ‡j 01
