The British Library is a registration agency for the following identifiers: DOI via DataCite, ISSN, ISNI, ISIL, and MARC organization codes.
Our identifier services enable the unique identification of:
- datasets for commerce, research, interoperability and discovery
- new or changed titles of serials published in the UK
- persons and corporate bodies
- UK libraries and related organisations.
DOI: Digital Object Identifier
ISSN: International Standard Serial Number
The ISSN is the international Standard Serials Number (ISO 3297) that uniquely identifies serial publications.
The British Library hosts ISSN UK. We are the national centre responsible for assigning ISSN to serials published in the United Kingdom. The ISSN International Centre provides information on other ISSN National Centres.
The ISNI is the International Standard Name Identifier (ISO 27729) for identifying the millions of contributors to creative works and those active in their distribution, including researchers, inventors, writers, artists, visual creators, performers, producers, publishers, aggregators and more.
The British Library is a Registration Agency for the ISNI. We are working with partners in the cultural, research and publishing communities to assign ISNIs to persons and organisations. We're also integrating ISNIs in our cataloguing and authority workflows.
The Library is assigning ISNIs to all new authors in our e-theses online service, EThOS.
In April 2021, the Library launched the ISNI Portal. It enables users to register new ISNIs as well as add data to their own ISNI records.

ISIL: International Standard Identifier for Libraries and related organisations
The ISIL is the International Standard Identifier for Libraries and related organization (ISO 15511). An ISIL can be assigned to a library or related organisation. An ISIL can also be assigned to sub-units of an organisation. ISIL is a requirement of the UK Data Model for implementation of ISO 28560/2 RFID in libraries -- Part 2: Encoding of RFID data elements based on rules from ISO/IEC 15962.
MARC organization code
MARC organization codes (formerly known as NUC codes) represent names of libraries, other kinds of organisations or sub-units of organisations that need to be identified in the bibliographic environment.
