Music-Related RDA Changes in the April RDA Toolkit Release

The April RDA Toolkit release was published on Tuesday, April 11, 2017. The release contains an RDA update, including approved proposals from the November 2016 RSC meeting. The release also contains Fast Track changes from the RSC as outlined in document RSC/Sec/7 available at the RSC website. Work continues on the synchronization of the Toolkit and Registry, part of the first phase of the larger RDA Toolkit Restructure and Redesign (3R) Project. The release also includes changes to several LC-PCC Policy Statements (LC-PCC PS), summarized in this document available at the LC website.

Several changes were also made to the MLA RDA Best Practices; these changes will be covered in a separate blog post.

To facilitate the 3R project, RDA content will be frozen until the April 2018 Toolkit release. During this time CSS will undertake a full review of the RDA Best Practices, with an eye toward synchronization with the LC-PCC PS, updating/revising examples, and looking at an alternate presentation format for Supplement 1. CSS will also continue to collect suggestions and feedback regarding the RDA best practices. Suggestions for new or revised Best Practices can be made via the submission form located in the FAQ on the CMC website.
