Hello, We are trying to import authorities and biblios from an old system into koha but we've run into several problems. There is another recent thread related to authorities import but I don't think the problems are related. Our problem is as following. We tried to import authorities from a marc file with the following format: LDR 00119nx a22000613 009 HERBERT, FRANK 200 _aHERBERT _bFRANK 801 0 _aRO _bARBJ using the bulkauthimport.pl tool. The tool gives no error and 1 item seems imported. However we can see nothing in the interface. I also tried to use the stated import from the interface but after some research I found a thread saying it is only used for biblios and not authorities. Upon some digging we noticed the following warn in zebraidx: 22:24:10-01/03 zebraidx(1209) [warn] /usr/share/koha325bjarad/etc/zebradb/authorities/etc/dom-config-marc.xml: stylesheet authority-zebra-indexdefs.xsl not found in path /usr/share/koha325bjarad/etc/zebradb/authorities/etc:/usr/share/koha325bjarad/etc/zebradb/etc:/usr/share/koha325bjarad/etc/zebradb/marc_defs/unimarc/authorities:/usr/share/koha325bjarad/etc/zebradb/lang_defs/en:/usr/share/koha325bjarad/etc/zebradb/xsl Is there a xsl for unimarc? I don't know if this is causing the problem. The entries are imported and not indexed? Or they are not even imported. Is the marc format wrong for unimarc? Also it seems that the unimarc install only creates the default authority type. In marc21 there are several created. Can this be a cause of problems? Also, again unrelated to the previous problems when searching for authorities from the create biblio page the following error occurs: Premature end of script headers: auth_finder.pl, referer: http://10.10.0.12:8002/cgi-bin/koha/authorities/auth_finder.pl?authtypecode=PER&index=tag_700_subfield_a_470688_260229&value_main= It seems there is no luck for authorities today. Thank you for any help. Kind regards, Len www.len.ro
