<li>Calendar designation shall be either “BC” or “AD” whenever there may be ambiguity — AD 1957 or 3400 BC, but 2 January 201 AD. Articles set entirely in one era may omit these.</li>
<li>Figures, Tables, Charts, and Videos are each numbered separately (the latter only in online publications). Figures include all photographs and illustrations. Tables are defined as being columnar arranged text. Charts may combine text with graphics, such as lines indicating descent. The full words are used, not abbreviations. These terms should be followed by a number and period. Thus: "Figure 1. : Portrait of the Author." All must be called out in the text, unless circumstances dictate otherwise.</li>
<li>Credit for Figures, Tables, Charts, and Videos (where not covered by a broader Identification) are placed at the end of the caption in parentheses.</li>
