The Complete Guide to Chicago Style

Allison Bressmer

The Chicago Manual of Style (CMOS) is a widely used style guide that covers topics like preparing manuscripts for publication, grammar rules, and word usage. It also offers two style options for source citation .

While Chicago Style is more often used for published works than high school or undergraduate class papers, Kate Turabian developed a simplified version of the CMOS’s citation styles, with modifications that address the needs of student writers.

What Does the Chicago Manual of Style Do?

Chicago manual of style general formatting guidelines, how to format an in-text chicago-style citation, guidelines for formatting reference and bibliography pages, why are citations and references necessary.

The purpose of CMOS, or any style guide, is to create a system of standardization across a publication, company, publishing house, or project, etc.

Language and conventions of language, grammar, and word usage are fluid and influenced by social location or other factors, so style manuals provide rules or guidelines to establish consistency.

Additionally, style guides provide easy navigation for readers by creating a clear framework for how sources are cited, documented, and located, should the reader want to investigate that source further.

The CMOS offers these general guidelines for formatting papers:

• Margins should be no less than 1 inch and no more than 1.5 inches around the paper; margins should be consistent throughout.
• The body of the main text should be double spaced .
• Block quotations, notes, bibliography entries, table titles, and figure captions are single spaced .
• Text should be left-justified .
• New paragraphs should be indented by one half inch.
• Font size and style should be legible . While CMOS does not offer a specific font preference, the Turabian guide recommends Times New Roman (12 point) or Calibri (11 point) for student papers.
• Each page of the document should have a header in the top-right corner that includes the page number .

What About a Title Page?

CMOS does not require a title page. However, if the publication you’re writing for requires one, you’ll need to follow their format.

The Turabian guide states that class papers may require either a title on the first page of text or a title page. If you need to include a title page, the recommendations are as follows:

• Center the title one-third of the way down the page.
• The subtitle , if you have one, goes under the title . Put a colon after the title if you have a subtitle.
• Your name , class information , and the date should be included a few lines (3-4 return hits) later, each a separate line.
• All information should be double-spaced .

What About Headings?

In CMOS, consistency is key. There is no set rule for headings and subheadings, other than that they should be consistent throughout the work. Think of them as visual cues.

A reader should be able to recognize that “this font at that size” is a chapter beginning. Or “that font in this size” signals a main subsection of a chapter, and so on.

Other CMOS Style Elements to Know

Because there is variety even within the CMOS, it’s important to remember to check with your instructor or publisher about the specific style methods they follow and to ensure you understand any preferences not specifically stated in the CMOS guidelines.

Here are some common sticking points you may have questions about.

Introduce acronyms the first time you refer to the entity or concept, etc., that they stand for. The first line of this article demonstrates that practice.

The Chicago Manual of Style (CMOS) is a widely used style guide . . . .

ProWritingAid's Acronym Report checks this for you, highlighting any un-introduced acronyms in your text, as well as any inconsistent acronyms:

Use words rather than numerals for numbers under 100. For example, write out twenty-eight instead of 28. There are exceptions to this rule: Use numerals when referring to a specific measurement; for example, 1 inch, and when using decimals. Also, for more technical writing, CMOS advocates spelling out numbers one through nine, but using numerals for any figure with two or more digits.

“Block” a prose quotation of five or more lines. This means the entire quote should be indented, or set off, from the surrounding text. Do not use quotation marks around blocked quotations. Use the same font style and size for the blocked quote as you used for the surrounding text.

Use “headline-style” capitalization for titles mentioned in the text, notes, or bibliography. Headline style means the first words of titles and subtitles, as well as any principal words that follow, are capitalized. Principal words include the first and last words of the title, as well as any words that are not conjunctions, articles, or prepositions. Use italics or quotation marks for titles depending on the works they represent.

Figures and Tables

If you include a figure or table in your work, follow these elements of CMOS:

• Position the figure under the information that discusses that figure.
• Put the caption directly under the image or figure and flush with the left edge of the figure. Use single spacing for the caption.
• Leave at least one blank line between the caption and the continuing text in your document.
• Label the image and ensure that labels are consecutive. For example, Figure 1; Figure 2; Figure 2.1.

