Interesting stuff. Thanks for sharing this. As you might know Bibliotheek.nl, the service provider for public libraries of The Netherlands, has also embarked on a FRBR mission. Software developers of OCLC Leiden have created a clustering algorithm on the bibliographic records that are included in the newly released API-based National Library Catalog (NBC). This has resulted in half a million clusters on a total of 4.7 million records. 1.2 million bibliographic records are now tied together by half a million work/expression-records. Which brings our work-instance ratio on 2.4 titels per cluster - and the number of Singletons on 3.5 million. If you want to see FRBR at work, see the NBC implementation (sorry, Dutch interface) at the public library of Amsterdam: http://zoeken.oba.nl/?hardsort=date&q=John%20le%20Carr%C3%A9&dim=dcterms:language.uri(urn:iso:std:iso:639:-2:eng)
