“ A rule or dash (—) denotes the repetition of the preceding heading, or of its first separate word. Hyphened words are treated as single words. Headings in italic type denote books, newspapers, or periodicals. Quotation marks are used for pictures, ships, statues, race horses and separate poems or musical compositions.
II. Alphabetization.—All titles, whether consisting of a single word or of more than one, and if of more, whether hyphened or not, are treated for the purpose of alphabetization as single complete headings. ”

“ The prefixes “Mc” and “M‘” are alphabetized as “Mac”; “St” is treated as “Saint,” “S.S.” as “Saints.”
III. Geographical Headings.—The names of towns and villages are followed by the abbreviation for the country to which they belong. For this purpose English counties and the states of the United States rank as countries. ”
