Sometimes you'll find that sync isn't working - Endnote might appear to Sync, but it doesn't update your online library (which you can check at myendnoteweb.com). If your sync seems to be broken, this is the procedure you should follow.
The web browser version of EndNote can be used to create bibliographies, manage references, share libraries collaboratively, and insert citations into Word via Cite While You Write. It can be used as a standalone library (though it's not a real substitute) or as a way of transferring references from desktop EndNote if you are using more than one computer.

Inserting references into Word
No software has to be installed to use EndNote Web however you will need to install a Cite While You Write toolbar if you want to insert references into a Word document or use the capture toolbar in your browser. After creating an account, signing in and viewing the 'Getting started' guide, select the "Download installers link at the bottom of the page". Please read the Endnote Web Plug-In installation instructions.
Using EndNote Web tips
Due to the variety of copyright and licensing restrictions that can apply to the redistribution of published material, it can be difficult to determine whether or not each individual attachment in an EndNote library can be shared with others. For this reason the library advices that the safest course of action for you is not to share or distribute EndNote Libraries containing attachments with someone from another institution which does not subscribe to the same databases.
You are still able to share your EndNote Libraries without attachments with collaborators outside the University (see below instructions). You may also talk to your Academic Liaison Librarian.
How to save an EndNote Library without attachments:
If you are upgrading from a previous version of EndNote, it is advisable to back up your libraries, any modified output styles, and uninstall the old version of EndNote prior to installing the new version.
