In Word, click in the text where the references are to be inserted.
In Endnote, mark the references you want to transfer to Word:
Endnote continuously builds a bibliography at the end of the Word document as you insert references. Unless "Instant Formatting" is set to Off.
You can change the reference style under Style.
If the style you are looking for is not listed, select "Select Another Style".
Endnote uses the program Cite While You Write (CWYW) to transfer references to Word.
If you are missing the Endnote tab in Word, follow this guide.
