5.22 Reference numbers

Page numbers are usually written in Arabic numerals, but in prefatory material they may be written as lower-case Roman numerals:

• page vii of the Foreword
• page 7 of the Introduction

Within the body of the text, volume numbers may be indicated by Arabic or Roman numerals or be spelled out. Numbers of chapters and other major divisions of a book may be spelled out, but are more often written in Roman or Arabic numerals—the tendency being away from Roman numerals in the case of both chapter and volume numbers. Verse numbers and those of minor divisions of a book are written as Arabic numerals:

• I Kings 9:1–4
• Volume 18, Section 8

Paragraphs may be numbered 1, 2, . . . ; clauses within paragraphs, 1),  2), . . . . Groups of paragraphs may be numbered with Roman numerals. In citations from legislation and the like, numbers and letters designating parts of a section should be enclosed in parentheses, with no space between them:

• subparagraph 123(4)(b)(ii)
