Details from OCLC: Library of Congress scripts

Discover details and further information about issues displaying and validating certain characters in Library of Congress records.

The Library of Congress (LC) recently announced the expansion of non-Latin script input in bibliographic and authority records. OCLC is working closely with LC to ensure that records distributed to OCLC are correctly rendered in their original scripts. OCLC will roll out support for scripts as they are validated for use and as languages continue to be implemented through Spring 2026. 

Most scripts validate and export successfully. You may experience some minor character display irregularities (e.g., dotted circles, white rectangles, spacing issues) in certain interfaces. Five characters across two scripts do not validate successfully. Please review the Known Issues section below for additional details and recommended actions.

You should export records containing these scripts in UTF-8 Unicode format in Connexion 2.63, Connexion 3.1, WorldShare Record Manager, or WorldShare Collection Manager. MARC-8 export does not support these scripts.  

We are committed to full support of LC’s script expansion and will continue to work closely with LC. Our goal is to ensure that as libraries contribute records with scripts, they integrate seamlessly across OCLC’s systems.  

Language Support and Display Optimization

Record Manager and Connexion support numerous languages for cataloging. 

For optimal display in Connexion, we recommend using either Noto Sans or Nirmala UI font. Please review the recommendations below based on your Connexion client version and working language/script. 

Other fonts may provide a similar experience in Connexion, and OCLC's font recommendation does not suggest that other fonts would not work with a given language/script. 

Recommended font for Connexion 3.1 users for all languages/scripts: Noto Sans
