The IMLS-funded Variations FRBR project has developed a faceted search interface, Scherzo, that works on top of 80,000 FRBRized MARC records. This talk includes a demo of Scherzo and compares the Scherzo user experience with the experience of searching for sound recordings in IUCAT. In addition, we describe and demonstrate other recent experiments in search, including Blacklight and the eXtensible Catalog
