[d.] Quotation marks may be used with technical terms, with slang introduced into formal writing, or with nicknames; but not with merely elevated diction, with good English that resembles slang, with nicknames that have practically become proper names, or with fictitious names from literature.

[e.] Either quotation marks or italics may be used with words to which special attention is called. (See the examples under [91e, Exception, 3].) Quotation marks are used with the titles of articles, of chapters in books, of individual short poems, and the like. Italics are used with the titles of books or of periodicals, with the names of ships, and with foreign words which are still felt to be emphatically foreign.

[f.] A quotation within a quotation should be enclosed in single quotation marks; a quotation within that, in double marks.

[g.] When a word is followed by both a quotation mark and a question mark or an exclamation point, the question mark or the exclamation point should come first if it applies to the quotation; last, if it applies to the main sentence.

[Note.]—Regarding the position of a comma, semicolon, or period at the end of a quotation, usage differs. Printers ordinarily place commas and periods inside the quotation marks, and semicolons outside, from considerations of spacing. But logic, not spacing, should determine the order, and all three marks should be treated alike. They should be placed within the quotation marks if they were a part of the original quotation; otherwise outside. In quoting manuscript, the quotation marks should enclose exactly what is in the original. In quoting oral discourse, a certain liberty is necessarily allowed.
