This document provides guidelines for properly punctuating quotations in writing. It states that periods and commas always go inside quotation marks, even for single quotes. For questions or exclamations that include quoted material, only one punctuation mark is used, placed inside the closing quotation mark. Single quotation marks are used for quotes within quotes. Quotation marks are only used for direct quotations and not for paraphrasing. Quotations longer than three lines are not enclosed in quotation marks and are formatted as a block quote instead.