CMOS offers two options for in-text citations and their respective reference or bibliography pages: author-date and notes and bibliography .

The Author-Date System

The author-date style is used more commonly in physical and social sciences. With this method, sources are cited in the text, usually with a parenthetical citation that includes the author’s last name and the year the cited work was published.

To find full bibliographic information on the source, the reader can consult the reference list and find the corresponding entry.

This method offers the writer some flexibility in how to integrate citations into their texts.

Examples of Author-Date Style

Let's pretend I ran an experiment on the most popular color of M&Ms among five-year-olds. I conducted the study in 2020 (because what else was there to do during a pandemic?), and you want to include my findings in your paper.

With the author-date format, you could use either of these possibilities:

The study revealed that five-year-olds prefer blue and green M&Ms to brown and yellow ones (Bressmer 2020).

Bressmer (2020) determined that five-year-olds prefer blue and green M&Ms to brown and yellow ones.

If I had worked with one or two others—say, Johnson and Smith—on my study, you would simply add their names to the citation, like this:

• The study revealed that five-year-olds prefer blue and green M&Ms to brown and yellow ones (Bressmer, Johnson, and Smith 2020).

If any additional researchers were involved in the study (making the total four or more names), you would use (Bressmer et al. 2020).

If you need to cite more than one reference in a single in-text citation, use semicolons to separate those references.

• One study revealed that five-year-olds prefer blue and green M&Ms to brown and yellow ones, but a subsequent study indicates that blue is preferred even over green (Bressmer 2020; Phillips 2021).

If I had conducted both of those studies (not Phillips), only a comma would be required between the dates: (Bressmer 2020, 2021).

Author-Date Reference List

If you use the author-date style, you must include a list of references as the last page of your work. Each of your in-text citations must have a corresponding entry on the reference list that includes the full bibliographic information for the source.

The reference list should only include sources you’ve cited in the document.

The Notes and Bibliography System

This system is often preferred by those working in the humanities. It has flexibility and provides an opportunity for commenting on sources, if the writer feels a comment is necessary.

In the notes and bibliography style, writers acknowledge they have used a source by putting a superscript number at the end of the sentence in which that source is referenced. If the reference is a direct quote, then the superscript should immediately follow the quotation. The note number should also follow punctuation, rather than precede it.

Footnotes and Endnotes

Using either footnotes or endnotes , the writer includes a numbered note that corresponds to the in-text superscript number either at the bottom of the page on which the reference is used, in which case the note is called a footnote , or in a compiled list of notes at the end of a chapter, or the entire document, called endnotes .

Footnotes and endnotes include bibliographic information for the cited source. These notes then correspond to entries on the last page of the paper, the bibliography.

Usually, the first time a source is listed as a footnote or endnote , it is appropriate to use a full note, which includes full publication details of the source.

If a source is included in subsequent footnotes or endnotes , it’s common practice to use short notes , which include the author’s last name, title of the work, and page number, if relevant. However, always check with your instructor or publisher and follow their recommendations.

Example of Notes and Bibliography Style

Imagine the sentence below appears in the text of a document in which the writer referenced my M&M study. Note the superscript after the referenced material and the corresponding footnote (full-note form) at the “bottom” of my page. A thin line separates footnotes from the main text, and the footnotes appear in a font of the same or smaller size than the main text.

The study revealed that five-year-olds prefer blue and green M&Ms to brown and yellow ones.1

A short-note version would simply include

• Bressmer, “The M&M Attraction Study,” 5.

The Notes-Bibliography Style Bibliography Page

While a reference list is required for papers written with the author-date system, a bibliography is not required for works written with the notes-and-bibliography system, though they are generally preferred. Once again, check with your instructor or publisher.

The bibliography includes sources cited in your paper and may list other sources you referenced in preparing the work but did not specifically cite.

