6. INSTRUCTIONS FOR USING 891 TO INPUT ENUMERATION AND CHRONOLOGY
DATA (86X)
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)
Subfields
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.
6.1. Indicators
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. Subfields
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.)
6.2.3.1. 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.
$a 1.1-1.33
$a A.1-A.50
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 6.2.3.2 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 record.)
Examples
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.
Example
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.
6.2.3.2. 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) |
|---|---|---|---|
| January | 01 | Spring | 21 |
| February | 02 | Summer | 22 |
| March | 03 | Autumn | 23 |
| April | 04 | Winter | 24 |
| May | 05 | ||
| June | 06 | ||
| July | 07 | ||
| August | 08 | ||
| September | 09 | ||
| October | 10 | ||
| November | 11 | ||
| December | 12 |
6.2.3.3 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 6.2.3.1.
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.
