FRBR is a wonderful model of our corner of reality. But users arenšt
model-oriented, they are task oriented. They are trying to get stuff done.
So the user interface has to make the translation from how systems like to
think about the world to how users think about their work. And yes, how
users think about their work is shaped by the systems and concepts theyšve
interacted with previously, setting their expectations. But not entirely.

To some extent, the Scherzo interface represents an acknowledgement of
this after what we learned in the Variations project when trying to make a
stepwise FRBRish disambiguation search interface. Herešs our paper
describing that earlier effort:
