2. On the References Ribbon, in the FootnotesGroup, click either the Insert Footnote or Insert Endnote icon.
3. To adjust the settings of your footnote, including the numbering style, when to start and stop the numbering of your notes, etc., click on the Expand icon in the Footnotes Group of the References Ribbon.
   • You can have your footnotes and endnotes restart their numbering in each chapter. To do this, each chapter will need to be its own section. See Adding Page Numbers for more information on creating sections. Remember, too, that you can format the style of your endnote/footnote as discussed in the Modifying a Style section.

  Change automatic reference marks for Word endnotes
  by Mary Ann Richardson | Mar 06, 2007 8:00:00 AM
  Takeaway: If you don't like the way your Word endnote numbers look, change them! Mary Ann Richardson explains that you can change the reference marks from Roman numerals to a different format by making one simple format change.
  By default, Word uses small Roman numerals for endnote reference marks. If you decide later that you do not want to use the default number format, you don't have to delete the endnote numbers and re-create them all again. All you need to do is follow a few simple steps.
  For example, to change the Roman numerals to Arabic numbers without having to insert new ones, follow these steps:
  Click anywhere in your document.
  Go to Insert | Reference | Footnotes.
  Click Endnotes and make the appropriate selection from the Endnotes drop-down list.
  Select 1, 2 ,3... from the Number Format drop-down list.
  Select Whole Document from the Apply Changes To drop-down list.
  Click Apply.
  By clicking Apply instead of Insert, you can change all the endnotes in the document. You can also follow this procedure to change the automatic reference marks set for footnotes. The only difference is in step 3; you will click Footnotes and make the appropriate selection from the Footnotes drop-down list.
