854 Captions and Pattern-Supplementary Material (R)

First Indicator - Compressibility and expandability

The first indicator position in field 854 contains a value that indicates whether the holdings data contained in the 864 Enumeration and Chronology field to which the Captions and Pattern field is linked can be compressed or expanded by computer algorithm. The specific data element requirements for compression and expansion are given in the Input Conventions area at the end of this section. A fuller description of compressibility and expandability is given in the 853-878 Holdings Data-General Information section.

The first indicator value does not indicate whether the holdings data in the 864 field is already expressed in a compressed or expanded form. This condition is indicated by the value in the second indicator position (Form of holdings) in the 864 Enumeration and Chronology field.

0 - Cannot compress or expand

Value 0 indicates that the data in the linked 864 Enumeration and Chronology field can be neither compressed nor expanded by computer algorithm.

1 - Can compress but not expand

Value 1 indicates that the data in the linked 864 Enumeration and Chronology field can be compressed but cannot be expanded by computer algorithm.

2 - Can compress or expand

Value 2 indicates that the data in the linked 864 Enumeration and Chronology field can be either compressed or expanded by computer algorithm.

3 - Unknown

Value 3 indicates that the compressibility and expandability by computer algorithm of the data in the linked 864 Enumeration and Chronology field is unknown.

Second Indicator - Caption evaluation

The second indicator position in field 854 contains a value that indicates the completeness of the caption levels and whether the captions used actually appear on the bibliographic item.

0 - Captions verified; all levels present

Value 0 indicates that the field contains captions for all possible levels and that they appear on the item.

1 - Captions verified; all levels may not be present

Value 1 indicates that the field contains captions as they appear on the item but that all possible levels may not be included.

2 - Captions unverified; all levels present

Value 2 indicates that the field contains captions for all possible levels but that they are not necessarily the same as they appear on the item.

3 - Captions unverified; all levels may not be present

Value 3 indicates that the field may not include captions for all possible levels and that the ones given are not necessarily the same as they appear on the item.

‡a-‡h - Enumeration captions

Captions for the levels of enumeration applicable to a bibliographic item. These caption subfields are correlated with the enumeration subfields ǂa-ǂh in fields 863-865, although the same subfields need not always be present. Full correlation of caption and enumeration level subfields ǂa-ǂh in linked 853-855/863-865 fields is not required when captions are not needed for displaying the holdings statement. Full correlation is required when compression or expansion of the enumeration in field 863 or 864 by computer algorithm is needed. If there is no caption on the item for some level, a caption may be supplied and enclosed in brackets ([ ]) or an asterisk ( * ) may be used in place of data in order to achieve full correlation.

863    4    0    ǂ8 1.1 ǂa 1-7 ǂb 1-12
[Display example: v.1:[no.]1-v.7:[no.]12]

When alternative numbering schemes are applicable to an item, subfields ǂg and ǂh contain the alternative enumeration captions. If captions for more than two levels of alternative enumeration are required, an 866-868 field is used.

When only chronology captions are used on an item (that is, the item carries no enumeration), the chronology captions are contained in the relevant enumeration caption subfields ǂa-ǂh. If a chronology caption is not to be used in a display of the 863-865 field, it is enclosed in parentheses, for example, (year).

863    4    0    ǂ8 1.1 ǂa 1964-1981
[An annual publication identified only by year]

When a supplement or index designation is used as a caption (which occurs if its numbering relates to a particular volume or part of the bibliographic unit, e.g., v. 9, suppl. 1-3), the designation is contained in the relevant enumeration caption subfield (subfields ǂa-ǂf).

[Display example: v.16:suppl.1 (1977:June 1)]

When the enumeration consists of the number of units held followed by a term describing the units, the entire phrase is contained in the appropriate 863-865 field, and the 853-855 field contains the term unit (in parentheses if display is not needed).

‡a - First level of enumeration

Subfield ‡a contains the caption for the highest level of enumeration. The designation for an unnumbered (e.g., new ser.) or a numbered (e.g., ser. 5) series is considered part of the caption.

‡f - Sixth level of enumeration

Subfield ‡f is unlikely to be used.

‡g - Alternative numbering scheme, first level of enumeration

Subfield ‡g contains the caption for the highest level of an alternative numbering scheme.

‡i-‡m - Chronology captions

Subfields ‡i-‡m contain the captions for the levels of chronology applicable to a bibliographic item. These caption subfields are correlated with the chronology subfields ‡i-‡m in the 864 Enumeration and Chronology field linked to the 854 field, although the same subfields need not always be present. Full correlation of caption and chronology level subfields ‡i-‡m in the 854/864 fields is recommended in OCLC local holdings records. Because bibliographic items generally do not carry chronology captions, a caption may be invented and enclosed in brackets ([ ]) in order to achieve full correlation.

