Linking general

Linking between records on basis of PPN’s is a feature of CBS that exists for several decades now. In the CBS MARC 21 cataloguing format, subfield $Z is used; in PICA+ the corresponding subfield is $9.

Linking is a complex functionality of a CBS. Three kinds of links can be discriminated:

  • Links between bibliographic and authority records, e.g. a name of an author of a book or article linked to an authority file1 of personal authors or a subject heading linked to an authority file of subject headings
  • Links between bibliographic records
  • Links between authority records

Linking between records on basis of PPN’s is a feature of CBS that exists for several decades now. Thus, when we talk about links in this documentation, we mean the PPN links between records.

In the CBS MARC 21 cataloguing format, subfield $Z is used; in PICA+ the corresponding subfield is $9.

Kinds of links 

Linking is a complex functionality of a CBS. Three kinds of links can be discriminated:

  • Links between bibliographic and authority records, e.g. a name of an author of a book or article linked to an authority file of personal authors or a subject heading linked to a authority file of subject headings.
  • Links between bibliographic records
    • Part of a series linked to the record that describes the series as such.
    • Part of a multivolume publication linked to the record that describes the multivolume as such.
    • Links to related bibliographic records, e.g. translations, former titles, etc.
    • Links to related bibliographic records e.g. on another carrier.
    • Information concerning the host item for the constituent unit described in the record (vertical relationship). E.g. a link from an article to the serial, from a track to the cd on which the track is published.
  • Links between authority records
    • The “see also” links within the same authority file.
    • The “see also” links between several kinds of authority files, e.g. a personal name linked to a corporate body (e.g. his/her employer) or to a topical term e.g. the topic in which a person is specialized in.
