FIELD DEFINITION AND SCOPE

Captions that identify the enumeration and chronology levels and codes that define the publication pattern of the holdings described in the 863-865 Enumeration and Chronology fields. Any related 853-855 and 863-865 fields are linked 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.

Guidelines for applying content designators and the input conventions for the 853-855 fields are given in this section.


GUIDELINES FOR APPLYING CONTENT DESIGNATORS

INDICATORS

First Indicator - Compressibility and expandability
Whether a computer algorithm may be used to convert the content of subfields $a-$m in one or more linked enumeration and chronology fields (863-864) from: an itemized report to one that expresses the same range of holdings in terms of the enumeration and chronology of only the first and last part held; or a compressed first-and-last-part-held listing of a range of holdings to an explicit itemization of each part held.
Specific data element requirements for compression and expansion are given in the Input Conventions area of this General Information section. A fuller description of compressibility and expandability is given in the 853-878 Holdings Data-General Information section.
First indicator value does not indicate whether the holdings data in the 863 or 864 field are 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 863 or 864 Enumeration and Chronology field.
0 - Cannot compress or expand
Data in the linked 863 or 864 Enumeration and Chronology field can be neither compressed nor expanded by computer algorithm.
1 - Can compress but not expand
Data in the linked 863 or 864 Enumeration and Chronology field can be compressed but cannot be expanded by computer algorithm.
2 - Can compress or expand
Data in the linked 863 or 864 Enumeration and Chronology field can be either compressed or expanded by computer algorithm.
3 - Unknown
Compressibility and expandability by computer algorithm of the data in the linked 863 or 864 Enumeration and Chronology field is unknown.
First Indicator - Undefined
Undefined and contains a blank (#).
Second Indicator - Caption evaluation
Completeness of the caption levels and whether the captions used actually appear on the bibliographic item.
0 - Captions verified; all levels present
Captions are for all possible levels and they appear on the item.
1 - Captions verified; all levels may not be present
Captions are as they appear on the item but all possible levels may not be included.
2 - Captions unverified; all levels present
Captions are for all possible levels but they are not necessarily the same as they appear on the item.
3 - Captions unverified; all levels may not be present
May not include captions for all possible levels and the ones given are not necessarily the same as they appear on the item.
Second Indicator - Undefined
Undefined and contains a blank (#).

SUBFIELD CODES

$a-$h: Enumeration captions: Captions for the levels of enumeration applicable to a bibliographic item. These caption subfields are correlated with the enumeration subfields $a-$h in the 863-865 Enumeration and Chronology field linked to the 853-855 field, although the same subfields need not always be present. Full correlation of caption and enumeration level 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 enumeration in field 863 or 864 by computer algorithm is desired. If there is no caption on the item for some level, a caption may be invented and enclosed in brackets ([ ]) or an asterisk used in place of data in order to achieve full correlation.
853 03$81$av.$b[no.]
863 40$81.1$a1-7$b1-12
[Display example: v.1:[no.]1-v.7:[no.]12]
When alternative numbering schemes are applicable to an item, subfields $g and $h contain the alternative Enumeration captions. If captions for more than two levels of alternative enumeration are required, an 866-868 Textual Holdings field is used.
When only Chronology captions are used on an item (that is, the item carries no enumeration), the Chronology captions are contained in the relevant enumeration caption subfields ($a-$h). 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, for example, (year).
853 03$81$a(year)
863 40$81.1$a1964-1981
[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 ($a-$f).

864 41$81.1$a16$b1$i1977$j06$k01
[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 desired).
853 03$81$a(unit)
863 #1$81.1$a50 playing cards
$a - First level of enumeration
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.

[Display example: v.7:no.1-3=B:Bd.21-23(1981:Jan.-März)]
$i-$m: Chronology captions: Captions for the levels of chronology applicable to a bibliographic item. These caption subfields are correlated with the chronology subfields $i-$m in the 863-865 Enumeration and Chronology field linked to the 853-855 field, although the same subfields need not always be present. Full correlation of caption and chronology level subfields $i-$m in the 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 chronology in field 863 or 864 by computer algorithm is desired. 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 $m contains the alternative Chronology caption. If captions for more than one level of alternative chronology are required, an 866-868 Textual Holdings field is used.
When only Chronology captions are used on an item (that is, the item carries no enumeration), the Chronology captions are carried in the relevant enumeration caption subfields ($a-$h) and no captions are recorded in subfields $i-$m. 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
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 $o immediately follows the caption to which it refers.

