In some situations you may want to edit a citation you’ve already added, either to correct a reference or to add more detail, such as a specific page number. To do this, begin by clicking on an existing citation. It will be highlighted in grey once you click on it.
The Insert citation button will change to read Edit Citation.
When this button is clicked the Citation Editor will open. Click on the existing reference to edit the citation and then click OK to return to your document.
If you need to remove a citation, delete it from your Word document as if it was normal text using the backspace key.
