About the National Union Catalogue
The National Union Catalogue (NUC) reflects the collections of New Zealand libraries and the New Zealand National Bibliography. It is a central database of catalogue records to which New Zealand libraries contribute bibliographic records and holdings information. It is also used as a source of catalogue records by libraries throughout New Zealand. Its economic value has been documented.
- 280 member New Zealand libraries
4 million bibliographic records
13 million holdings records
Contributing to the NUC
Libraries can contribute to the NUC by directly adding cataloguing information using Te Puna WebCat and the Te Puna Cataloguing Client. Some libraries provide a file of records which are batch loaded to the NUC. And some New Zealand libraries use OCLC Cataloguing Services and these records are supplied to us as batch loads from OCLC.
Library holdings in the NUC are sent onto OCLC for inclusion in WorldCat. Errors for the holdings in the National Union Catalogue can be reflected in WorldCat.

One catalogue record for one bibliographic entity
The NUC strives to contain one catalogue entry for each bibliographic item or a group of items with similar bibliographic characteristics (e.g. multi part work) through de-duplicating the catalogue entries for each New Zealand library catalogues. There are some issues maintaining equivalence for library holdings in individual New Zealand libraries catalogues and the National Union Catalogue. These issues can be caused by human and machine error.