$p - Number of pieces per issuance
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. All codable frequency information should be placed in subfield $w.

[This is 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 edition. The first level enumeration changes once per year at the turn of the calendar year.]
$t - Copy
Caption for the copy number when the 863-865 Enumeration and Chronology field linked to the 853-855 field contains a subfield $t (Copy number).

863 40$81.1$a1-4$b1-3$t3
$u - Bibliographic units per next higher level
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 $a or $g) because there is no higher level. When it is used, subfield $u follows the caption subfield for the enumeration level to which it applies. Not used with subfield $a or $g.
<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 $u is variable in length, no leading zero is used for a single-character number.
853 03$81$av.$bno.$u12$vr$cpt.$u3$wj
[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 $u 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
One-character code that indicates whether the numbering 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 $a or $g). Subfield $v follows the caption subfield and the subfield $u (Bibliographic units at next higher level) for the enumeration to which it applies.
c - Number increments continuously
r - Number restarts at the completion of the unit
$w - Frequency
One-character alphabetic code or a number that indicates the publication frequency of the item. Subfield $w is not related to a specific caption. It is input following the last Chronology caption used. Specific publishing pattern information is contained in subfield $y (Regularity), including exceptions to the frequency coded in this subfield. Subfield $p is also used when both a frequency code and number of pieces per issuance need to be recorded for multipart titles.
Codes
Used for a publishing pattern that has a fundamental periodicity.
a - Annual j - Three times a month
b - Bimonthly k - Continuously updated
c - Semiweekly m - Monthly
d - Daily q - Quarterly
e - Biweekly s - Semimonthly
f - Semiannual t - Three times a year
g - Biennial w - Weekly
h - Triennial x - Completely irregular
i - Three times a week

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

[The bibliographic unit is published four times a year at irregular intervals.]
$x - Calendar change
One or more two- or four-character numeric codes that indicate the chronological point at which the highest level increments or changes.
Codes
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.

853 20$81$av.$bno.$u12$vc$i(year)$j(month)$wm$x07
[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 $x and the codes are separated by a comma. Subfield $x is not related to a specific caption. It is input following the last subfield.
853 22$81$av.$bno.$u6$vc$i(year)$j(month)$wm$x06,12
[A monthly publication which has 6 numbers per volume. The numbers increment continuously, and new volumes begin in June and December.]
$y - Regularity pattern
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
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 Type
Chronology type of regularity pattern is structured as:
<Publication Code><Chronology Code Definition><Chronology Code>,<Chronology Code>,..
May contain one or more chronology codes that are associated with the publication code and chronology code definition that are in the first and second character position of the subfield. The subfield may be repeated to allow for coding more than one publication code/chronology code definition/chronology code string to indicate regular exceptions to a specified regularity pattern (i.e. normalized irregulars).
Chronology Code Definition - Second one-character code in the subfield indicates whether the subsequent Chronology Code(s) represent the name of a day, a numeric month or month and day code, a code for a season of the year, or a code for a week of the month or year. If the subfield describes regularity in terms of enumeration, this code is “e.”
d - Day
m - Month
s - Season
w - Week
y - Year
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.

Enumeration Type
The enumeration type is structured as:
<Publication Code><Enumeration Code Definition><Enumeration Code>,<Enumeration Code>,...
Enumeration codes 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 - 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, lst level
e2- Enumeration, 2nd level
Enumeration Code - 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.
853 02$81$av.$bno.$u6$vr$ws$x01,02,03,04,05,06,07,08,09,10,11,12 $ypw02we,04we$yce21/3,4/6
[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.]
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.
853 02$81$av.$bno.$u52$vc$ww$yce251/52
[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]
853 20$81.0$a(year)$b(month)$c(day)$ww$ycw1203/1204
[Item is published weekly except that it combines the third and fourth weeks in December.]
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.
There may be multiple ways to express the same pattern using the defined publication, chronology and enumeration codes. For instance, the pattern may be expressed enumerating all published issues, or enumerating the omitted issues. The institution should strive for the most succinct method possible that accurately records the pattern.
Regularity pattern codes, along with additional examples are maintained at the Library of Congress and are available online at: www.loc.gov/marc/chrono_patterns.html. Questions on coding patterns or establishing new ones should be addressed to the Network Development and MARC Standards Office, Library of Congress, Washington, D.C. 20540-4402 (Email: [email protected]).
$z - Numbering scheme
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. Subfield $z follows the enumeration subfield ($a-$h) to which it applies.
Type of designation - 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 character
Case - 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 - 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 (# means "blank"):
an## - Arabic numeral
rn## - Roman numeral
sy<symbol># - Symbol

INPUT CONVENTIONS

Compression and expansion requirements - Following conditions must be present in a holdings statement for machine compression or expansion (itemization) to be possible:

Leader/17 Encoding level

Compression only can be applied to Holdings level 4 detailed holdings statements (Leader/17, code 4) and Holdings level 4 detailed holdings statements with piece designation (Leader/17, code 5).

Expansion can be applied to both types of detailed holdings statements (Leader/17, code 4 or 5) and to Holdings level 3 summary holdings statements (Leader/17, code 3).

Correlation of the 853/854 caption and the 863/864 enumeration level subfields

Compression and expansion require that the caption subfields ($a-$m) for each of the applicable levels of enumeration and chronology subfields ($a-$m) must be present in the 853/854 Captions and Pattern field that is linked to the 863/864 Enumeration and Chronology field.

Publication pattern subfields $u-$y

No publication pattern subfields in field 853 or 854 are required for either compression or expansion when the enumeration and chronology in field 863 or 864 consist only of the highest level of enumeration (subfields $a, $g, $i, $m). When subsequent levels are present, the compression or expansion capability requires pertinent publication pattern information in the following subfields:
$u Bibliographic units per next higher level
$v Numbering continuity
$w Frequency
$x Calendar change
$y Regularity pattern
Compression of the contents of subfields $a-$m in field 863 or 864 requires information in subfields $u and $v. Subfield $u may not contain the code var (varies) or und (undetermined).

Expansion of the contents of subfield $a-$m in field 863 or 864 requires information in subfields $u, $v, and $w and may also require information in subfields $x and $y.
Punctuation - Period following an abbreviation used as a caption is carried in the MARC record.
Ordinal Numbers - To indicate that ordinal numbers should be displayed, a plus sign (+) may be used preceding the caption. If no caption is entered, a plus sign may be recorded alone to indicate display of the corresponding 863 subfield as an ordinal number.
853 03$8(year)$b+qtr.
863 41$81.1$a1982$b1
Display example: 
1982:1st qtr.
853 03$81$a+
863 41$81.1$a1
Display example: 
1st
Note that there is no requirement that this technique of distinguishing between ordinal and cardinal numbers be used, nor is there any requirement that any differentiation need be made. A system would require internal language tables to display the correct ordinal numbers. There is no provision in the holdings format for communicating these tables.
Caption displays - If there is no caption on the item for some level, a caption may be invented and enclosed in brackets ([ ]) or an asterisk used in place of data in order to achieve full correlation. Parentheses are used around a caption to suppress display.
853 03$81$av.$b[no.]
[Caption is invented and is not on the piece]
853 20$81$av.$i(year)
863 30$81.1$a1-10$i1988-1998
Abbreviations - Abbreviations used in subfields $a-$h are recorded according to the Anglo-American Cataloguing Rules (Appendix B: Abbreviations).
Field Repeatability - Single 853-855 Captions and Pattern field may apply to more than one 863-865 Enumeration and Chronology field if the contents of the subfields remain constant. The 853-855 fields are repeated when the contents of the subfields varies. For items that have continually varying captions and pattern, an organization may choose to use the Textual Holdings (866-868) fields.
