Call number fields
This section explains printing of call numbers in the following call number fields:
Your profile specifies each holding library as using Library of Congress (LC), Dewey, National Library of Medicine (NLM), Government Document (Gov Doc) or Library and Archives Canada (NLC) call numbers. The call number selected to print depends on the class scheme of the holding library in field 049 (Local Holdings) and the default call number priority for that scheme.
The print program checks for field 099, then field 098. If neither is in the record, the print program follows the priority list, according to the holding library's classification. When the print program finds a field in the default list, it prints that call number. For example, if the record does not contain field 099 or field 098, the print program selects field 090 for an LC holding library. If no field 090 is present, it selects field 050.
If the print program does not find a field that is on the priority list, it generates a unit ( zc) card. If the record contains two or more of the same field (e.g., an LC holding library with two 099 fields), it selects the field with the highest line number.
|Your profile determines how the print program parses LC ( field 050 and field 090) and Dewey ( field 092) call numbers for printing.|
The appearance of the data at the time of produce determines how the print program parses NLM ( field 060 and field 096), Library and Archives Canada ( field 055) and local or other ( field 098 or field 099) call numbers for printing.
Government Document numbers ( field 086) always print on one line.
For all call numbers, your profile specifies the position in which the call number prints relative to stamps (automatic stamps and input stamps) and oversize designations.
|Empty call number fields|| |
The system displays an empty call number field each time your retrieve a record. Your authorization number's default classification scheme determines which field the system displays.
The system-displayed empty call number field does not limit your selection of call numbers for card production. For example, if you have an LC authorization number and you are cataloging an item for a non-LC holding library, enter a non-LC call number in the empty field 090, then change the field 090 to the appropriate call number field (i.e., field 092, field 098 or field 099).
|Call number suppression (x-suppression)|| |
You may want some card sets to print with no call number or with other information in the call number area.
To produce cards without call numbers, enter "nonprinting" data (usually x) in the local call number field for the holding library's default classification scheme. The x in the local call number field indicates to the system that no call numbers should be printed. Your profile specifies the character you should use for call number suppression.
|Guidelines: call number suppression|| |
Use the following guidelines:
|Master record|| |
When you input a new record, the following call number fields do not become part of the master record, except as noted:
|Unit (zc) cards|| |
Cards in zc packs are errors in card production. These cards are single cards printed instead of the full set of cards. The following errors usually cause the unit cards:
|Accessions lists|| |
The Accessions List Service selects the call number according to the classification scheme (e.g., LC, Dewey, NLM, Government Document or local call numbers) in your profile. You cannot select Canadian call numbers for use in OCLC Accessions Lists.
|OCLC-MARC records|| |
OCLC-MARC records carry all call numbers that were present in the record at the time of produce, update or export.
|Call numbers in label displays|| |
The system selects a call number for label display based on the default classification scheme of your authorization number and the following label display priority:
