Faceted search has been widely implemented in library discovery interfaces and has provided many benefits to library users. The effectiveness of facets in library catalogs depends on a complex interaction between facet vocabularies, metadata quality and structure, and the library discovery interface’s capabilities. This article provides a holistic overview of challenges for optimally implementing facets in library catalogs. This supports a systematic approach to refining and enhancing the capacity of faceted search to improve searching and exploring bibliographic metadata.en-USCreative Commons BY-NC-ND 4.0-USfaceted searchfaceted vocabularieslibrary discovery interfaceslibrary catalogsmetadata qualityusability issuesArticle
