Note: In order to prepare the student for unknown situations that may occur in the certification manuscript and future transcriptions, from this point on some topics are explained that may not be tested in the exercises.
Authors often find that they must cite sources of information to give themselves credibility and to state the sources of direct quotations, facts, and ideas other than their own. Citations can be made in several ways. The most common way is to insert a reference marker, which may be an asterisk, a dagger, a double dagger, or a superscripted number or letter in the text immediately following the material being cited. A note, preceded by the same reference marker, explaining the source of the statement is then placed at the bottom of the print page—or sometimes at the end of the chapter or even the end of the book.
