|A linking entry describes separately cataloged publications that are related to the item you are cataloging. These fields allow the establishment of bibliographic connections among materials with diverse relationships. |
| || |
Linking entry fields do not take the place of authorized access point fields. Use the 7xx or 8xx fields for authorized access points.
Each linking entry field specifies a different bibliographic relationship between the target item described by the record and a related item. These relationships fall into the following groups:
- Related items that assist the user in continuing to search, but are not physically required to obtain the target item (e.g., former entries for serials or translations of the target item)
- Related items that have to be obtained physically in order to use the target item (e.g., the host item for a component part such as a journal issue containing a specific article)
- Related items that are constituent units of a larger whole (e.g., the individual photographs contained in a visual material collection)
The linking entry fields can generate a note in the record in which they appear. Linking entry fields can also provide machine linkage between the bibliographic record for the target item and the bibliographic record for a related item when the related item is represented by a separate record.
|Terms used in linking entry fields || |
Target item. A bibliographic item that is described by the record. The target item is the item to which the data in Type and BLvl apply. The title of the target item is in field 245.
Related item. A bibliographic item that has either a chronological, horizontal, or vertical relationship with a target item, and for which the linking entry field is created.
Host item. A bibliographic item that either physically contains (as in the case of the component part), or bibliographically includes (as in the case of a constituent unit), the subpart that is the target item for the record. For example: if a record describes a journal article, the host is the journal. (Fields 772, 773)
Component part. A bibliographic item that is physically part of another bibliographic item such that the retrieval of the part is dependent on the physical identification and location of the host item (e.g., a chapter in a book or an article in a journal). (Field 774)
Constituent unit. A bibliographic item that is part of another item. The constituent unit is physically separate from the item of which it is considered a part. (Fields 770, 774)
Chronological relationship. The relationship in time between bibliographic items (e.g., the relation of a serial to its predecessors and successors). (Fields 777, 780, 785)
Horizontal relationship. The relationship between versions of a bibliographic item in different languages, format, media, etc. (Fields 765, 767, 775, 776)
Vertical relationship. The hierarchical relationship of the whole to its parts and the parts to the whole (e.g., a journal article to the journal or a subseries to a main series). (Fields 760, 762, 770)
|Construction of linking entries || |
If a separate record for the related publication exists, use that record as the source of data for the linking entry.
Base the identification of the related publication on its authorized access point representing the work (name-title or title). For example, if OCLC record number 6597310 has the following authorized access point with preferred title:
|130 ||0 || ||Monthly digest of statistics (Zimbabwe. Central Statistical Office) |
It could be linked to the related publication in field 780.
|780 ||0 ||0 ||‡t Monthly digest of statistics (Zimbabwe. Central Statistical Office) ‡w (OCoLC)6597310 |
Some records may not have authorized access points/titles or preferred titles because the Library of Congress used the key title and International Standard Serial Number for linking fields prior to AACR2.
|Pre-AACR2 serials || |
You must differentiate pre-AACR2 serials that have the same title proper, but no distinguishing uniform title. Use the following types of information (listed in order of preference) to differentiate among pre-AACR2 serials:
- Name of edition (subfield ‡b)
- Language (subfield ‡e)
- Country (subfield ‡f )
- Other qualifying information (subfield ‡c)
|Use the following subfields in the linking entry fields. See the description of each field for the valid subfields. You are unlikely to use subfields ‡b, ‡c, ‡d, ‡e, ‡f, ‡h, ‡m, ‡n, ‡k, ‡p, ‡r, ‡u, ‡y and ‡z in serial linking entry fields constructed according to RDA or AACR2. |
| ‡a Main entry heading ||The authorized access point data from field 100, field 110 or field 111 in the related record. Individual components of the name are not recorded in separate subfields as they would be in a 1xx field. Use subfield ‡t for the preferred title from field 130 in the related record. |

Instructions for inputting numbers:
The LCCN in subfield ‡w of a linking entry field corresponds to that in field 010 subfield ‡a of the related record. The form input in subfield ‡w is a machine-readable form of the LCCN. Also, there are differences in how the pre-2001 and post-2000 formats of LCCN are recorded in subfield ‡w.
LCCN Pre-2001 format:
- Input DLC enclosed within parentheses.
- Input three leading blank spaces between the symbol (DLC) and the year numbers if the LCCN has no prefix. If the LCCN has a prefix of fewer than three characters, leave the appropriate number of blank spaces following the prefix.
- Input the two-digit year information.
- Do not input a hyphen.
- Input the six-digit number. Input leading zeros where necessary.
- Do not input trailing blank following the number. (If trailing blank is input, the OCLC system removes it.)
- Do not input alphabetic identifiers and/or revision dates.

Up to four one-character codes that indicate special characteristics of the linked entry. Subfield ‡7 is generally not used.
Because the definition of the codes in subfield ‡7 are dependent on the character position in which they occur, the coding of any character position mandates that each preceding character position contains a code. Succeeding character positions need not be used. For example, if position /0 and /1 are not applicable, but position /2 is, then position /0 and /1 contain code n.
