Use consistently whatever format you and your director choose. You may use a shortened form for subsequent references to the same work, provided that enough information is given to identify it. Do not, however, use op cit. The reference number is an unpunctuated, superscribed arabic number. You may number footnotes either consecutively through each chapter, beginning a new numbering sequence with each chapter, or consecutively from beginning to end of the document.
Place footnotes at the bottom of each page.
Use the following guidelines for either programming your word processor or formatting footnotes manually. Double-space from the separation line to the first footnote. Indent the first line of each footnote. Start subsequent lines at the left margin. If you choose, you may use endnotes.
