As we found when doing merging on the U Calif union catalog, you have a
trade-off -- to avoid mis-merging you will end up with more un=merged
items. The algorithms cannot overcome lack of clarity in the metadata
itself. We ended up with record sets where even a human couldn't
determine if they should be merged. I think the only solution is going
to be allowing some kind of crowd-sourcing of merge decisions as a way
to share the pain.
