Music cataloging using RDA involves numerous changes and challenges. The music specialist community has developed guidelines to help ensure consistent practices and quality access to music materials. This session will highlight best practices for: the use of 33X fields for scores and sound recordings; performers vs. creators and the impact on access points (especially for popular music); musical compilations; and how to determine whether, in FRBR terms, a new release of a recording or a different edition of a score is a new work, expression, or manifestation.