For the most part, format the reference and bibliography pages the same way.

Either list starts on a new, blank page that comes at the end of your document.

• Title the document as References or Bibliography , depending on the CMOS citation system used in the document. Center that title word, but do not underline or put it in quotation marks.
• Leave two blank lines between the title and your first entry.
• Single space the lines of each entry; if the entry has more than one line, use a hanging indent for all subsequent lines (this just means the lines are indented, or “tabbed”).
• Leave one blank line between entries.
• Alphabetize entries by author’s name; if no author, then by the first word of the entry (probably the title of the article/work).

What to Include in Chicago-Style Reference and Bibliography Entries

Other than their titles, the only other difference between the reference and bibliography pages is regarding the placement of the publication date. On a reference list, place the year of publication immediately after the author’s name.

Major Elements

Include the following major elements in reference and bibliography entries and separate the elements with periods:

• Author’s name: last name first, with a comma separating the names. For example, Johnson, Joan.

Reminder: on a reference list , the publication date appears directly after the author’s name.

Title: Italicize titles of books and journals. Use quotation marks for titles of articles, chapters, short stories, or poems.

Publication information: Name of journal (or larger work in which the cited article, chapter, etc., appears), publisher, year of publication.

If additional information about the source is available:

• After the title, include others involved in producing the work (editors, translators, compilers); edition number if the work is not the first edition; volume or series numbers.
• After publication information, include page numbers; URLs, or DOIs (digital object identifiers) of sources accessed through electronic databases.

By acknowledging the author of a source cited in your paper, you do the following:

• Uphold standards of intellectual and academic honesty by acknowledging the authors of the information you’ve borrowed for your paper. It’s never okay to try to pass off someone else’s work or ideas as your own—that is called plagiarism.

For more help ensuring your work is presented honestly, sign up for ProWritingAid’s Plagiarism Checks —and rest assured your work will not be stored or sold.

Establish credibility by including the voices and works of others as support for your ideas, arguments, or proposals. When you do this, you validate the credibility of your ideas.

Help your readers by leading them to the source of each of your citations. Should they want to investigate further, your citations will lead to your reference page, which provides the location of your source.

The Chicago Manual of Style offers versatility for writers, allowing them to adapt their citations to the style that suits their work (or their instructor’s or publisher’s request), while ensuring readers can easily identify and locate those cited sources for further investigation.

This section contains information on The Chicago Manual of Style  (CMOS) method of document formatting and citation. These resources follow the seventeenth edition of The Chicago Manual of Style (17t h e dition), which was issued in 2017.

Please note that although these resources reflect the most recent updates in the The Chicago Manual of Style  (17 th  edition) concerning documentation practices, you can review a full list of updates concerning usage, technology, professional practice, etc. at  The Chicago Manual of Style Online .

Introduction

The Chicago Manual of Style  (CMOS) covers a variety of topics from manuscript preparation and publication to grammar, usage, and documentation, and as such, it has been lovingly dubbed the “editor's bible.”

The material on this page focuses primarily on one of the two CMOS documentation styles: the Notes-Bibliography System (NB) , which is used by those working in literature, history, and the arts. The other documentation style, the Author-Date System, is nearly identical in content but slightly different in form and is preferred by those working in the social sciences.

Though the two systems both convey all of the important information about each source, they differ not only in terms of the way they direct readers to these sources, but also in terms of their formatting (e.g., the position of dates in citation entries). For examples of how these citation styles work in research papers, consult our sample papers: 

Author-Date Sample Paper

NB Sample Paper

In addition to consulting  The Chicago Manual of Style  (17th edition) for more information, students may also find it useful to consult Kate L. Turabian's  Manual for Writers of Research Papers, Theses, and Dissertations  (8th edition). This manual, which presents what is commonly known as the "Turabian" citation style, follows the two CMOS patterns of documentation but offers slight modifications suited to student texts.

