NOTE.—A list of foreign and anglicized words and phrases, showing which should be printed in roman and which in italic, is given on pp. 35-7.
In many works it is now common to print titles of books in italic, instead of in inverted commas. This must be determined by the directions given with the copy, but the practice must be uniform throughout the work.
Words or phrases cited from foreign languages (unless anglicized) should be in italic.
Short extracts from books, whether foreign or English, should not be in italic but in roman (between inverted commas, or otherwise, as directed on p. 63).
Names of periodicals should be in italic. Inconsistency is often caused by the prefix The being sometimes printed in italic, and sometimes roman. As a rule, print the definite article in roman, as the Standard, the Daily News. The Times is to be an exception, as that newspaper prefers to have it so. The, if it is part of the title of a book, should also be in italic letters.
Print names of ships[44] in italic. In this case, print ‘the’ in roman, as it is often uncertain whether ‘the’ is part of the title or not. For example, ‘the King George’, ‘the Revenge’; also put other prefixes in roman, as ‘H.M.S. Dreadnought’.
ad loc., cf., e.g., et seq., ib., ibid., id., i.e., loc. cit., q.v., viz.[45], not to be in italic. Print c. (= circa), ante, infra, passim, post, supra, &c.
Italic s. and d. to be generally used to express shillings and pence; and the sign £ (except in special cases) to express the pound sterling. But in catalogues and similar work the diagonal sign / or ‘shilling-mark’ is sometimes preferred to divide figures representing shillings and pence. The same sign is occasionally used in dates, as 4/2/04.
In Mathematical works, theorems are usually printed in italic.
