Editorial Review
Bowker is the official ISBN agency for the United States and a cornerstone institution in the publishing industry. For anyone involved in book publishing — from independent authors to major publishing houses — Bowker provides essential services including ISBN registration, barcode generation, and bibliographic data management.
The website serves as both an information resource and a service portal. Publishers can purchase ISBNs, manage their title records, and access market research tools. The Books In Print database, maintained by Bowker, remains the authoritative reference used by libraries, retailers, and distributors worldwide.
While Bowker's services are reliable and industry-standard, the pricing for ISBNs has been a point of contention in the self-publishing community. Nevertheless, as the sole US ISBN agency, Bowker plays an indispensable role in the publishing ecosystem.