Notes and Bibliography (NB) in Chicago style

The Chicago Notes and Bibliography (NB) system is often used in the humanities to provide writers with a system for referencing their sources through the use of footnotes, endnotes, and through the use of a bibliography. This offers writers a flexible option for citation and provides   an outlet for commenting on those sources, if needed. Proper use of the Notes and Bibliography system builds a writer’s credibility by demonstrating their accountability to source material. In addition, it can protect writers from accusations of plagiarism, which is the intentional or accidental uncredited use of source material created by others.

Introduction to Notes

In the Notes and Bibliography system, you should include a note (endnote or footnote) each time you use a source, whether through a direct quote, paraphrase, or summary. Footnotes are added at the end of the page on which the source is referenced, while endnotes are compiled at the end of each chapter or at the end of the entire document.

In either case, a superscript number corresponding to a note, along with the bibliographic information for that source, should be placed in the text following the end of the sentence or clause in which the source is referenced.

If a work includes a bibliography, which is typically preferred, then it is not necessary to provide full publication details in notes. However, if a bibliography is not included with a work, the first note for each source should include  all  relevant information about the source: author’s full name, source title, and facts of publication. If you cite the same source again, or if a bibliography is included in the work, the note only needs to include the surname of the author, a shortened form of the title (if more than four words), and the page number(s). However, in a work that does not include a bibliography, it is recommended that the full citation be repeated when it is first used in a new chapter.

In contrast to earlier editions of CMOS, if you cite the same source two or more times consecutively, CMOS recommends using shortened citations. In a work with a bibliography, the first reference should use a shortened citation which includes the author’s name, the source title, and the page number(s), and consecutive references to the same work may omit the source title and simply include the author and page number. Although discouraged by CMOS, if you cite the same source and page number(s) from a single source two or more times consecutively, it is also possible to utilize the word “Ibid.,” ( from the Latin ibidem, which means “in the same place,”) as the corresponding note. If you use the same source but a draw from different new page, the corresponding note should use “Ibid.” followed by a comma and the new page number(s).

In the NB system, the footnote or endnote itself begins with the appropriate full-sized number, followed by a period and then a space.

Introduction to Bibliographies

In the NB system, the bibliography provides an alphabetical list of all sources used in a given work. This page, most often titled Bibliography, is usually placed at the end of the work preceding the index. It should include all sources cited within the work and may sometimes include other relevant sources that were not cited but provide further reading.

Although bibliographic entries for various sources may be formatted differently, all included sources (books, articles, websites, etc.) are arranged alphabetically by author’s last name. If no author or editor is listed, the title or, as a last resort, a descriptive phrase may be used.

Though useful, a bibliography is not required in works that provide full bibliographic information in the notes.

Common Elements

All entries in the bibliography will include the author (or editor, compiler, translator), title, and publication information.

Author Names

The author’s name is inverted in the bibliography, placing the last name first and separating the last name and first name with a comma; for example, John Smith becomes Smith, John.

Titles of books and journals are italicized. Titles of articles, chapters, poems, etc. are placed in quotation marks .

Publication Information

The year of publication is listed after the publisher or journal name .

Punctuation

In a bibliography, all major elements are separated by periods.

For more information and specific examples, see the sections on  Books  and  Periodicals .

Please note that this OWL resource provides basic information regarding the formatting of entries used in the bibliography.

How to Write and Format a Chicago Style Paper [With Examples]

3-minute read

• 18th August 2023

Are you working on a Chicago style project but struggling with the question, “just what is it?!”

Fear not, this post will walk you through Chicago style basics.

What Is Chicago Style?

The Chicago Manual of Style (CMoS) is a comprehensive style guide primarily used by professional writers, publishers, and researchers. It covers various forms of writing, including books, journals, magazines, and other publications. It’s often the go-to style for publishers and editors. CMoS is also known for its emphasis on scholarly writing and is suitable for a wide range of disciplines, including history, literature, the arts, and social sciences.

However, there’s an important distinction between Chicago style and Turabian style , which is essentially a simplified version of CMoS used in scholarly writing. Turabian omits some of the complexities and focuses on the needs of academic writers, especially those in the humanities and social sciences.

