Definition

 Data of local interest. Field 910 is not part of the standard MARC format. It does not become part of the master record. Field 910 is stored in archive records, exported records and OCLC-MARC records. Use field 910 for a specific item (e.g., accession number) at the time of cataloging.

Printing

 User-option data prints on those cards specified in your profile. User-option data prints on the bottom line of the card, to the left of the rod hole.
 

Only the first 21 characters in field 910 print, but archive records, exported records and OCLC-MARC records retain the entire field (up to 1,230 characters).

User-option data details (e.g., the OCLC control number) may be printed automatically. Data profiled for automatic printing does not appear online and is not stored in archive records, exported records or OCLC-MARC records. When cards are printed, data entered online in a 910 field overrides the data profiled for automatic printing.
