CODOC Call Numbers

What is CODOC?

  • The CODOC classification system is used to classify many of the print government publications. The call numbers are a combination of letters and numbers and are arranged on the shelves alphabetically by issuing country.

  • At the J.N. Desmarais Library, the Government Publications collection is located on the 3rd floor.

  • Publications with CODOC call numbers are listed in the Catalogue. It is important to note the EXACT call number including all spaces.


Reading CODOC Call Numbers

Spaces in CODOC call numbers are used to indicate the end of each line in the call number.

For example, CA2ON H90 99S21 will appear on the publication as shown below:


CA - identifies the country (Canada);

2 - identifies the government level within the country (provincial);

ON - identifies the province (Ontario)


H - identifies the department (Ministry of Health);

90 - identifies the branch (Substance Abuse Bureau)


99 - identifies the year of the publication (1999);

S21 - unique document identifier


*** Additional Information***

After 1999, the date field changed to 4 digits: i.e CA1 HW245 2000P23 where 2000 identifies the year of publication.
