It is recommended that you create only one EndNote library. The Groups feature in EndNote enables you to organise your references without the need to create separate EndNote libraries.
Creating a Group Set allows you to organise groups within your EndNote library.
You can then create Groups under the Group Set
Activity: Create a group set called Security and add a group to it called Cyber security.
The same reference can be added to multiple groups. References will remain in your All References folder even if they are deleted from a group.
Activity: Add the Cyber security report reference from activity 3.2 to the Cyber security group
