October 2025 RDA Toolkit Release

The latest release to RDA Toolkit took place on October 9 and includes changes the wording of authorized and preferred access points across all entities. There are corrections and fixes based on feedback submitted to RDA Toolkit and changes to the Guidance chapter on Aggregates. Policy statements have been added by the British Library, Library and Archives Canada, and the New Zealand National Library. This release also introduces the policy statements from the Rare Books and Materials Section (RBMS). Read the full release notes. It is also worth mentioning that the Spanish translation of Offical RDA debuted last week.

This release is the final one under our new publishing calendar. Next year, the release schedule will follow the same pattern, with releases in February, June, and October. In each release the English-language version is published first, and the translations will follow in the weeks after. 

Updates on the progress of this release will be posted here. The full release will be completed before the end of the month.
