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.