With either style, it’s essential to consult the relevant edition of the style guide specified by your institution or publication: either The Chicago Manual of Style or A Manual for Writers by Kate L. Turabian (currently in its ninth edition).

How Are Chicago Style Citations Formatted?

CMoS emphasizes two primary documentation systems : the notes and bibliography system (often used in the humanities) and the author–date system (preferred in the sciences and social sciences). When formatting a CMoS/Turabian paper, you’ll need to adhere to the guidelines associated with your chosen documentation system.

Notes and Bibliography System:

●  In this system, you’ll use footnotes or endnotes to cite sources within the text.

●  A corresponding bibliography is included at the end of the paper, listing all sources in alphabetical order.

●  Citations typically include author names, titles, publication details, and page numbers.

Author–Date System:

●  In the author–date system, you’ll incorporate in-text citations within parentheses.

●  A reference list is included at the end of the document, providing full details for each cited source.

●  Citations include author’s last names, publication year, and page numbers (if applicable).

What Does Turabian Style Formatting Look Like?

A well-structured Turabian Style paper should adhere to the following formatting guidelines :

•   Title page : Include the title of your paper, your name, the course name/number, instructor’s name, and the date on a separate page, starting a third of the page down. Alternatively, write the title on the first page.
•   Margins : Apply one-inch margins on all sides.
• Indentation and spacing : Indent paragraphs and double-space the main text.
• Font : Use a legible 12-point font (e.g., Times New Roman).
• Page numbers : Number all pages consecutively in the top right corner, starting with the first page. Alternatively, page numbers may be placed at the bottom center of the page.
• Headings and subheadings : Use headline-style capitalization for headings and subheadings, with different levels distinguished.
• Footnotes or in-text citations: Implement your chosen citation system consistently throughout the paper.
• Bibliography or reference list : Include a comprehensive list of all sources used, following Chicago style citation guidelines for your chosen system.

How Should I Choose Which Chicago Style Documentation to Use?

It’s crucial to find out which specific CMoS system is preferred by your institution, publisher, or field of study. Always consult your assignment guidelines or style manual to determine whether you should use the notes and bibliography system or the author–date system. This choice will significantly impact how you format your citations and references.

Remember that mastering CMoS takes practice. By following these guidelines, you’ll be well on your way to crafting polished, professionally formatted papers that meet the expectations of your academic or professional audience.

Chicago Style Format: A Step-by-Step Manual

The Chicago Manual of Style, a literary authority that has significantly shaped the world of writing and publishing, boasts a legacy that spans well over a century. Since its establishment in 1906, this venerable style guide has played a pivotal role in maintaining the highest standards of writing and publishing across various disciplines. Its enduring influence is nothing short of remarkable, leaving an indelible mark on the realms of academia, journalism, and professional publishing.

Chicago Style Format: Short Description

In this article, our experts, who handle your ' write my paper ' requests, will embark on a journey through the corridors of this iconic guide, delving into its rich history, indispensable guidelines, and the profound impact it continues to exert on the world of written communication. Whether you're a student striving for academic excellence, a seasoned writer crafting prose, or an editor refining manuscripts, the Chicago Manual of Style remains an indispensable companion in your quest for precision and eloquence in language and presentation.

What Is the Chicago Manual of Style

The Chicago Manual of Style, often affectionately referred to as 'Chicago,' stands as a formidable pillar of authority in the realm of writing and publishing. First published in 1906 by the University of Chicago Press, this venerable guide is much more than a rulebook; it is an enduring testament to the meticulous artistry of language and presentation.

At its core, the Chicago Manual of Style serves as a comprehensive reference for writers, editors, and publishers, offering guidance on everything from grammar and punctuation to citation styles and manuscript formatting. Its authority extends across an array of disciplines, making it a trusted companion for academics, journalists, historians, and authors alike.

The difference between MLA and APA and Chicago Styles :

While the goal of all major style guides is to ensure clarity, consistency, and credibility in writing, each has its own unique approach.

