Unique references


I have made 2 seperate lists of references from a total larger list of references. I know want to know if no references in both groups overlap, and if I have missed any references in the sorting process. 

is there a way to view the overlap between groups of references (and which references are potentially missing as compared to the total reference list)?


You can compare Groups in Endnote using Smart groups.  if you right click on a group (on a PC) “Create from Groups” – 

you can pick one and  “or” a second (in which case it will be bigger than either group, if not identical) or “not” a second (and get what is in one but not the other) or the reverse.  

The suggestion with the subgroup command doesn’t work for me. 

Did you come across anything else that effectively identifies unique references? I’d be happy to hear about it!
