Endnote has Cite While You Write (CWYW) functionality that enables you to simultaneously add in-text citations and create bibliography entries when working in Word
CWYW commands are on an EndNote X9 or EndNote X8 tab automatically added to the Word ribbon when you download Endnote
Citations and references added using CWYW have embedded field codes linking them to their EndNote record
A key advantage of CWYW is that if you discover you have incorrectly referenced a source cited multiple times in a document, correcting it once in your library will automatically correct the citations linked to it in Word
However, CWYW's embedded field codes negate Word commands and citations or bibliography entries must be edited from the CWYW tab
