But I don't think users have *locating a copy* as their goal.  Rather, I think 
their goal is to *get their hands on the book*.

If I discover a book via COINs, and you drop me off at Worldcat.org, that 
allows me to see which libraries own the book.  But, unless I happen to be 
affiliated with those institutions, that's kinda useless information.  I have 
no real way of actually getting the book itself.

If, instead, you drop me off at your institution's link resolver menu, and 
provide me an ILL option in the event you don't have the book, the library can 
get the book for me, which is really my *goal*.

That seems like the more productive path, IMO.

Yep. That's true even for individual library's with link resolvers. OCLC is
not going to be able to solve that particular issue until the local
libraries do.

I was mainly thinking of sources that use COinS. If you have a rarely held
book, for instance, then OpenURLs resolved against random institutional
endpoints are going to mostly be unproductive. However, a "union" catalog
such as OCLC already has the information about libraries in the system that
own it. It seems like the more productive path if the goal of a user is
simply to locate a copy, where ever it is held.

Many institutions have chosen to do this. MPOW, however, represents a
counter-example and do not link out to OCLC.
