Due to the high volume of ISBN requests being received, staff of the Legislative Library have created this FAQ. Links to further information on ISBN are included in these answers. Should you have any further questions, please contact us at ISN@ola.org.
An ISBN (International Standard Book Number) is a unique international identifier for publications. The ISBN program is international in scope and is directed in Canada by Library and Archives Canada (LAC). The Legislative Library assigns ISBNs to Ontario government documents on behalf of LAC. ISBNs are used to quickly and efficiently identify, order, distribute and retrieve publications.

ISBNs are unique numbers authorized by the International Organization for Standardization to identify publications.
The Government Publications Directive states that all publications, with certain exceptions, must have an ISBN.
ISBNs are a fast, effective way for OPS staff, researchers, scientists, and the public to find your publications in Publications Ontario catalogues, library catalogues, other bibliographic databases, and online search engines.
ISBNs are assigned to publications that are intended to be issued once. Revisions and new editions require a new ISBN. Examples: research and investigative reports, manuals, handbooks, informational fact sheets, maps, policy and planning documents.
If you plan to publish your document on a regular basis, such as an annual report, you require an ISSN.
Note: An ISBN may be assigned each year to an annual report to identify the specific year of the report. However, the annual report must be assigned an ISSN first.
No. Once an ISBN is assigned to a publication it can not be reused for another publication even if the original ISBN was assigned in error.
Yes. You can obtain an ISBN using the English title and qualifying it with the word “French.” Example: “Health care in long-term care facilities [French]”
No. There is no connection between the ISBN and copyright.
Yes. The number of copies published is not relevant to the ISBN assignment.
