Bibliographic Services

DataNZ has extensive experience in library cataloguing and other bibliographic services.

We can retro-convert card catalogues to MARC21 using a framework in an XML environment. This framework was developed by the US Library of Congress and is available at The content of data elements in MARC records is defined by standards such as AACR (Anglo American Cataloguing rules), ISBD(G): General International Standard Bibliographic Description and others.

Apart from MARC, we can convert to Metadata Object Description Schema (MODS) which is a schema for a bibliographic element set that may be used for a variety of purposes, and particularly for library applications.

We also have the expertise in EAD (Encoding of Archival Descriptions) - a standard for describing collections held by archives and special collections, similar to the MARC standards for describing regular books. Such a standard enables museums, libraries, and manuscript repositories to list and describe their holdings in a manner that would be machine-readable and therefore easy to search, maintain, exchange.

We have also developed complex metadata coding and capture software for catalogue conversions.
