Number the first page of your outline with a lowercase roman numeral "i". If your outline is longer than a page, number the second page "ii," the third "iii," the fourth "iv" and so on.
Position each successive numeral in the upper-right hand corner of the page. The numerals should appear flush with the right margin, and should be exactly a half-inch from the top of the page.
Make sure your last name appears before the page number. For instance, the page number headers should appear as:
Smith i
Smith ii
Smith iii
Smith iv
