Migrating Catalog Data
Understanding MARC files
We will need to convert MARC files exported from the legacy system, which have
an extension . mrc. Let's understand more about the structure of such files:
Records: Each MARC file will contain one or more MARC records. Each
MARC record contains bibliographic data and one or more holdings fields.
Bibliographic data: Each MARC record contains bibliographic data, such as
title, author, ISBN, or subject.
Holdings fields: Information on the physical copies
- such as library, barcode
number, shelving location, or collection code, is recorded in a holdings field.
A catalog record may have multiple holdings fields, one for each copy that is
available in the library.
Koha Holdings in tag 952
Koha keeps holdings data in tag 952. We will need to make sure that the records
in the import file have the data mapped to the 952 tag and to the corresponding
subfields under this tag.
You can view Koha's subfields under tag 952 in the MARC Bibliographic
framework section under Koha Administration.
