Hi Serge,
I never used an old version of EndNote, so I don’t know what groups used to be like before. However, I can tell you that in EndNote X8, you can create Group Sets that contain Groups. For example, quoting stroh above, one could have:
- Geriatric Assessment Measures
Depression
Cognition
Activities of Daily Living
“Geriatric Assessment Measures” would be the group set and “Depression”, “Cognition” and “Activities of Daily Living” would be the various groups contained within the group set.
