Sharing references allow you to work effectively with your collaborators in a group project. You can share your EndNote library with your collaborators so that all parties can add, edit or remove references at the same time. To share your library, make sure all members have an EndNote Web account.
If you simply want to share with your collaborator the references inserted in a Word document, you can refer to the steps mentioned in Add References by Extracting References from Word Document.
Steps to share your online reference library:
Please note that you may wish to check if you have the right to share full-text articles with other researchers, in particular those outside PolyU. Just because EndNote doesn't prevent you from sharing content doesn't mean you have the permission to distribute articles to others.
The member you invited will receive an email and he/she needs to accept the invitation to access the shared group under Groups Shared by Others.
