In order to share references, you need access to your EndNote online library. Basic users will always be online and don't need to worry about syncing anything. However, if you've got Desktop and haven't yet set up an EndNote online account, you'll need to do it now. The sync button will bring up a pop-up window that will allow you to click “Sign Up.” You can then create an online EndNote account using the email address of your choice. ” Once you've navigated to your online account, go to your groups. References can only be shared if they're in groups. ” Each group has a sharing option represented by a tiny box. Once you've clicked it, hit “manage sharing,” then “start sharing this group.” You can then enter the email address of the person you'd like to share with.  It must be the email address that someone uses to log into their EndNote online account. If your colleague doesn't have an EndNote account, you can't share your group with them!
