Requirements for records

OCLC database specialists thoroughly evaluate records submitted by vendors. OCLC loads vendor records into WorldCat via offline batchload process if the following conditions are met:

  • The records do not match existing records
  • Fewer than 2% of the records contain machine-detectable errors in MARC coding
  • The records adhere to U.S. standards for cataloging, including both descriptive cataloging and forms of headings
  • The records meet OCLC minimum (K-level) standards for completeness
  • The records are in MARC 21 format

About WorldCat record matching

Record type Matches a WorldCat record? What happens
Publisher or material vendor Yes OCLC adds a vendor-specific 938 field to the master record; the vendor's OCLC symbol is set
Publisher or material vendor No New WorldCat record is created with a 938 field; the vendor's OCLC symbol is set
Bibliographic record vendor N/A OCLC does not add the vendor-specific 938 field, nor does it set the vendor's OCLC symbol

About the 938 field

The 938 field in MARC records contains vendor-specific ordering data, defined as follows:

Code Definition
Subfield codes Both indicators are blank
$a Full name of vendor Supplied by OCLC
$b OCLC-defined identifier for vendor Supplied by OCLC. These identifiers are used for indexing purposes and should not be confused with OCLC institution symbols. (See current identifiers below.)
$c Terms of availability Purchase price
$n Vendor control number A unique number assigned by the vendor to identify the item for offline ordering
$s Vendor status Indicates if the item is backordered, out-of-print, not yet published, etc.
$z Note General notes field in which a vendor can include order information specific to the item

To facilitate searching for vendor records in WorldCat, OCLC indexes field 938 subfields $a and $b.
