050-099  Introduction to Call Numbers

Call number fields

This section explains the use of call numbers in the following call number fields:

Your Connexion authorization or Record Manager account role is profiled as using either Library of Congress (LC), Dewey Decimal Classification (DDC), Government Document (GovDoc), Library and Archives Canada (LAC), National Agricultural Library (NAL), National Library of Medicine (NLM), or Universal Decimal Classification (UDC) call numbers.

Connexion. The system selects a call number for label displays based on the default classification scheme of your authorization number and the following label display priority:

Record Manager. The system selects a call number for label displays based on the default classification scheme of your account role and the following label display priority:

The system displays an empty call number field each time you retrieve a record from WorldCat. The default classification scheme associated with your Connexion authorization or Record Manager account role determines which field the system displays.

If your authorization number or account role defaults to LC classification, the system displays field 090. If your authorization number or account role defaults to DDC, the system displays field 092 and so forth.

The system-displayed empty call number field does not limit your selection of call numbers for label displays. For example, if you have an authorization or account role with an LC classification default and you are cataloging an item that requires a non-LC call number, then change the field 090 to the appropriate call number field, e.g., field 099.

When you input a new record, the following call number fields do not become part of the WorldCat record, except as noted:

Certain classification choices are recognized to be local decisions. Multiple call numbers in the same classification scheme in the WorldCat record may be appropriate and are allowed in these circumstances:

• For resources in monographic series, a classed together call number and a classed separately call number exist in the same record
