> The Publications New Zealand Metadata Dataset contains bibliographic records of books, periodicals, films, music and other material published in New Zealand, or with a significant New Zealand content. The records were originally created by the National Library of New Zealand, with a small number of contributions from the libraries of New Zealand through Te Puna.
> Bibiliographic records and book cover images used under licence by the National Library have been excluded from this dataset release.
> The current dataset was extracted on 22 February 2011, and contains approximately 350,000 records. Records are provided in 2 formats: MARC and MARCXML - both being library catalogue record standards.
The each zip archive actually contains a README file along the data in gzipped format. Therefore, you will need a decompression tool that supports both formats.
