Catalogue Filing and Numbering

As with all publications, multiple formats must be assigned an International Standard Number and copies sent to the Depository Services Program (DSP).

DSP Copies:

Many departments are not aware that they must file copies of every publication with the Depository Services Program. The DSP maintains a large library of government publications with the primary objective to ensure that Canadians have ready and equal access to federal government information. The DSP distributes government publications to a large network of libraries and institutions. The number of publications required for the Program varies with the language, subject and intended audience of the publication.

Numbering:

The DSP is also contacted to obtain a Government of Canada Catalogue Number and ISBN (International Standard Book Number) or ISSN (International Standard Serial Number).

Each format requires a separate number. ISBN's are typically used for books while ISSN's are used for periodicals such as newsletters.
