If a source is cited again, only include the surname of the author, a shortened form of the title (if more than four words), and page number(s).
If you cannot ascertain the publication date of a printed work, use the abbreviation “n.d.”
No access date is required to be reported for electronic sources.
In the text, identify tables and figures separately, by number and in the order mentioned. Example: "in figure 3" rather than by location ("below").
Cite the source of the table and figure information with a “credit line” at the bottom of the table or figure and, if applicable, after the caption. The credit line should be distinguished from the caption by being enclosed in parenthesis or written in different type.
