Thank you for posting in Microsoft Office Word Community.
I would like to know what exactly are you referring to ‘Cite the source’ in Word 2013.
In order to use ‘Wikipedia App’ in Word 2013, highlight any word in the document then click on ‘Insert’ tab > click on ‘Wikipedia’ app under ‘Apps’ section.
If ‘Wikipedia’ app is not present, then click on ‘Store’ and install ‘Wikipedia’ app.
For further queries, reply and we would be happy to assist.
Thank you.
