Catalogers have been waiting since January 2020 for MARC field 532 - Accessibility Note to be included in the MARC bibliographic validation table. This MARC change was approved by LC in 2018 and has been showing up in AV records ever since. Catalogers see a "not defined" error message when saving a record which includes an unvalidated field.

Currently we may only add a local MARC tac to the validation table (eg 9XX, X9X or XX9). Otherwise, it must wait for the LC MARC bibliographic update to be implemented by Polaris development in a new Polaris version. We now hear that the 532 field was added in MARC Update Number 37 (December 2023) and is included in Polaris version 7.7, released at the end of October 2024. That's nearly 6 years since LC approval.

We'd like for LC changes to be added to the cataloging environment more quickly.
