Additional information can be added to a citation when you first insert it into your paper.
Do you need to edit your citation after adding it? Wait! Do not edit the citation text in the document, edit it in Zotero or by using the Edit Citation feature. Zotero will keep all your citations up to date for you, even if they appear in multiple places in your paper.
When you are done adding citations, click. Zotero will insert a fully-formatted and alphabetized bibliography in whatever style you have previously chosen
