The Vaari-Finna operates first and foremost as a tracking database for ILL services, so its own primary cataloguing standards are low; bibliographic records do not contain classification, keywording or serial numbers. Most records copied from elsewhere, however, are at the level required in local or national bibliographies.

Primary cataloguing is the very domain in which the NRL has had a specific role in Finland. The National Repository Library is one of the main producers of bibliographic data for the Union Catalogue of Finnish University Libraries (called Melinda), so its contribution to the attainability and availability of acquisitions in our country is significant.

Cataloguing format is MARC21.
