Note: This will not import the groups/ file attachments that you have in your EndNote library
Instructions
Begin by creating your RefWorks account. Consider creating a new folder in RefWorks called "EndNote import" or "EndNote library" to avoid any confusion as to what you have imported and where it has gone within RefWorks.
From within your RefWorks account, pull down the References menu and select "Import EndNote V8+ Database."
In the window that appears, click on the Browse button to locate and select your EndNote library--a file with a .enl extension on the end. You can also specify what folder you want to add your EndNote citations to within RefWorks.
Click on the Import button. RefWorks will import the citations into your EndNote library. They will appear in the "Last Imported" folder and in any folder you told RefWorks to add the citations to.
