ISBNs and Catalogue Numbers
The Depository Services Program (DSP) is responsible for assigning ISBNs to all book-like products (monographic or non-serial publications) published by the Government of Canada. The DSP also assigns Government of Canada Catalogue Numbers to all Government of Canada publications, both monographic and serial. Publications are defined as all products, regardless of publishing medium, containing information for public consumption or for limited circulation. The application of these unique identifiers is mandatory under the Communications Policy of the Government of Canada.
