The volume number immediately follows the periodical title without any intervening punctuation (e.g., Ex Auditu 21). If an issue number is also given, it is added after the volume number and preceded by a comma and the abbreviation “no.” (e.g., Faith and Philosophy 25, no. 3). However, if the periodical uses only issue numbers, and not volume numbers, then the issue number is placed after the periodical title, but is preceded by a comma and the abbreviation “no.” (e.g., Image, no. 58). In all cases use arabic numerals even if the periodical uses roman numerals.
Follow the format used by the periodical—this could be a season (e.g., Spring 2007), a month (e.g., March 2007), or a specific day (e.g., March 15, 2007).
