Right, and I think this leads to all sorts of other ugliness, too:
FRBR-izing aggregations of things (musical albums, anthologies,
conference proceedings, etc.) is a potential UX nightmare (from both
an end user AND data entry perspective).

That said, there are enormous benefits of modeling these things, too:
I am not suggesting we sweep them under the rug (which is basically
what we've historically done), but some we're going to need to figure
out an acceptable balance.
