This session features updates and special topics in music cataloging and metadata as well as an open discussion period; it is a forum for sharing information on important topics that do not each require their own program sessions. Speakers will provide up to date information on changes to RDA (as well as LC-PCC Policy Statements and MLA Best Practices), LCGFT, LCMPT, LCDGT, and MARC. Special topics this year include representative expressions in RDA, an update from the Cataloging Subgroup of the MLA Electronic Scores Working Group, a recap of useful music-adjacent resources, and the latest on MLA’s linked data work.
