How To Cite Block Quotes Chicago: The Definitive Authoritative Guide
Mastering the Chicago Manual of Style block quote format requires strict adherence to specific line breaks, indentation rules, and parenthetical or footnote placement depending on whether you use Notes and Bibliography or Author-Date style. This comprehensive guide walks you through the exact formatting architecture, structural triggers, and citation mechanics needed to ensure your manuscript meets academic publishing standards.
Foundational Formatting Standards for Chicago Style Block Quotes
Before integrating extended passages into your research paper or manuscript, you must understand the exact threshold that separates a standard inline quote from a block quote. In the Chicago Manual of Style (CMOS), any prose quotation that runs five or more lines, or poetry running three or more lines, must be formatted as a block quotation rather than enclosed in double quotation marks.
- Essential tools and resources: A reliable word processor with ruler/indentation controls, a current edition of the Chicago Manual of Style (17th or 18th edition), and your institutional style guide.
- Mandatory prerequisite knowledge: Understanding the difference between CMOS Notes and Bibliography (NB) style and Author-Date style, along with familiarity with standard hanging indents and footnote numbering.
- Execution timeline and scope: Formatting a manuscript typically takes under an hour for an average-length paper, depending on the volume of extracted source material needing adjustment.
Step-by-Step Workflow for Formatting and Citing Chicago Block Quotes
Step 1: Establish the Line Indentation and Spacing
Unlike inline quotes that remain embedded in your paragraph text, a Chicago-style block quote is set off from the surrounding text visually. You must begin a block quotation on a new line. Indent the entire block by one half-inch (0.5 inches) from the left margin, matching the standard indentation of a new paragraph.
Pro-Tip: Set a custom paragraph style in Microsoft Word or Google Docs named "Chicago Block Quote" with a 0.5-inch left indent, single spacing, and a 0.5-inch right margin if desired by your specific publisher, though standard Chicago requires only the left indent.
Step 2: Adjust Line Spacing and Quotation Marks
Single-space the entire block quotation, even if your main document text is double-spaced. Insert a blank line immediately before and after the block quote to separate it from the surrounding paragraphs. Do not enclose the block quote in quotation marks; the visual indentation itself signals to the reader that the text is quoted verbatim.
Warning: Never use italics or quotation marks around the entire block text. The only quotation marks retained inside a block quote are those that appeared inside the original source material.
Step 3: Position the Citation and Terminal Punctuation
The placement of your citation depends entirely on whether you are utilizing the Notes and Bibliography (NB) system or the Author-Date system. In the Notes and Bibliography system, a superscript footnote number typically appears at the end of the block quote, placed immediately after the final punctuation mark of the quoted text. In the Author-Date system, place the parenthetical citation (Author Year, Page) after the final punctuation mark of the block quote, followed by a period.
Pro-Tip: In the Author-Date system, unlike inline quotes where the period goes outside the closing parenthesis, the period for a block quote goes before the parenthetical citation when the citation sits on its own final line, or after the final punctuation if the citation is integrated differently.

Common Block Quote Formatting Failures and Field Fixes
- Root Cause: Double-quotation marks wrap the entire indented block.
- Actionable Fix: Remove all leading and trailing quotation marks from the block text. The visual indentation is your structural marker.
- Root Cause: The block quote is double-spaced instead of single-spaced.
- Actionable Fix: Highlight the block quotation and adjust the paragraph line spacing setting to single (1.0) while ensuring single blank lines frame the top and bottom.
- Root Cause: Incorrect placement of the footnote number or parenthetical citation relative to the final punctuation mark.
- Actionable Fix: Place the superscript footnote number directly after the final punctuation of the block text. For Author-Date, place the parenthetical reference after the final punctuation mark with a single space separating them.
- Root Cause: Indenting only the first line of the block quote rather than the entire block.
- Actionable Fix: Apply a block-level left indent of 0.5 inches to all lines within the quotation, ensuring the left margin aligns uniformly.
Frequently Asked Questions
How do I handle quote within a quote inside a Chicago block quote?
When you have quoted material inside your block quote, retain the double quotation marks that appeared in the original source. Because the outer block quote does not use quotation marks, any dialogue or nested quotes inside the source text will clearly stand out using standard double and single quotation marks.
Should block quotes be single-spaced or double-spaced in Chicago style?
Chicago style requires block quotations to be single-spaced, contrasting with the double-spaced text of the body manuscript. Always include a blank line both before and after the block quote to maintain visual separation.
Where does the period go when using an Author-Date parenthetical citation?
In the Author-Date system, the period closing the block quote appears at the end of the final sentence of the quote, followed by a space and the parenthetical citation (Author Year, Page) without an additional terminal period outside the parentheses.
What is the exact word or line count threshold for a Chicago block quote?
Any prose quote that reaches five lines or more must be formatted as a block quote. For poetry, the threshold is three lines or more. Shorter passages should remain integrated directly into your paragraph text using double quotation marks.
Do I need to use block quotes for block-formatted poetry?
Yes, poetry spanning three lines or more must be indented as a block quote, and you should preserve the original line breaks, capitalization, and internal spacing of the poem exactly as it appears in the source text.
