Authority Control

The British Library uses the Library of Congress / NACO Authority File (LC/NAF) to control the forms of names in its catalogues. The British Library is one of the major contributors of authority data to the Name Authorities Co-operative (NACO) component of the Program for Cooperative Cataloging.

ISO 27729:2012 International Standard Name Identifier (ISNI)

The British Library was part of the committee which developed ISNI and provides one of the directors of the International Agency (ISNI-IA) acting as the representative of the Conference of European National Librarians (CENL), one of the founding members of the consortium that established the ISNI-IA.

In 2006, the British Library became a Registration Agency for the ISNI.


The British Library was a partner in the Names Project, which was working to uniquely identify individuals and institutions involved in research in the United Kingdom. The Project was funded by JISC and led by MIMAS.
