<ul>
<li>Serial commas in all situations — alpha, beta, and gamma.</li>
<li>Quantities of twenty or fewer are spelled out as words, larger amount as digits. Exceptions are for ages, dates, and perhaps others.</li>
<li>Date format is day month year — 18 August 1957 (18 Aug 1957 in genealogies and tables).</li>
<li>Months are to be spelled out in the body of the article, but abbreviated in notes and in genealogical tables.</li>
<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>Acronyms composed of initials shall omit periods — thus USA, FAS, PhD.</li>
<li>Endnotes are preferred to footnotes. The exception is mention of prior publication, non-Society copyright, mention of prior articles in a series, and brief author bios which go in a footnote on the first page of the article marked with an asterisk.</li>
<li>If footnotes are used with a Bibliography, the footnotes shall be in brief format, “Author, Short title, vol:page” with full details in the Bibliography. Note that this approach works poorly with web sources, and is discouraged when these are used.</li>
<li>Notes are referenced by numerals within square brackets in text — [1], not superscript <sup>1</sup>.</li>
<li>Notes are listed by numerals followed by a closing square bracket — 1], not [1].</li>
<li>Do not use apostrophes in decades and centuries; thus 1920s not 1920's, and 1800s not 1800's.</li>
