• Indicators - both undefined, each contains a blank

When to use field 914

• Use for records that are so brief when created that they will cause duplicates in OCLC
  • Examples:
    • Bibliographic record created for acquisitions purpose that lacks a publication date
    • Acquisitions records created for video where format is uncertain (Blu-Ray vs. DVD, for example)

      • Some libraries may have incorrect or missing coding for certain media, which could cause duplicate records to be created during Data Sync.  

      • Example: MMS ID 99156101146203941
• Use for records representing equipment or other items that should not be reported to OCLC (e.g. loaner laptops, headphones, etc.).
  • Examples:
    • MMS ID 990087259580203941
• Use for special collectionsmaterials not yet processed that should not yet be reported to OCLC or ArchiveGrid.

• Some Import Loads

  • Vendor import loads may be given this field due to insufficient bibliographic information or incorrect coding.  These decisions are made by the team working on the import.

• Use for records where experience suggests that preliminary data (e.g. from a particular vendor) is often unreliable, potentially leading to duplicates in OCLC. Example: frequently inaccurate publication dates. 

...

• Previous practice mandated placement of the 007 for audio/visual materials in the holdings record.  When updating one of these legacy records, please remove the 007 from the holdings, since conflicts between the holdings and bibliographic 007 might cause a duplicate in OCLC. The 914 field would not be used in these cases.
