WorldCat Discovery release notes, February 2026

Display ISBD punctuation automatically in Discovery

WorldCat Discovery now applies International Standard Bibliographic Description (ISBD) punctuation to certain bibliographic fields when punctuation has been omitted from the source data. This enhancement ensures titles, publication details, and other key information are displayed with proper separators (such as colons, slashes, and semicolons), improving clarity for users.

Details
This enhancement is applied automatically in Discovery when the MARC Leader/18 position is set to "c" (indicating ISBD punctuation has been omitted). ISBD-compliant punctuation is added for display only and does not alter the underlying MARC records.
These are the bibliographic fields where ISBD punctuation is now applied:

• 245 (Title Statement)
• 250 (Edition Statement)
• 260 (Publication, Distribution, Imprint)
• 264 (Provision Statement)
• 300 (Physical Description)
• 490 (Series Statement)

ISBD punctuation rules are also applied to the corresponding 880 fields for non-Latin scripts.
Punctuation follows the ISBD standard format: space–punctuation–space. Any original punctuation added by catalogers, such as brackets or parentheses, is preserved.

Configurazione
No configuration is needed. Punctuation is automatically displayed when the MARC Leader/18 position is set to "c".

Marc 490 series fields now display in the correct cataloged order

Series information now appears in the same order it was cataloged in the record, with subfields shown in their original sequence.

Previously, records that contained multiple series fields could display in an unexpected or inconsistent order on the item details page. In some cases, two records with similar data appeared differently, which made it unclear why one series displayed correctly while another did not. 

This issue has been fixed so that series fields are displayed in the exact order they were entered in the bibliographic record, while still removing duplicate entries. As a result, series information now appears consistently and matches cataloger intent.

Transliterated titles now display on a separate line for improved readability

Titles that include both a non-Latin script and its transliterated version now display more clearly.

Previously, the transliterated text appeared immediately after the non-Latin title with no separation, making the title difficult to read. This has been fixed so the transliterated title appears on a new line and follows the same truncation rules as the main title.

DOI searches now work consistently across citation styles

DOI searches that are part of a citation now return results more reliably across a variety of citation styles.

Previously, certain citation styles failed to return results, even when they included a valid DOI. This was caused by minor formatting differences, like colons or duplicated DOIs, that led to parsing errors. The system has been updated to better extract DOIs from varied citation formats, resolving these inconsistencies.

Open Access filter now correctly excludes non-OA records when searched with the no: index

The Open Access facet now behaves consistently when combined with number (no:) index searches, ensuring that only open access items are shown when the filter is applied.

Previously, in certain edge-case workflows—such as selecting the Open Access facet after performing a keyword search and then running a no: index search without clearing filters—non-open access items could incorrectly appear with the open access icon. This happened because the system ignored the open access filter when used with direct index searches like no:.

The system now correctly respects the Open Access filter in these scenarios. When the Open Access facet is applied, only open access records will display, even when using direct index searches.
