Inserting footnotes into Word documents
To insert a citation into a footnote you will need to create a footnote first by using the Insert Footnote function on the Reference tab in Word.
Find the citation and insert it the same way you do your in-text citations. A corresponding entry will be added to the bibliography.
Note: It is vital to select a footnote style when you want to insert footnotes. To view and select a footnote style, select Output Styles and then Open Style Manager from the Edit menu in EndNote. The information on each style will usually indicate if it is a footnote style. One well-known footnote style is Chicago 17th A. Many other styles will work in text and in footnotes (e.g. Harvard and APA).
