In addition to regular updates, bulk data files may also be provided to:
- Customers wishing to undertake an offline retrospective conversion of their catalogue and requiring a complete back file of the national bibliography
- Offer customers a complete refresh of the dataset following a significant change (e.g. MARC format, adoption of new cataloguing rules, significant change to identifiers etc)
- Offer complete datasets in an alternative format to non-library users (e.g. in Dublin Core, RDF, ‘flat file’ etc.) as part of an ‘open data’ initiative.
