Syncing Your Library
Syncing libraries
Libraries in your desktop EndNote program, EndNote Online and your iPad EndNote can be synchronized, so that all references, attachments and notes are the same regardless of where you open the relevant library. .
Click on 'Sync Configuration' at the top left and then the button 
to start synchronising.
Or go to Library - Sync.
This window will appear:
Login with your EndNote Online account or create a new account. If you already have a Web of Science account, you can also use that account to log in to EndNote Online.
Note: Only one desktop library can be synchronised with your EndNote Online. When synchronising a new library, libraries will be merged with all original groups and references. You will be notified before this happens. If you decide to merge libaries, then use the last library as your new library.
Your login details are stored with Preferences - Sync.
