Nielsen Book


Nielsen Book has four key brands: Registration Agencies, BookData, BookNet and BookScan.

The Nielsen Book Registration Agencies provide a range of standard identifiers to English-language publishers for use in the international supply chain.

The ISBN Agency issues publisher prefixes and ISBNs to publishers based in the UK and the Republic of Ireland. The SAN Agency is administered on behalf of BIC and assigns Standard Address Numbers and Global Location Numbers to organisations in any country except USA, Canada, Australia and New Zealand. The ISTC Agency assigns International Standard Text Codes to authors, publishers and other authorised representatives who wish to register textual works. The agencies also provide advice and guidance on making the most of these identifiers.
