  • Elimination of Record Length Checks in WorldCat.
  • Correction of Relationship Rules for Local Holdings Records (LHRs).
  • Correction of Validation Rules for Bibliographic Field 041.
  • Correction of Repeatability for Bibliographic Field 691 Subfield $b.

New features and enhancements

OCLC-MARC Validations of New MARC Codes Announced October 26, 2018

Full details of the new MARC Codes that were announced by the Library of Congress on October 26, 2018, are available in the LC Technical Notice (October 26, 2018).

Important Note: Although the Language Code and Term Source Code “austlang” is now valid in Bibliographic field 041 subfield $2, it was discovered that validation does not correctly recognize non-MARC language codes in the alphabetic subfields. A fix to this is being worked on and is expected to be installed in May 2019. Thank you for your patience and understanding.

Elimination of Record Length Checks in WorldCat

Bibliographic records, Local Bibliographic Data records (LBDs), Local Holding Records (LHRs), and Authority records in WorldCat no longer have restrictions on length.

Bug fixes

Correction of Relationship Rules for Local Holdings Records (LHRs)

Before the changes to validation, LHRs coded Encoding Levels 4 or 5 were generating validation errors associated with incorrect relationships to any one of several fields in the 85X, 86X, or 87X ranges.

After the changes to validation, LHRs coded Encoding Levels 4 and 5 correctly validate with any one of several fields in the 85X, 86X, or 87X ranges.

Correction of Validation Rules for Bibliographic Field 041

Before the changes to validation, MARC Language Codes “mul”, “sgn”, “und”, and “zxx” could not be used in any of the alphabetic subfields in Bibliographic field 041.

After the changes to validation, MARC Language Codes “mul”, “sgn”, “und”, and “zxx” can once again be used in any of the alphabetic subfields in Bibliographic field 041.

Correction of Repeatability for Bibliographic Field 691 Subfield $b

Before the changes to validation, Bibliographic field 691 subfield $b was not repeatable.

After the changes to validation, Bibliographic field 691 subfield $b is repeatable.

Allowing the Change of an Invalid Encoding Level Value to a Valid ELvl Value

Before the changes to validation, institutions working to clean up dark/staged records from Data Ingest processing were unable to correct an invalid Encoding Level (Leader/17) value to a valid value. Changes were allowed only from one valid value to another valid value.

After the changes to validation, institutions working to clean up dark/staged records from Data Ingest processing are now able to correct an invalid Encoding Level (Leader/17) value to any valid value that is allowed by their authorization level.
