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.
Observera
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 4
Varning
The relationships must be bidirectional, meaning the broader term must reference the narrower term and the narrower term must reference the broader term.
AuthorityControlledIndicators
Asks: Use the following text to edit how authority records control indicators of attached biblio fields (and possibly subfield $2). Lines starting with a comment symbol (#) are skipped. Each line should be of the form: (marc21|unimarc), tag, ind1:(auth1|auth2|some_value), ind2:(auth1|auth2|thesaurus|some_value). Here auth1 and auth2 refer to the indicators of the authority record, tag is a biblio field number or an asterisk (*), and some_value is a fixed value (one character). The MARC21 option thesaurus refers to indicators controlled by authority field 008/11 and 040$f.
Description:
Used when merging authorities.
Controls how the indicators of linked authority records affect the corresponding biblio indicators. Currently, the default value is fine-tuned for MARC21 and copies the authority indicators for UNIMARC.
For example, a MARC21 field 100 in a biblio record should pick its first indicator from the linked authority record. The second indicator is not controlled by the authority. This report supports such MARC conventions.
AuthorityMergeLimit
Asks: When modifying an authority record, do not update attached bibliographic records if the number exceeds ___ records. (Above this limit, the merge_authority cron job will update them.)
Default: 50
Description:
This system preference determines the maximum number of bibliographic records that can be updated when an authority record changes.
This helps prevent overusing resources if an authority record is linked to many bibliographic records.
Make sure to enable the merge_authority cron job to catch the updates that wouldn’t otherwise be transferred to bibliographic records.
AuthorityMergeMode
Default: loose
Asks: When updating biblio records from an attached authority record (”merging”), handle subfields of relevant biblio record fields in ___ mode. In strict mode subfields that are not found in the authority record, are deleted. Loose mode will keep them. Loose mode is the historical behavior and still the default.
Values:
loose
strict
AutoCreateAuthorities
Asks: When editing records, ___ authority records that are missing.
Default: don’t generate
Values:
don’t generate
generate
Description:
This system preference allows you to decide if Koha automatically creates new authority records from the bibliographic records.
Varning
RequireChoosingExistingAuthority must be set to ”don’t require”, otherwise this system preference has no effect.
If this is set to ”don’t generate”, and catalogers enter uncontrolled terms in controlled fields, Koha will not generate matching authority records.
If set to ”generate” (and RequireChoosingExistingAuthority is set to ”don’t require”), Koha will automatically create authority records for headings that don’t have any authority link when saving a bibliographic record.
DefaultAuthorityTab
Version
This system preference was introduced in version 23.11 of Koha.
Asks: When viewing authority details default to the ___ tab. If the selected tab does not exist, the view will default to the first tab.
Values:
0XX
1XX
2XX
3XX
4XX
5XX
6XX
7XX
8XX
9XX
Default: 0XX
Description:
This system preference allows the library to choose which tab is presented first when viewing an authority record.
By default, the ”0” tab, containing all 0XX MARC fields, is selected when first viewing an authority record.
If the selected tab doesn’t exist for that particular authority record, the first tab (usually tab ”0”), will be selected by default.
GenerateAuthorityField667
Asks: Use the following text as default value for the 667$a field of MARC21 authority records: ___
Default: Machine generated authority record
Description:
This system preference is used when Koha automatically creates authority records when RequireChoosingExistingAuthority is set to ”don’t require” and AutoCreateAuthorities is set to ”generate”.
Enter the text you want to use in the 667$a field.
Observera
This system preference is only used when marcflavour is set to MARC21.
GenerateAuthorityField670
Asks: Use the following text as default value for the 670$a field of MARC21 authority records: ___
Default: Work cat.
Description:
This system preference is used when Koha automatically creates authority records when RequireChoosingExistingAuthority is set to ”don’t require” and AutoCreateAuthorities is set to ”generate”.
Enter the text you want to use in the 670$a field.
Observera
This system preference is only used when marcflavour is set to MARC21.
MARCAuthorityControlField008
Default: || aca||aabn | a|a d
Asks: Use the following text for the contents of MARC21 authority control field 008 position 06-39 (fixed length data elements).
Viktigt
Do not include the date (position 00-05) in this preference, Koha will calculate automatically and put that in before the values in this preference.
Description:
This preference controls the default value in the 008 field on Authority records. It does not effect bibliographic records.
RequireChoosingExistingAuthority
Asks: When editing records, ___ catalogers to reference existing authorities.
Default: don’t require
Values:
don’t require
require
Description:
This system preference determines whether or not catalogers can type into authority controlled fields.
If set to ”don’t require”, catalogers can manually enter uncontrolled terms into controlled fields
If set to ”require”, authority controlled fields will be locked, forcing catalogers to search for an authority.
If set to ”require”, it will block AutoCreateAuthorities. Authorities will have to be catalogued manually (or imported).
UNIMARCAuthorityField100
Default: afrey50 ba0
Asks: Use the following text for the contents of UNIMARC authority field 100 position 08-35 (fixed length data elements).
Viktigt
Do not include the date (position 00-07) in this preference, Koha will calculate automatically and put that in before the values in this preference.
Description:
This preference controls the default value in the 100 field on Authority records cataloged in UNIMARC. It does not effect bibliographic records.
UseAuthoritiesForTracings
Default: Don’t use
Asks: ___ authority record numbers instead of text strings for searches from subject tracings.
Values:
Don’t use
Search links look for subject/author keywords (example: opac-search.pl?q=su:Business%20networks)
Use
Search links look for an authority record (example: opac-search.pl?q=an:354)
Description:
For libraries that have authority files, they may want to make it so that when a link to an authorized subject or author is clicked on the OPAC or staff client it takes the searcher only to a list of results with that authority record. Most libraries do not have complete authority files and so setting this preference to ’Don’t use’ will allow searchers to click on links to authors and subject headings and perform a keyword search against those fields, finding all possible relevant results instead.
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.
Observera
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.
Varning
In existing systems, enabling this preference may require a reindex, and may generate new authority records if AutoCreateAuthorities is enabled.
Observera
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 ___
Viktigt
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.
