Dear friends, We have recently upgraded to koha 3.10. After importing our catalog and authority records we have used link_bibs_to_authorities.pl script to link them. During the process I was frequently (once per 1000 record) seeing this error on the console. ----- Auth error: Query term includes characters that do not translate into the target character set (1072) Bib-1 ----- However, when the process is over it seems that authorities were linked to the biblios. The message below appears in the console. ---------------------------------------------------- Bib authority heading linking report ======================================================= Linker module: C4::Linker::Default Run started at: 02/04/13 10:40:18 Run ended at: 02/04/13 11:16:16 Total run time: 2157486 ms Number of bibs checked: 255350 Number of bibs modified: 0 Number of bibs with errors: 0 Number of headings linked: 44199 Number of headings unlinked: 722664 Number of headings fuzzily linked: 0 --------------------------------------------------------- Moreover, when i go to specific records in the sub field 100 $9 I can see the appropriate authority code. Yet, when I search for the authority in the *Used in* column *0 records* is written. What is more, I was told that starting from this version we can search for the records using the *authority 400 a$* field instead of the author name just preliminary turning on syspref "IncludeSeeFromInSearches". Unfortunately, this feature worked neither. Any ideas or suggestions? Thanks in advance, Haik
