Release Date: February 24, 2022
This release of changes to WorldCat Validation involves the following new features, enhancements, and bug fixes.
These enhancements and fixes are the result of announcements of new MARC elements and codes by the Library of Congress as well as feedback and requests from members of the OCLC community.
You may now use all new MARC Codes announced by the Library of Congress in the following LC Technical Notices:
The following source code has been added to the Cartographic Data Source Codes list for usage in appropriate fields and elements.
The following source code has been added to the Description Convention Source Codes list for usage in appropriate fields and elements.
The following source codes have been added to the Genre/Form Code and Term Source Codes list for usage in appropriate fields and elements.
The following source code has been added to the Name and Title Authority Source Codes list for usage in appropriate fields and elements.
The following source codes have been added to the Standard Identifier Source Codes list for usage in appropriate fields and elements.
The following source codes have been added to the Subject Heading and Term Source Codes list for usage in appropriate fields and elements.
Two new ISSN Centre Codes have now been validated for use in Bibliographic field 022 (International Standard Serial Number) subfield $2.
You may now begin to use the following changes to Bibliographic elements implemented as part of OCLC-MARC Bibliographic Update for February 2022, based on the MARC 21 Bibliographic format changes announced in MARC 21 Bibliographic Update No. 33 (November 2021):
You may now begin to use the following changes to Authority elements implemented as part of OCLC-MARC Authority Update for February 2022, based on the MARC 21 Authority format changes announced in MARC 21 Authority Update No. 33 (November 2021).
Note: These changes apply only to the OCLC-MARC Authority validation rule set that includes all valid elements of MARC 21 Authority Format and cannot be used in the LC/NACO Authority File.
Name Authority Cooperative (NACO) participants should not use these authority format changes in the LC/NACO Authority File at this time. The Library of Congress and OCLC will announce the implementation of these elements for use in name and subject authority records in the LC/NACO Authority File at a future date.
There are no changes to the MARC 21 Format for Holdings Data for Update No. 33 (November 2021) resulting from proposals that were considered by the MARC 21 community since the publication of Update No. 32 (June 2021).
In accordance with the announcement “Implementation of History Notes in Field 688 in Authority Records for LCSH, LCGFT, LCDGT, LCMPT, and CYAC” issued on 2022 February 22 by the Library of Congress Policy, Training, and Cooperative Programs Division, LC will begin to use Authority field 688 (Application History Note) in records for the following vocabularies:
Field 688 and its subfield $a are now valid in the rule set for Library of Congress Subject Authorities. Field 688 will begin to appear in LC distributed subject authority records no earlier than April 4, 2022.
In Bibliographic field 072 (Subject Category Code), the relationship between Second Indicator value “7” (Source Specified in Subfield $2) and the presence of subfield $2 (Source) is now reciprocal.
In Bibliographic field 082 (Dewey Decimal Classification Number), the relationship among the First Indicator (Type of Edition) and subfield $2 (Edition Information) of field 082 and the record’s Leader/06 (Type of Record) value has been corrected.
In Bibliographic fields 082 (Dewey Decimal Classification Number), 083 (Additional Dewey Decimal Classification Number), and 084 (Other Classification Number), the maximum length for a value in subfield $q (Assigning Agency) is now ten characters.
In the Validation Release Notes, November 2021, the bug fix “Improved Normalization in Duplicate Field Check” announced that the first comma would be retained for normalization only in personal name fields, whereas in all other fields, each comma would be converted to “blank” as part of normalization. Because of unsatisfactory results, OCLC is reverting this aspect of WorldCat validation to its previous state. When checking for duplicate fields in bibliographic and authority records, validation will retain the first comma in all fields rather than limiting it to personal names.
