Comparing two libraries


I have two libraries based on large searches. I want to determine whether referenes from Libarary A are in library B.

The only mention I have seen of this topic suggests using import.

Is there any other way to determine what overlap there is between two libraries?  For example, WORD has a document cmpare function. Could there be anything similar in Endnote or is the only way to identify duplicates through Import?

Any assistance is appreciated.


Not that I am aware of.  Might be worth putting it into the suggestions forum.  

Thanks - will do.
