I am constantly come across duplicating av references in online word. I have checked my library and I do not have any duplicates there. How to remove the duplications/ fix the problem?
Are the duplicates seen in your bibliography? Are you using Microsoft Word? Explain "online word". What version of Word? Have you refreshed your bibliography using the Zotero controls? You wrote, "duplicating AV references". Do you mean OF references?
Someone else here will need to help you make a determination if you have added citations from both your Zotero library and the list of sources already in your document.
