If you are working with someone on a particular paper or project using EndNote, you can use the export traveling library function to share only the references you used in the paper with your collaborator instead of your entire EndNote Library.
To Export a Traveling Library
1. Go to the EndNote X8 Tab in MS Word
2. Go to Tools Group and click on the Export to Endnote dropdown menu
3. Click on Export Traveling Library and name the traveling EndNote Library
4. Share the EndNote Traveling Library which consists of a xxx.enl file and a xxx.Data folder
EndNote also allows you to share your EndNote Library with other EndNote users. However, all users will have to be using EndNote X7.2 or later. All users will also need to have a EndNote Basic account, which is used to sync your EndNote Library online.
