There are several groups that are created automatically and are temporary; they exist only while a library is open. All of these groups may be available at the same time. Closing EndNote or just the library will delete a temporary group, but the references themselves are not deleted from the library.
The temporary groups are:
Copied References: This temporary group displays the last group of references that were retrieved in Online Search Mode and then copied into your permanent library with the References > Copy References to command or the Copy to Local Library icon on the toolbar. See How to Search an Online Database.
Duplicate References: This group shows the results of duplicate detection in your library. You can run duplicate detection with the References > Detect Duplicates command. See Finding Duplicate References.
Imported References: This group shows the last group of references imported into the library with the File > Import command. Each time you import additional references into the library, this group is replaced with the new set of references. See General Importing Instructions.
Search Results: This group shows the results of the last search performed on the current EndNote library. Each time you execute another search on the library, this group is updated with the new search results. See Simple Searches.
Find Full Text groups: When you use the References > Find Full Text > Find Full Text command to find the full text of a reference, a Find Full Text group set appears, containing several temporary groups. They include Searching, Found PDF, Found URL, and Not Found. See Finding Full Text.
Because temporary groups are deleted when you close the library, you may occasionally want to save one of them to a custom group so it is available during a later session.
To save a temporary group as a custom group:
Click on the group name to display the list of references in the group.
To select all references in the list, first click in the list, and then go to the Edit menu and choose Select All.
From the Groups menu, select Add References To > Create Group.
Name and save the new group.
Note: You are saving a specific set of references. If you add more references to your library, the search results you saved to a custom group are not updated. You would need to re-run the search to find the new references.
