I think we all agree that a hardback and a paperback are two different
publisher products. My impression was that one of the reasons that those
are put on the same record today was to avoid showing the user two
"copies" of the same thing when most users didn't care. We don't create
two records for c.1 and c.2 for that same reason. I think a lot is going
to depend on how easy it is to manage good user displays from our data.
(And I'm not implying that the user displays in MARC-based systems are
some high standard we should hold ourselves to.) Is a new print product
by the same publisher with the same text an instance? or a copy? What
makes for a significant difference to the user? Whatever we decide the
answer to that latter is, we need to have those distinctions in our data
so the display can make use of them.
