Structure of the field
First indicator -Field encoding level
# - No information provided
4 - Holdings level 4
Note: First indicators 3, Holdings level 3, and 5, Holdings level 4 with piece designation, will not be used in the project, since these would be used for summary holdings at the non-detailed level, and barcoded holdings, respectively.
Second indicator--Form of holdings
# - No information provided
1 - Uncompressed
0 - Compressed (for completed patterns)
a First level of enumeration (M)
b Second level of enumeration (NR)
c Third level of enumeration (NR)
d Fourth level of enumeration (NR)
e Fifth level of enumeration (NR)
f Sixth level of enumeration (NR)
g Alternative numbering scheme, first level of enumeration (NR)
h Alternative numbering scheme, second level of enumeration (NR)
i First level of chronology (RA)
j Second level of chronology (NR)
k Third level of chronology (NR)
l Fourth level of chronology (NR)
m Alternative numbering scheme, chronology (NR)
n Converted Gregorian year (NR)
o Title of supplement or index
8 Link and sequence number
Note: Several subfields designed for local information will not be used in the project. Refer to the MARC 21 Format for Holdings Data for further information on holdings fields.
The first indicator shows the level of holdings reporting which is being made. Level is determined by the completeness of detail in the report: whether it explicitly states any gaps that might exist. A current statement reports on a single issue; a completed statement reports on a complete segment of the holdings. In either case the reporter may claim the highest level, level 4, for the report. Therefore the first indicator in the 891 $8 86X is 4.
The second indicator shows whether the statement is compressed (expressed as a range between gaps) or uncompressed (expressed in full detail). Again, a report on one issue is by its nature uncompressed, so the second indicator is 1. When that pattern is completed and a new pattern begins, the old pattern is closed off, and the second indicator is changed to 0.
6.2.1. Subfield $9 Tag
Subfield $9 is input as the first subfield of field 891. Its content is the tag of the destination MARC holdings field. In the enumeration/chronology field, the values are:
$9 863 enumeration/chronology for basic bibliographic units
$9 864 enumeration/chronology for supplements
$9 865 enumeration/chronology for indexes
6.2.2. Subfield $8 Link and sequence number
Subfield $8 is input as the second subfield of field 891. In the enumeration/chronology field, it contains the linking number input into the corresponding captions/pattern field, followed by a period and a whole number. Since only one statement will be input in each caption-holdings pair, the sequence number should always be 1. In the case of multiple pairs, the usual arrangement would be
891 $9 853 $8 1 $a
891 $9 863 $8 1.1 $a
891 $9 853 $8 2 $a
891 $9 863 $8 2.1 $a
Defining and inputting the enumeration and chronology
6.2.3. Subfields $a-m Enumeration and chronology data
These subfields carry the basic level of enumeration and chronology for the bibliographic units of a serial. In the enumeration-chronology field for the current pattern, the field will contain data for the first issue to which the captions and pattern apply. For superseded patterns, the field will contain a range consisting of a statement (compressed if possible) of the first bibliographic unit and the last bibliographic unit, joined by a hyphen. The field structure is similar for basic units, supplements, and indexes, with exceptions noted in the following section. (Supplements and indexes, as previously stated, are not usually input.)
126.96.36.199. Subfields $a-h, Enumeration data
Using the earliest piece with the appropriate captions/pattern in hand, or the earliest known, input in subfields $a-f the numbering data corresponding to the captions, arranged from the highest, or primary bibliographic unit, to the lowest. Double-check that the subfields correlate to each other. Convert Roman to Arabic numerals, as prescribed in Z39.71. Convert ordinal numbers to cardinal numbers (but be sure to input the plus sign in front of the corresponding caption). Convert internal hyphens within the enumeration of single bibliographic units not representing a hierarchy of a larger and smaller unit (e.g., 1-1, A-1) to periods (see example). Otherwise, input this enumeration as given on the piece.
Hyphens should be used only for linking the first bibliographic unit to the last bibliographic unit in a statement covering multiple units or volumes.
If the piece has only a chronological designation, input it using the larger, more inclusive division (normally a year) in the first subfield, i.e. subfield $a, followed by internal divisions in subfields $b and following. Use numeric equivalents for months, seasons, and days in the enumeration subfields. See section 188.8.131.52 for the relevant values.
Give years in full (4-digit dates in all positions), even if abbreviated
on the piece. (This is a difference from the practice within the body
of the bibliographic
If the piece in hand is not, or not with certainty, the first piece to be
published with that caption and pattern, the inputter should use angle brackets
around the enumeration and chronology. Separate sets of angle brackets are
used around the content of each individual subfield.
Alternative enumeration corresponding to alternative enumeration captions,
is input in subfields $g and $h. Remember that it is optional and that it is
limited to two levels.
184.108.40.206. Subfields $i-m Chronology data
Input in subfields $i-m the chronology data corresponding to the chronology captions input in the caption/pattern field (891 $9 853). Give years in full, even if abbreviated on the piece. Do not give complete dates of conferences, but only the part that is predictable, i.e. the year. Months and seasons are given as numeric equivalents. For explanation, see section 4.3.
|Month||Month (numeric value)||Season||Season (numeric value)|
220.127.116.11 Closing off the 891 $9 863 for a ceased serial
When a bibliographic record is edited to show that the serial has ceased, data from the last issue is given in field 362 0; or, if the last issue is known but not available, a note is composed in 362 1. (Either operation may be performed by closing off an existing field of the same kind, if it already exists in the record.) The resulting statement includes, if possible, the complete captions, enumeration, and chronology of the first and last issue, e.g., Vol. 1, no. 1 (Jan. 1994)-v. 5, no. 2 (Feb. 1998).
Project participants may do the following when closing a bibliographic record to show cessation, or upon encountering a bibliographic record with closed 362 but open 891 $9 863:
Optionally, the 891 $8 863 may be closed off to match the 362 information.
Change the second indicator of the 891 $9 863 to 0. Close each subfield with
the data from the latest issue or latest issue available. If any lower level
is complete, it may be dropped and the resulting holding compressed. If it
is not known whether the last issue in hand is the actual last issue, place
the uncertain data in angle brackets as described in 18.104.22.168.
6.3. Inputting enumeration and chronology data for supplements and indexes (Optional)
If the piece is a supplement or an index , the procedures are the same, with the following exceptions: There is a subfield available for the title of the supplement or index (subfield $o), and the index coverage should be input with a slash between the first and last unit cited, following the convention that uses a slash within data for one bibliographic unit.
As previously stated, data for supplements and indexes are not usually input
in records for this project.
