General Rules for Title (required) for Entire Books Vancouver Style

Enter the title of a book as it appears in the original document, in the original language.

Capitalize only the first word of a title, proper nouns, proper adjectives, acronyms, and initialisms.

Use a colon followed by a space to separate a title from a subtitle, unless another form of punctuation (such as a question mark, period, or an exclamation point) is already present.

Follow non-English titles with a translation whenever possible; place the translation in square brackets.

End a title with a period unless a question mark or exclamation point already ends it or a Content Type or Type of Medium follows it [...], then end with a space.
