https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=30280 Bug ID: 30280 Summary: Koha does not currently support authority posts with common subject headings from different thesaurus Change sponsored?: --- Product: Koha Version: master Hardware: All OS: All Status: NEW Severity: enhancement Priority: P5 - low Component: MARC Authority data support Assignee: koha-bugs@lists.koha-community.org Reporter: frank.hansen@ub.lu.se QA Contact: testopia@bugs.koha-community.org Consider this three following examples 650 _ 0 $a Feminism 650 _ 7 $a Feminism $2 sao 650 _ 7 $a Feminism $2 barn The first example above is the LCSH term. The two other sao (controlled Swedish subject heading system) and barn (Swedish children subject heading system). These three using basically the same TOPIC_TERM Feminism but they belongs to different thesaurus. According to https://www.loc.gov/marc/authority/ (Library of Congress), subject heading thesaurus/system is specified in 008/11 in the authority record. When other thesaurus/system is used, the value of 008/11 is "z" (Other) and the convention used is marked up in field 040$f. But Koha currently not seems to support the use of different thesaurus. The script link_bibs_to_authorites.pl will treat authority records with the same TOPIC_TERM from different thesaurus as duplicates and will not be able to link the subject heading to its corresponding authority record. We would like if Koha could let authority records from different thesaurus co-exist in Koha and "learn" Koha how to distinguish between them. -- You are receiving this mail because: You are the assignee for the bug.