Chicago is renowned for its flexibility, making it a preferred choice for disciplines like history and the humanities. It utilizes both footnotes or endnotes and a bibliography to cite sources, allowing for detailed referencing and extensive historical context.

In contrast, the Modern Language Association (MLA) style is commonly adopted in the fields of literature, arts, and humanities. MLA is known for its straightforward, in-text citation style and Works Cited page.

The American Psychological Association (APA) style, favored in the social sciences, psychology, and education, employs a concise in-text citation system and a references page, which highlights the publication date and emphasizes the currency of research.

Distinguishing Chicago from Turabian Style

Is Chicago the same as Turabian? It's a question that often leaves students scratching their heads in confusion. Chicago and Turabian are like two branches of the same family tree, both descended from the hallowed halls of the University of Chicago.

Chicago Style format comes in two flavors: notes and bibliography, often favored in humanities, and the author-date system, more prevalent in the sciences. Turabian, created as a student-friendly adaptation of Chicago, primarily employs the notes and bibliography system. Thus, if you're a student or navigating the social sciences and humanities, Turabian might be your go-to choice.

Another key difference lies in the level of detail. Chicago is comprehensive, bordering on exhaustive, making it ideal for complex research projects. Turabian, in contrast, provides clear and concise guidelines suitable for most academic endeavors. While Chicago exudes a sense of scholarly tradition, Turabian is seen as more practical and approachable. Ultimately, your choice between these two styles depends on your academic journey and the expectations of your scholarly audience, akin to selecting the right wine from the same vineyard with distinct flavors.

Basic Guidelines

Chicago Style citation, renowned for its versatility and rigorous standards, provides a structured framework for scholars to create their intellectual canvases. Our expert service, where you have the option to buy essay , delves into the fundamental principles that underpin this renowned style, ensuring your academic work shines with precision and clarity.

Chicago Style Cover Page

The title page, often considered the gateway to your scholarly journey, holds the key to making a striking first impression. While specifics may vary per your instructor's preferences, here are the foundational principles to craft a compelling Chicago cover page:

• Title Placement: The title of Chicago-style papers should take center stage, situated one-third of the way down from the top of the page.
• Comprehensive Information: Following the title, provide essential details such as the author's name, class information, and the date, each on separate lines and all generously double-spaced.
• Subtitle Synergy: Should your work demand a subtitle, elegantly incorporate it by ending the title line with a colon, followed by the subtitle on the subsequent line.

Understanding the difference between Chicago and Turabian styles is crucial. In Chicago Style, having a title page is typically the norm. However, Turabian provides more flexibility, similar to the choice you have when learning how to write an essay introduction in Turabian.

In Turabian, you can either opt for a title page or simply start your document with the title on the first page before your main content. If your professor requests a title page in Turabian, apply the same rules discussed earlier. Keep in mind that whether you're following Chicago or Turabian, your title page plays a role akin to an introduction in your academic work. Hence, it's essential to format it correctly and adhere to the guidelines.

Whether you're writing a synthesis essay or any other Chicago-style paper, the main body is where scholarly communication and rigorous research intersect, requiring clarity, precision, and adherence to citation standards.

• Structured Organization: Divide content into sections or headings for clarity.
• Citational Rigor: Follow strict citation rules, aligning with Chicago's guidelines.
• Clarity and Precision: Emphasize clear language, grammar, and syntax.
• Evidence Integration: Seamlessly incorporate evidence and data into the narrative.
• Depth of Analysis: Encourage in-depth exploration and critical engagement.
• Scholarly Voice: Balance academic rigor with accessible language.
• Interdisciplinary Flexibility: Adapt to various academic disciplines effectively.

Headings in the Chicago Manual of Style play a pivotal role in guiding readers through the complexities of academic writing. 

