As the U.S. ISBN Agency, Bowker receives the most authoritative title and publisher information available. Thorpe-Bowker, which is also the Australian ISBN Agency, provides Australian and New Zealand title data, while equally authoritative and un-biased book and serials title sources, including direct feeds from international publishers, provide Bowker with information worldwide. Bowker represents this book and serial title information to publishers, booksellers, and libraries globally. Bowker owns the most instantly recognizable and prevalent book and serials catalogs in the industry.

Leveraging this authoritative information, Bowker offers a wide range of specialized, and broadly-applicable, reference and reporting products and services.
