EndNote automatically gives each reference a unique record number (e.g. #1, #2, #3). These numbers are assigned in order and cannot be changed. If you delete a reference, its number will not be reused.

You can change which fields (such as Author, Year, Title) are shown in the Reference panel and the order they appear.

You can combine two EndNote libraries by importing one into another. Always make a backup of your main library before merging.
The references will be added to your main library and given new record numbers.

This feature checks if updated information is available for a reference. It is useful for PDFs without a DOI, records from Google Scholar or advanced publications/in-press articles.

EndNote lets you share a group of references or an entire library with other EndNote online users.
The people you invite will get an email. To see the shared group, they need to sync their library. The shared group will appear under Groups Shared by Others in the Groups panel. Clicking on it will open the group in EndNote Online.
Users can open a shared library in EndNote by going to File and Open Shared Library…
