ISBN requests

Bien que les édifices de BAnQ ouvrent progressivement, le service de l’ISBN sera offert à distance uniquement pour le moment. Par conséquent, les demandes reçues par courriel à isbn@banq.qc.ca et isbngouv@banq.qc.ca recevront une réponse dans le délai habituel. Par contre, si vous téléphonez, il faudra laisser un message sur la boîte vocale, car il n’y aura pas de service téléphonique direct. Merci de votre compréhension.


ISBN's and Bibliothèque et Archives nationales du Québec

The ISBN (International Standard Book Number) is an international numbering system standard for books, under which a digital code is used to identify each title or edition of a title issued by a same publisher. ISBNs facilitate the various management operations of all parties in the book field (libraries, bookstores, publishing houses, distributors, etc.) and constitute accurate search keys that are useful for locating publications in data banks.

Bibliothèque et Archives nationales du Québec (BAnQ) acts as an official representative of the Agence francophone pour la numérotation internationale du livre with Canadian French-language publishers. It assigns an ISBN with the identifier 2, signifying the French-language group, to all publishers who apply for one and sends them, free of charge, a block of numbers corresponding to their needs. It also coordinates the assignment of ISBNs reserved for Québec government departments and agencies.

In addition to assigning ISBNs, BAnQ also keeps an address list of participating publishers. The regularly updated Bottin des éditeurs francophones canadiens, is available online, free of charge. Canadian French-language publishers already registered can send in notifications of any change in their contact information by email.

To learn more about the ISBN system, its benefits for publishers, the types of materials covered and the rules for assigning ISBNs, read the ISBN's users' manual [PDF file - 2.23MB - in French only] or contact BAnQ's ISBN agency.
