Had difficulty with my MARC check after installing Koha. Used Jason Ronalio's suggestion and found that one of the item fields was mapped to a 942 subfield. Next MARC Check was clear. Thanks for the help! [Also check your MARC to koha database links. Use the dropdown to get to items. Make sure that the nonMARC fields are mapped to a 952 subfield] Scott Manteuffel Eaton Academy Eastpointe, MI
