EndNote currently has two online platforms.
After creating an account with EndNote online, sync it to your desktop library to have access to more features in your online library and all your references.
Syncing your EndNote desktop library with an online account allows you to share your library across multiple computers. It is not recommended that you use this option as a backup.
To set syncing up:
The Sync Status page will have important information including
EndNote Click (previously known as Kopernio) is a browser plugin that can assist you with saving your citations to EndNote.
It is downloaded simultaneously as EndNote desktop and requires you to register online to use it. Note: This account is separate from your EndNote Online/Web account.
EndNote Click Resources
EndNote is also available for iPad and iPhone through the App store. It allows you to view and annotate your references and PDFs on these devices and can be synced to your desktop and online library.
EndNote for iOS Resources
EndNote has recently added a Cite While You Write plugin for Google Docs. This will connect to your online account rather than your desktop library and as such, is not currently supported by the UC Library.
