In Scopus, to save an article you want, click the box in front of the citation then “Send to List” (you must do both: Click the box AND click “Send to List”). They will be saved in your List until you log out.
To export to RefWorks, go into your List (top bar) and choose "RIS Export" (note that you can also email citations to yourself from this bar). A file will be created and will be in your downloads folder and will probably show up in a bar along the bottom of your screen.
Import this file into RefWorks
