Many citation styles such as ACS and Chicago make use of footnotes. EndNote cannot generate footnotes, this has to be done using Word. Word will control the numbering and location of the footnotes and EndNote will control the style formatting. When using the Cite While You Write (CWYW) feature, place the cursor where you want to add the footnote. Insert a footnote using the Word menu commands. The footnote marker will appear where you placed your cursor and a footnote will appear at the bottom of the page. Place the cursor in the footnote and then select a citation from your EndNote library. EndNote will enter both the footnote citation and generate the bibliographic citation as part of the references list. Although EndNote seamlessly transitions between many citation styles, it cannot transition well from an in-text citation style such as APA 6th and a footnote style such as Chicago 16th Footnote. If you initially format your paper with APA adding in-text citations instead of footnotes when you switch over to Chicago or ACS, there will be no footnotes because you did not create them. Best practice is to select your general style (either footnote or in-text citation) before you begin CWYW.
