4 - -   LINKING ENTRY BLOCK

STRUCTURE OF LINKING ENTRY FIELDS


This structure applies to all 4-- linking entry fields.

Definition and Scope of Fields


"The primary purpose of UNIMARC is to facilitate the international exchange of bibliographic data in machine readable form between national bibliographic agencies. UNIMARC may also be used as a model for the development of new machine readable bibliographic formats" — Purpose and Scope of UNIMARC.

It is therefore important that the UNIMARC format be hospitable to other MARC formats: otherwise conversion to and from UNIMARC is difficult or even impossible.

For this reason the technique of embedded fields has been supplemented by a technique using standard subfields. The structure of the agency's records will determine which system of linking entry fields is used.

Where there is a choice of system, the agency should weigh the advantages of the linking entry system, which allows fuller although more complex entries, against the advantages of the standard subfield system, which is easier to implement.

A statement that linking fields are present or absent together with a note of the type of contents in such linking fields, should be given in the documentation to accompany exchange records. For details, see Appendix K.

Within the Linking Entry Fields Section, both methods are described in the order: (A) embedded fields technique then (B) the standard subfields technique. All examples illustrate both methods.

Each linking entry field in a record will contain subfields that identify the item to which the link is being made. The data in this field should be sufficient to identify the record for the item being linked to, or, if there is no record, to identify the item itself.

In the following list the fields are labelled by the type of record to which the link is being made, e.g. 410 SERIES is used in a sub series record to link to the series of which it is a part.

The following fields are defined:

Series, supplements, etc.

410 Series
