Thanks to Everyone who replied - the system is now coming together . I upgraded to 3.00 and imported the database, and followed the processes outlined in the http://wiki.koha-community.org/wiki/Upgrading_2.2 document. I have two remaining issues: In the Mysql database (prior to running any scripts etc), the call numbers seemed to be in the 082 field, judging by the contents of the `tag` and `subfieldvalue` fields of the `marc_subfield_tag' file, not in the `itemcallnumber` field of the `items` file. After running the process detailed in the upgrade document, the call numbers dont' appear in the catalogue. They seem to have been moved to a file ' temp_upg_biblioitems_call_num. Any advice on how I can get these call numbers indexed properly? Also, when I try to add an item, the process fails with an error. In the error log, it refers to the record wrapper missing at /usr/local/share/perl/5.10.1/MARC/file/XML.pm. Thanks again, Peter Thompson Whenever I add an item Peter Thompson Database Administrator Information Technology & Communications Unit
