 PUNCTUATION

In the following pages we have noted the preference of The Riverside Press in matters of punctuation that come up frequently. Where the punctuation of a manuscript is consistent, and when the sense of the text is not affected, the punctuation should not be changed.

Unless directions to the contrary are given, all punctuation marks should be printed in the same style or font of type as the word or letter immediately preceding them. In italics, where an abbreviation is used, with a semicolon, colon, exclamation, or interrogation point immediately following, do not use an italic mark; as, Ibid.; et seg.; where quotes follow an italic word, and the punctuation mark properly falls outside the quotes, do not use an italic mark, The Period Use after abbreviations, with the exception of chemical symbols, the format of books, the phrase per cent, and roman numerals.

Use between hours and minutes in time indications, and for decimal points: 8.30 ; 18.5.

Omit after running-heads, centred headlines, cut-in heads, and box-heads in tables.

Omit in title-page and other display matter unless especially directed to retain.

Use an en leader instead of a period in tabular composition unless the thin period is necessary to gain space.

The period is always placed inside quotation marks; and inside parentheses when the matter inclosed is an independent sentence, otherwise outside.

The Exclamation

Is used— After interjections and all words, phrases, and sentences that express great surprise, strong emotion, or forcible command.

Generally in parentheses, to express sarcasm, or contempt.

Inside the quotation marks when part of the quotation; otherwise outside.
