General
AdditionalFieldsInZ3950ResultAuthSearch
Version
This system preference was introduced in version 23.11 of Koha.
Asks: Display the MARC field/subfields ___ in the ‘Additional fields’ column of Z39.50 search results (use comma as delimiter e.g.: “001, 035$a”).
Description:
This system preference lets you display additional information from the MARC record in the authority Z39.50/SRU search result lists.
AuthDisplayHierarchy
Asks: ___ broader term/narrower term hierarchies when viewing authorities.
Default: Don’t show
Values:
Don’t show
Show
Description:
When set to ‘Show’ broader and narrower ‘See also’ references will be displayed in a tree at the top of the record in both the staff interface and the OPAC.
For MARC21, in order for this display to appear, the records must have 5XX with the relationship code in $w and the authority number (authid) in $9.
Note
The relationship codes in $w can be found on the Library of Congress website under Tracings and references-General information
g - Broader term
h - Narrower term
For example, the records in the above screenshot have the following information:
Authority #3 001 3 151 $a Germany 551 $w h $a Baden-Württemberg (Germany) $9 4 Authority #4 001 4 151 $a Baden-Württemberg (Germany) 551 $w g $a Germany $9 3 551 $w h $a Konstanz (Germany) $9 5 Authority #5 001 5 151 $a Konstanz (Germany) 551 $w g $a Baden-Württemberg (Germany) $9 4Warning
The relationships must be bidirectional, meaning the broader term must reference the narrower term and the narrower term must reference the broader term.
Linker
These preferences will control how Koha links bibliographic records to authority records. All bibliographic records added to Koha after these preferences are set will link automatically to authority records, for records added before these preferences are set there is a script (misc/link_bibs_to_authorities.pl) that your system administrator can run to link records together.
AutoLinkBiblios
Asks: ___ attempt to automatically link headings when saving records in the cataloging module.
Default: Don’t
Values:
Do
Don’t
Description:
This system preference determines whether or not Koha will attempt to link terms in authority controlled field to existing authority records upon saving a new bibliographic record.
This system preference is used when creating new bibliographic records. CatalogModuleRelink and LinkerRelink are used when editing bibliographic records.
If set to “Do”, Koha will search in the thesaurus to find a matching authority record. If it finds one, it will link it. If it finds more than one, LinkerModule will determine which one is linked.
If set to “Don’t”, no linking attempt will be made when saving a new bibliographic record.
CatalogModuleRelink
Asks: ___ automatically relink headings that have previously been linked when saving records in the cataloging module.
Default: Don’t
Values:
Do
Don’t
Description:
This system preference determines whether or not authority links are checked and adjusted when saving a bibliographic record.
When set to “Do”, Koha will automatically relink headings when a record is saved in the cataloging module when LinkerRelink is turned on, even if the headings were manually linked to a different authority by the cataloger.
Note
This system preference requires that AutoLinkBiblios be set to “Do”.
LinkerConsiderThesaurus
Asks: ___ compare the source for 6XX headings to the thesaurus source for authority records when linking.
Default: Don’t
Values:
Don’t
Do
Description:
This system preference is used to enable multiple thesauri support for authorities.
The thesaurus used for the term is added to the authority record using 040$f.
In the bibliographic record, set the second indicator to 7 for 650 and add the source to 650$2. For local terms, use 4 (Source not specified) as the indicator.
Example for a bibliographic record:
650 _ 0 $a Feminism 650 _ 7 $a Feminism $2 sao 650 _ 7 $a Feminism $2 barn
The first example above is the LCSH term. The other two terms are from sao (controlled Swedish subject heading system) and barn (Swedish children subject heading system). These three are using the same TOPIC_TERM Feminism, but they belong to different thesauri.
Warning
In existing systems, enabling this preference may require a reindex, and may generate new authority records if AutoCreateAuthorities is enabled.
Note
Support for multiple authority thesauri currently only works with ElasticSearch.
LinkerKeepStale
Default: Do not
Asks: ___ keep existing links to authority records for headings where the linker is unable to find a match.
Values:
Do
Do not
Description:
When set to ‘Do’, the linker will never remove a link to an authority record, though, depending on the value of LinkerRelink, it may change the link.
LinkerModule
Default: Default
Asks: Use the ___ linker module for matching headings to authority records.
Values:
Default
Retains Koha’s previous behavior of only creating links when there is an exact match to one and only one authority record; if the LinkerOptions preference is set to ‘broader_headings’, it will try to link headings to authority records for broader headings by removing subfields from the end of the heading
First match
Creates a link to the first authority record that matches a given heading, even if there is more than one authority record that matches
Last match
Creates a link to the last authority record that matches a given heading, even if there is more than one record that matches
Description:
This preference tells Koha which match to use when searching for authority matches when saving a record.
LinkerOptions
Asks: Set the following options for the authority linker ___
Important
This feature is experimental and shouldn’t be used in a production environment until further expanded upon.
Description:
This is a pipe separated (|) list of options. At the moment, the only option available is “broader_headings.” With this option set to “broader_headings”, the linker will try to match the following heading as follows:
=600 10$aCamins-Esakov, Jared$xCoin collections$vCatalogs$vEarly works to 1800.
First: Camins-Esakov, Jared–Coin collections–Catalogs–Early works to 1800
Next: Camins-Esakov, Jared–Coin collections–Catalogs
Next: Camins-Esakov, Jared–Coin collections
Next: Camins-Esakov, Jared (matches! if a previous attempt had matched, it would not have tried this)
LinkerRelink
Default: Do
Asks: ___ relink headings that have previously been linked to authority records.
Values:
Do
Do not
Description:
When set to ‘Do’, the linker will confirm the links for headings that have previously been linked to an authority record when it runs, correcting any incorrect links it may find. When set to ‘Do not’, any heading with an existing link will be ignored, even if the existing link is invalid or incorrect.
