Hi! I want to import my newly created marc file into koha. Everything is imported successfully in the koha empty database and re-indexed. The problem is that I have duplicated titles. e.g: book1: introduction to koha nber of item: 1 book2: introduction to koha nber of item: 1 book3: introduction to koha nber of item: 1 but I want to have : book: introduction to koha nber of item: 3 If I set a matching rule, the import stalls after staging. Matching rule: Matching rule code : TITLE Description: 245$a Match threshold: 100 Match point: Search index: Title Score: 101 Matching component: Tag: 245 subfields: a offset: 0 length: 0 Normalization rule: TITLE Question: Is it possible to do this in koha ? for each duplicate marc record : Koha does not add it but instead add the item info under existing record increase the number of item under the duplicate record. Should I add only record info and add items info manually ? But with more than 40 000 books it will be a nightmare Thanks for helping !
