The header consists of a shortened title in all capital letters at the left margin and the page number at the right margin; on the title page only, the shortened title is preceded by the words “Running head” and a colon. Full title, writer's name, and school halfway down the page. An author's note lists the specific information about the course or department and can provide acknowledgments and contact information. Headings, centered, help readers follow the organization. In a signal phrase, the word “and” links the names of two authors; the date is given in parentheses. Because the author is not named in the signal phrase, his name and the date appear in parentheses. When this article was first cited, all four authors were named. In subsequent citations of a work with three to five authors, “et al.” is used after the first author’s name. For a source with six or more authors, the first author’s name followed by “et al.” is used for the first and subsequent references. A quotation longer than 40 words is indented without quotation marks.
