Casey A. Mullin, head of Cataloging and Metadata Services at Western Washington University Libraries, recently published “An Amicable Divorce: Programmatic Derivation of Faceted Data from Library of Congress Subject Headings for Music,” in Cataloging & Classification Quarterly. The article describes efforts to adapt legacy library metadata for music resources, repurposing traditional “subject” headings as faceted descriptors, which are more granular and amenable for filtering on search results in the library catalog and other discovery environments. The faceted approach is slated to eventually replace the legacy subject heading method for music; in order to mitigate the costs of manual enhancement/conversion of legacy catalog data, automated and semi-automated processes will be required. Mullin’s article describes a sophisticated application of such processes. Limitations inherent to these processes and ideas for future directions are also described.
Casey Mullin holds a Bachelor of Music degree in viola performance from Western Washington University and a Master of Library Science degree (with music specialization) from Indiana University Bloomington.
