Use the EndNote Cite While You Write (CWYW) Plug-in to insert references, and format citations and bibliographies automatically while you write your papers in Word.
The EndNote plug-in should be added when you install EndNote on your computer.
Note: If after installation, you do not see an EndNote Tab in Microsoft Word Ribbon or Tools Menu, Check Word Options Tab in Windows or Chooser in the Mac.
