Article: Set your cursor where you want the footnote or endnote number in your text. Typically this will be at the end of a sentence, but it may be after a signal phrase or author's name. Go up to the "References" tab and click "Insert Footnote" or "Insert Endnote." Word will automatically create a superscripted number in your text and move the cursor to the footnote or endnote field. You can use sequential numbers, letters, or other symbols to mark your footnotes or endnotes. You can also specify what number or letter you want them to start from. By default, footnotes or endnotes will continue sequential numbering throughout your document. If you want the numbers to restart at the beginning of each new section or chapter, you can specify this in the settings. You can enter your citation by hand, or you can use the "Insert Citation" tool to add a citation in your footnote or endnote. Choose your source from the drop-down or add a new source if you want to cite a source that you haven't entered yet.  You can also use the "Placeholder" tool if you don't yet have all the information for the source and need to add it in later. Check the formatting against your style guide to make sure it's correct before you continue. When you're ready to go back up to where you left off and start writing again, double-click the number or other symbol at the beginning of the footnote. It will send the cursor back to the end of the text. Similarly, you can double-click a superscripted footnote number in the text to check that footnote, edit, or add to it. While you can also simply scroll down the page, this is a quicker way to get there.
