MARC 21 Concise Bibliographic: Linking Entry Fields (76X-78X)

This is an ARCHIVED VERSION of the 2000 electronic edition of the MARC 21 Concise Formats. Please see www.loc.gov/marc/concise/ for the most up-to-date version of the electronic MARC 21 Concise Formats.

Fields 760-787 contain information that identifies other bibliographic items. Each of the linking entry fields specifies a different relationship between the target item described by the record and a related item. These relationships fall into three categories: 1) 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, translations of the target item); 2) related items that have to be obtained physically in order to use the target item (e.g., the host item for a component part: a journal issue containing a specific article); 3) 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 are designed to generate a note in the record in they appear. They can also provide machine linkage between the bibliographic record for the target item and the bibliographic record for the related item, if the related item is covered by a separate record.

Information for Translators and Other Users
Items highlighted in red indicate changes made after the 1998 edition of the USMARC Concise Formats was published (This publication included the 1994 base text, along with Updates No. 1 (March 1995), No. 2 (March 1996) and No. 3 (July 1997) of the USMARC Format for Bibliographic Data).

Items highlighted in green indicate changes made to the online format only. These changes will be corrected in the 2001 printed edition of the MARC 21 Concise Formats (Available soon).

Target item

a bibliographic item that is the principal or primary unit for the description of which the record was constructed. The target item is the item to which the data in Leader/06 (Type of record) and /07 (Bibliographic level) apply.

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 formulated.

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, an article in a journal).

Constituent unit

a bibliographic item that is part of another item. The constituent unit is physically separate from the item of which it is consider a part.

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; if a record describes one digital item in a set, the host is the set.

Chronological relationship

the relationship in time between bibliographic items (e.g., the relation of a serial to its predecessors and successors).

Horizontal relationship

the relationship between versions of a bibliographic item in different languages, format, media, etc.

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, subseries to main entry series).

RECORD LINKS AND NOTES

Linking Entry Fields (fields 760-787)

These fields carry descriptive data concerning the related item, the control number for the record of the related item, or both. Minimal content designation is provided for the data concerning the related item that is used in the linking entry fields. For data operations requiring fuller content designation, such as indexing and sorting, subfield $w (the record control number for the related item) allows the system to follow that link to the related record to obtain fully content-designated data. Moreover, the coded data in control subfield $7 allows some types of indexing without reference to the actual related record. The value used in the first indicator position of a linking entry field determines whether a note is to be generated from the field.

Linking Entry Complexity Note (field 580)

The Linking Entry Fields are designed to support generation of a note concerning the related item in a display of the record for the target item. When the relationship is too complex to be expressed using a display constant and the data from the linking entry field or the linked record, the note is recorded in the Linking Entry Complexity Note field. When used, this field appears in addition to any relevant 760-787 linking entry field, and no note is generated from the linking entry field.

Linked-Record Requirement (Leader/19)

This data element indicates whether sufficient information is present in the linking entry field to support generation of an eye-readable note that identifies the related item or whether only a related record number is recorded. If only a record number appears, the system will need to obtain the appropriate information from the related record to construct a standard display.
The following subfields or subfield combinations are considered sufficient for display purposes:

• Subfield $a + $t (Main entry heading + Title)
• Subfield $a + $s (Main entry heading + Uniform title)
• Subfield $a (Main entry heading
• Subfield $t (Title)
• Subfield $s (Uniform title)
• Subfield $u (Standard Technical Report Number)
• Subfield $r (Report number)

Added Entries (fields 700-730)

When an added entry is needed for a title used in a linking field, the added entry is recorded in the appropriate 700-730 field. Linking fields are not intended take the place of added entries. Likewise, an added entry in field 700-730 does not take the place of a linking field, as it cannot cause a note to be generated or carry a record link.

Component Parts

The linking entry field 773 (Host Item Entry) is used to link a target item that is an integral part of another item to the record for the other item. For example, in records for journal articles it contains the identification of the journal. In subfield $g of field 773, the exact location of the article in the journal is recorded.