When an alternative chronology scheme is applicable to an item, subfield ‡m contains the alternative chronology caption. If captions for more than one level of alternative chronology are required, an 867 Textual Holdings field is used.

When only Chronology captions are 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. If a Chronology caption is not to be used in a display of the 863-865 Enumeration and Chronology field, it is enclosed in parentheses, e.g., (year).

‡o - Type of unit

Subfield ‡o contains the caption that describes 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 ǂo immediately follows the caption to which it refers.

‡p - Number of pieces per issuance

Subfield ‡p contains the 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 ǂp is only coded in cases where the number of parts or pieces is different from the publishing frequency expressed in subfield ǂw. All codable frequency information should be placed in subfield ǂw.

[A semiannual publication issued twice per year in January and July, with six issues published at each time. It restarts its volume numbering (second level enumeration) with every issuance. The first level enumeration changes once per year at the start of the calendar year.]

‡u - Bibliographic units per next higher level

Subfield ‡u contains the number (or the code var or und) that specifies the total number of parts that comprise the next higher level of enumeration. May be used with each level of enumeration except the first level (subfield ǂa or subfield ǂg) because there is no higher level. When it is used, subfield ǂu follows the caption subfield for the enumeration level to which it applies.

n - Number of parts. Total number of parts that constitute the next higher level of enumeration for example, a quarterly publication requires 4 issues to make 1 volume. Because subfield ǂu is a variable length, no leading zero is used for a single-character number.

853    0    3    ǂ8 1 ǂa v. ǂb no. ǂu 12 ǂv r ǂc pt. ǂu 3 ǂw j
[The bibliographic unit consists of 12 numbers per volume and 3 parts per number]

Combined issues are counted as one part.

[Example of monthly serial with four combined issues]

var - Varies. The total number of parts that constitute the next higher level of enumeration varies so much that a specific number in subfield ǂu would be meaningless.

und - Undetermined. The next higher level of enumeration is known to have parts but the number of parts is unknown.

‡v - Numbering continuity

Subfield ‡v contains one-character code that indicates whether the number of the described level consists of continuously incrementing numbers or numbers that restart at the completion of the unit.

May be used with each level of enumeration except the first level (subfield ǂa or subfield ǂg). Subfield ǂv follows the caption subfield and the subfield ǂu for the enumeration to which it applies.

c    Number of increments continuously
r    Number restarts at the completion of the unit

‡w - Frequency

Subfield ‡w contains one-character alphabetic code or a number that indicates the publication frequency of the item. Subfield ǂw is not related to a specific caption. It is input following the last chronology caption used. Specific publishing pattern information is contained in the subfield ǂy, including exceptions to the frequency coded in this subfield. Subfield ǂp is also used when both a frequency code and number of pieces per issuance need to be recorded for multipart titles.

Number

Used to specify the number of issues per year when no codable periodicity exists. Because subfield ǂw is variable in length, no leading zero is used for a single-character number.

853    0    2    ǂ8 1 ǂa (year) ǂb (month) ǂw 4 ǂy pm03,06,08,12

[The bibliographic unit is published four times a year at irregular intervals]

‡x - Calendar change

Subfield ‡x contains one or more two- or four-character numeric codes that indicate the chronological point at which the highest level increments or changes.

Codes.

A two-character code identifies the month or season of change. A four-character code in the pattern mmdd (2 for the month and 2 for the day) identifies the month and day of change. A month or day code of less than two digits is right justified and the unused position contains a zero.

[A monthly publication consisting of 12 numbers per volume; the volume number increments in July]

When there is more than one change in a year for example, 12 numbers per year are issued as 2 volumes per year, all of the calendar change codes are contained in one subfield ǂx and the codes are separated by a comma. Subfield ǂx is not related to a specific caption. It is input following the last subfield.

853    2    2    ǂ8 1 ǂa v. ǂb no. ǂu 6 ǂv c ǂi (year) ǂj (month) ǂw m ǂx 06,12
[A monthly publication which has 6 numbers per volume. The numbers increment continuously, and new volumes begin in June and December.]

‡y - Regularity pattern

Subfield ‡y contains codes that describe the regularity of the publishing pattern coded in subfield ‡w (Frequency). The subfield may be structured as either a chronology type or enumeration type. Both types begin with a publication code.

