typography. It may be selected with propriety for running titles, for the headings of tables, for subheadings, and for a clearer marking of the words and phrases that really need distinction in the text. The signature of each contributor to a magazine is usually set in italic, but it is unwisely used for side-notes, for it has many kerned or projecting letters, which are liable to break and often do break off at the endings of lines in an exposed position.
Italic may be selected occasionally to distinguish the words or clauses that serve as verbal texts for an extended comment, but it should not be selected unless there is real need for making a distinction. Small capitals are sometimes used with good effect.
In the text of a book or pamphlet, use roman for the name of the writer, but italic for the title of the cited book. In a citation that makes a full paragraph, and in all foot-notes, it is the common practice to put the name of the author as well as of the book in roman lower-case. At the end of a paragraph or foot-note, specification of author and book may be roman for author and italic for book; book alone, italic.
Select roman, without quotation-marks, for the names of papers, magazines, and serials appearing in the body of the text or in a foot-note, but when put at the end of paragraphs as credits, use italic.
When an unfamiliar foreign word is used to convey precise description, put it in italic, but use roman for repetitions of that word.
