Hi, My name is Prawesh Shrestha from Nepal. I am working as Project Engineer in Young Innovation Pvt. Ltd., a software company. My company had installed koha in a local university library. I am looking after it but not as developer more as a koha's features user. Right now, I am looking after the importing of catalog in koha from WinIsis. Before that, more than half data had been imported and new data had also been entered. There are more data from Winisis to be migrated but we are not exactly in position to know the remaining data to be imported. So we have full data of which some had been imported. So I am trying to import the leftover using "Matching Rules". I made new matching rules matching titles. Although it works, few of the data are duplicated. I went through manual and a book "Koha 3 Library Management System". However, I can get full understanding of matching rules. Is there anyway I can understand matching rules in more depth or technique to avoid the duplication. I hope you understand what I want to know.
