Dear all, After installing the 3.00.00 beta version of the Koha, i've been trying to link the authorities records with the biblio records launching the link_bibs_to_authorities.pl script without success so far. I did some debugging at the koha-zebradaemon-output.log file and found out that the query looking for authorities matches didn't display any hits, because it was searching with the Match-heading Bib-1 attribute. Our authorities titles are stored in the Marc21 150$a field, that correspond with the Subject-topical-heading Bib-1 attribute, so i had to change in the Heading.pm file in the authorities method the Bib-1 attribute, suppress in the method _query_limiters the thesaurus and added terms, and add in the /etc/koha/zebradb/ccl.properties file the new Local-Use Authority Index of the Subject-topical-heading attribute. After all these changes, launching the link_bibs_to_authorities.pl script started to display results of heading changes and the zebraqueue was filled with biblio specialupdates operations. So i think this is the way how it has to be configured, at least for our authorities records. It worked for me. If anyone has a suggestion or believes that is a wrong procedure comments will be welcome. Thanks in advance and receive my best regards, Salva - ---- Salvador Zaragoza Rubio Departamento proyectos software C/ Garcilaso, 15 46003 Valencia Telf: 96 369 41 23 / 677 405 909 Fax: 96 369 34 39 www.masmedios.com
