The Canadian ISBN Agency is the government agency in Canada responsible for issuing publishers an International Standard Book Number (ISBN) for their publications.
The International Standard Book Number (ISBN) is a system of numerical identification for books, pamphlets, educational kits, microforms, CD-ROMs and other digital and electronic publications.
Assigning a unique number to each published title provides that title with its own, unduplicated, internationally recognized identifier.
