Field definition and scope
This field contains information that describes an item that is a reproduction of original materials. The original item is described in the main portion of the bibliographic record and data relevant to the reproduction are given as a note in field 843 in the holdings record when they differ from the information describing the original. It is used whenever an institution chooses to have the description reflect the original and the notes reflect information about the copy. This field is similar to field 533 (Reproduction Note) defined in OCLC's bibliographic format
Guidelines for applying content designations
For records formulated according to AACR cataloging rules, elements of field 843 are generally separated by ISBD punctuation.
Both indicators are undefined; each contains a blank ().
First Indicator - Privacy
Second Indicator - Undefined

‡3 - Materials specified
Subfield ‡3 contains information that indicates the part of the described material to which the field applies. When separate holdings records are made for each part of a bibliographic item, each record may contain a field 843 that contains a subfield ‡3 to specify the part to which the note applies. When holdings for all of the parts of a bibliographic item are contained in one holdings record (and there is no 863-865 Enumeration and Chronology field), subfield ‡3 may be used whenever a data element in field 843 differs for a specified part of the item.

‡5 - Institution to which field applies
Subfield ‡5 contains the MARC code of the institution or organization that holds the copy to which the data in the field applies. It is used for institution-specific information that may or may not apply to the universal use of the holdings record. See MARC Code List for Organizations, which also includes links to Canadian, United Kingdom, and German MARC Organization Code lists.
‡7 - Fixed-length data elements of reproduction
Subfield ‡7 contains fifteen character positions (designated 0, 1-4, etc.) that contain coded information pertaining to the reproduction. The coded data elements correspond to those in the 008 field of the MARC 21 Format for Bibliographic Data. The data elements are positionally defined. All character positions must contain either a defined code or a fill character (|).
0 Type of date/Publication status
Subfield ‡7/0 contains a one-character alphabetic code that indicates for the reproduction the type of dates given in 1-4 (Date 1) and 5-8
(Date 2). For serially-issued items, it also indicates the publication status of the reproduction; a serial code c, d, or u as described in 008/06
(Type of date/Publication status) is used.
Any code found in the description of 008/06 (Type of date/Publication status) may be used except code r (Reprint/reissue date and original
1-4 Date 1
Subfield ‡7/1-4 contains a date in the form yyyy specified by the value in 0.
For non-serials, 1-4 contains Date 1 information associated with the reproduction. The information is generally related to information found in
subfield ‡d of field 843.
For serially-issued items, 1-4 contains the original beginning date of publication of the issues that have been reproduced, as indicated in
subfield ‡m of field 843.
In coding these positions, the guidelines in 008/07-10 (Date 1) of the MARC 21 Format for Bibliographic Data are followed.
5-8 Date 2
Subfield ‡7/5-8 contains a date in the form yyyy specified by the value in 0.
For non-serials, 5-8 contains Date 2 information associated with the reproduction. The information is generally related to information found in
subfield ‡d of field 843.
For serially-issued items, 5-8 contains the original ending date of publication of the issues that have been reproduced, as indicated in subfield
‡m of field 843.
In coding these positions, the guidelines in 008/11-14 (Date 2) of the MARC 21 Format for Bibliographic Data are followed.
9-11 Place of publication, production, or execution
Subfield ‡7/9-11 contains a two- or three-character alphabetic code that indicates the place of publication, production, or ;execution of the
In coding these positions, the guidelines in 008/15-17 (Place of publication, production, or execution) of the MARC 21 Format for Bibliographic
Data are followed.

Subfield ‡7 is always the last subfield in the field.
‡8 - Field link and sequence number
Subfield ‡8 contains data that identifies linked fields and may also propose a sequence for the linked fields. Subfield ‡8 may be repeated to link a field to more than one other group of fields.
The structure and syntax for the field link and sequence number subfield is: ‡8<linking number>.<sequence number>
The linking number is the first data element in the subfield and required if the subfield is used. It is a variable-length whole number that occurs in subfield ‡8 in all fields that are to be linked. Fields with the same linking number are considered linked. A linking number of "0" (zero) is not used in this field.
The sequence number is separated from the linking number by a period "." and may be optional. It is a variable-length whole number that may be used to indicate the relative order for display of the linked fields (lower sequence numbers displaying before higher ones).
Subfield ‡8 is always the first subfield in the field when it is used.
