There are 5 different kinds of groups in EndNote Desktop: custom, smart, combination, permanent, and temporary. Permanent and temporary groups are automatically created by Desktop and you can't delete or modify them, but you can create and modify custom, smart, and combination groups. See the boxes below for instructions.