Publication Code

The first one-character code in both the chronology type and enumeration type indicates whether the subsequent codes refer to the publication or the nonpublication of part(s) of the item or the combination of either enumeration or chronology elements.

c - Combined

o - Omitted

p - Published

Chronology Code

Designation of the part of the item for which regularity pattern information is provided. Multiple codes are separated by a comma. A slash ( / ) is used to designate combined issues.

Two-character alphabetic or numeric codes are used for days, weeks, months, and/or seasons. A four-character code is used to indicate a year or year combination. A code of less than two digits is right justified, and the unused position contains a zero.

[Item is published every other year combining chronology to reflect the span of coverage.]

Enumeration Type

The enumeration type is structured as:

<Publication Code><Enumeration Code Definition>,<Enumeration Code><Enumeration Code>,...

An enumeration code may occupy the second and third positions after subfield ‡y to provide for regularity patterns for items that use only enumeration for sequencing and/or those items whose sequencing must be specified separately when combinations occur.

Enumeration Code Definition

The second code in the subfield indicates whether the subsequent codes represent enumeration rather than chronology. When code "e" is used, an additional numeric code is added to indicate the level of enumeration to which the regularity applies.

e1 - Enumeration, 1st level

e2 - Enumeration, 2nd level

Enumeration Code

The enumeration code following the enumeration code definition indicates the designation of the issues of the item for which regularity pattern information is provided. Multiple designations are separated by a comma. A slash (/) is used to designate a combined issue.

854   0   2   ‡8 1 ‡a v. ‡b no. ‡u 6 ‡v r ‡w s ‡x 01,02,03,04,05,06,07,08,09,10,11,12 ‡y pw02we,04we ‡y ce21/3,4/6
[Item is published twenty-four times per year on the second and fourth Wednesdays of every month. The second level of enumeration combines numbers 1 to 3 on the second Wednesday of every month and numbers 4 to 6 on the fourth Wednesday of every month.]

The presence of continuous numbering (subfield ‡v, code c) in conjunction with an enumeration code signals the combination of specific numbers in the sequence of specific issues. Because of the continuous numbering, the actual enumeration values cannot be used to express the enumeration in subfield ‡y. Enumerative values must be represented in terms of the number of issues expected to be published to allow combined issue prediction to occur.

854   0   2   ‡8 1 ‡a v. ‡b no. ‡u 52 ‡v c ‡w w ‡y ce251/52
[Item is published weekly except for a combination in the last two weeks of December. Since issue description is limited to enumeration only, and the second level enumeration is also continuous, the pattern represents the issue combination in terms of combining the fifty-first and fifty-second issues published that year.]

Automated systems may construct algorithms to predict the second level of continuous enumeration based on the starting value of the second level of enumeration at the beginning of the subscription cycle.

The Regularity pattern codes, along with additional examples, are maintained by the Library of Congress and are available online at www.loc.gov/marc/chrono_patterns.html.

‡z - Numbering scheme

Subfield ‡z contains a six-character code string used to designate the numbering scheme used on a publication. The codes allow for recording different numbering schemes at different levels of enumeration.

Type of designation

The first one-character code indicates whether the numbering is a number, letter or combined (number first or letter first). Combined should only be used when one of the elements is a constant designation (e.g., 1a, 2a, 3a), rather than actually two different levels of enumeration (e.g., 1a, 1b, 1c).

a - Number

b - Letter

c - Combined, number first

d - Combined, letter first

e - Symbol or special character

Case

The second one-character code indicates if a numbering scheme is conveyed as alphas and applies both to those coded in the previous position as "b" or to Roman numerals.

a - No case

b - Lower case

c - Upper case

d - Mixed case

Script Code/Type Code

The third through sixth positions indicate either the script used in the numbering scheme or, for numerals or symbols that are not in alternate scripts, the type of numeral or symbol used. The script code is a four-character code from the list at www.unicode.org/iso15924/. The type code is as follows:

an   - Arabic numeral

rn    - Roman numeral

sy<symbol>  - Symbol

‡2 - Source of caption abbreviation

‡2 contains the MARC code that identifies the source of the abbreviations used in the captions of the field. Code from Caption Abbreviation Source Codes.

‡3 - Materials specified

Subfield ‡3 contains information that specifies the range of volumes or dates to which the field applies.

‡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 854 fields in OCLC local holdings records.

The structure and syntax for subfield ‡8 in the 854 field is: ‡8<linking number>

The linking number is the only data element used in subfield ‡8 in the 854 field. It is a variable-length whole number that occurs in subfield ‡8 in all 864 fields that are to be linked to the 854 field. Fields with the same linking number are considered linked. A linking number of "0" (zero) is not used in this field.

Subfield ‡8 is always the first subfield in the 854 field.
