Is there a way in Endnote X3 (or X2) to select multiple custom groups, and to see the references that belong to all the groups on the same screen?
This could be very useful and should be easy to implement, so I’m surprised that I cannot find it.
For example, I have 3 groups:
Papers not read yet
Now I would like to see in a screen all the papers that I have not read about optimisation. Groups should work more or less like “tags”, right?
