The use of footnote references in Zotero comes with some difficulties, and it is good to be aware of problems that may occur. Below, two different ways to work with footnotes in Zotero are described. They are not exclusive, but can be combined.
Inserting a footnote
In order to insert a footnote, you place the cursor at the place in the document where you want the footnote. Choose Add/Edit Citation from the Zotero tab in Word. Find the item you want by typing the author's name in the dialogue box that appears. When you press Enter, Zotero automatically inserts a footnote with the chosen item. You can also insert multiple items by writing them after one another in the dialogue box.
Note that the above only works if you are using a footnote style! Select a footnote style below Document Preferences, e.g., Chicago Manual of Style 17th edition (full note). If it is not clear from the name of the style whether it is a footnote style, try to find the style at https://editor.citationstyles.org/ > Search by name > View style; the type of style is listed below Citation format.
Writing text in the footnote
In order to add text before the item cited in a footnote, use the field Prefix. You find the field when clicking an item in the citation dialogue, which appears when you click Add/Edit Citation. Text that is supposed to follow at the item can be added in the field Suffix. Thus, all text in the footnote is written in the citation dialogue.
This way of working is best suited for short footnotes which, except for the cited items, do not contain much text. An advantage is that Zotero can automatically transform the entire footnote into an in-text parenthesis if you choose to switch from a footnote style to a parenthetical style. There are, however, a couple of issues that it might be good to know about:
Inserting a footnote
First insert a footnote manually, using the function References > Insert footnote (or short command Ctrl + Alt + F). Then place the cursor in the footnote at the bottom of the page, click Add/Edit Citation, and insert the cited item as usual.
Writing text in the footnote
You can add text in the footnote by typing it in the document outside the grey field constituting the citation. Add a new item in the same footnote, separated from the first by text, by placing the cursor where you want it and click Add/Edit Citation.
This way of working is best suited for texts with longer footnotes, containing more elaborate discussions. There are, however, some disadvantages:
