Call numbers used in the Government Documents Collection are based on a numbering system called the CODOC system that identifies the government body that has issued a publication.
Structure of CODOC Numbers
CODOC numbering indicates country or international organization, level of government, the agency responsible for the document, the date of publication (if a single work) and a title indicator.
The language of the document text is also shown at the end of the call number line but does not appear on the call number label on the book. Example: ENG = English; FRE = French; EXF = English and French
Works that are published on a continuing basis under the same title (serials) do not have a date of publication in the CODOC number and are shelved before single works that have a date of publication. Example shelf ordering:
Serial: World development report UN9 MG W53 .ENG
Monograph: A guide to the World Bank UN9 MG 2003.G78 .ENG
Some frequently used country and international organization codes:
|Code||Country or International Organization|
|CA1||Canada (federal government)|
|CA2||Canada (provincial governments); CA2ON = Ontario|
|US1||United States (federal government)|
|UN1-UN8||United Nations and subordinate agencies|
|UN9||Organizations part of the United Nations System; UN9 ES = UNESCO|
|ZZ||Non-UN international organizations; ZZ ECA = OECD|
The spaces in the call number are used to indicate the end of each line in the call number, when it is typed vertically on a call number label. Example:
|Floor 1 Documents DDV||CA1 EA200 86.N55 .ENG||LIB'Y USE ONLY|
The above catalogue record matches the call number label:
Location Codes in the Documents Collection
When noting a government document call number, it is extremely important to include the three-letter location code (found in the LOCATION box after "Floor 1 Documents" in the catalogue record) because the Documents Collection is divided into many parts.
|DDV & DDV2||General print material|
|MDE||Digital format documents (CD-ROMs)|
|STF||Documents in storage in the Storage Facility - available by request|
Note: Some titles may be in more than one location.