Here's a succinct overview:

1. Hierarchy Matters: Chicago Style recognizes several levels of headings, each serving a distinct purpose. These include:

• Level 1: Centered, bold or italicized, headline-style capitalization.
• Level 2: Centered, regular font, headline-style capitalization.
• Level 3: Flush left, bold or italicized, headline-style capitalization.
• Level 4: Flush left, regular font, headline-style capitalization.

2. Clarity Is Key: Headings should be clear and informative. They should give the reader a sense of the section's content without the need to delve into the details.

3. Consistency Rules: Maintain a consistent hierarchy throughout your work. If you start with a Level 1 heading, continue in the same fashion for subsequent sections. Consistency enhances readability.

4. Avoid Overuse: Don't clutter your text with too many headings. Use them judiciously to highlight major sections or key points within those sections.

5. Capitalization Rules: Pay close attention to capitalization style within headings. In headline-style capitalization, major words are capitalized, while minor words are in lowercase unless they are the first or last words in the heading.

In-Text Citations and Notes

In Chicago Style format, the judicious use of in-text citations and notes is a hallmark of academic rigor. Here's a helpful guide on how to employ them effectively, even when learning how to write a nursing essay :

1. Notes and Bibliography vs. Author-Date: Chicago Style offers two primary citation systems—Notes and Bibliography (used predominantly in the humanities) and the Author-Date system (commonly employed in the sciences). Ensure you understand which system is appropriate for your field of study.

2. Notes and Bibliography System: If using this system, employ footnotes or endnotes to cite sources. Place a superscript numeral (1, 2, 3, etc.) in the text where the citation is needed. The corresponding citation details appear at the bottom of the page (footnotes) or at the end of the document (endnotes).

3. Author-Date System: In this system, the author's last name and the publication year are placed in parentheses within the text, e.g., (Gerber, 2022). The full citation details are listed in the reference list at the end of the document.

4. Abbreviations: Familiarize yourself with common abbreviations used in Chicago Style, such as 'ibid.' for 'the same source' and 'et al.' for 'and others.' These abbreviations aid in concise and consistent note and citation formatting.

5. Bibliography or Reference List: Conclude your document with a comprehensive bibliography (Notes and Bibliography system) or a reference list (Author-Date system). Ensure that all sources cited in your text are included in this section, and follow Chicago Style guidelines for formatting.

Block Quotes

Block quotes, a distinctive feature of the Chicago Manual of Style, serve as a powerful tool for amplifying the wisdom of experts and honoring the sources that enrich your academic work. Here's a succinct guide on how to effectively employ block quotes:

• Block Quote Length: Use block quotes for substantial text excerpts, usually 100 words or more in Notes and Bibliography or 50 words or more in Author-Date.
• Block Quote Format: Chicago Style indents block quotes 0.5 inches from the left margin. No quotation marks are needed, just a single space before and after.
• Cite in Block Quotes: Always include proper citations in block quotes, either within the quote or immediately following it, with author, date, and page number.
• Consistent Usage: If using block quotes, apply them consistently throughout your document, following Chicago Style guidelines.
• Integrate with Context: Seamlessly integrate block quotes into your text, providing context before and after. Explain their relevance to your argument.
• Citation Style Consistency: Ensure block quote citations match the chosen Chicago Style system (Notes and Bibliography or Author-Date) and place citations correctly.
• Shortening Block Quotes: Use ellipses (...) to shorten block quotes when necessary, ensuring the original meaning is preserved.
• Adding Clarity: If you insert your own words within a block quote for clarity, enclose them in square brackets ([...]) to differentiate them from the original text.
• Punctuation Placement: Final punctuation (period, question mark, exclamation point) goes inside the quotation mark unless it's part of the original quote.

Numbers and Acronyms

In Chicago Style Format, it's generally advisable to express numbers below 100 in words rather than numerals. Therefore, it's preferable to write 'seventy-five' instead of '75.' However, when referring to specific measurements, such as '15 pounds,' you should still use numerals.

Regarding acronyms, it's essential to provide an explanation the first time you introduce them, along with their full expansion in parentheses.

Example: The House Price Index (HPI) reveals...

Subsequently, you can use the acronym alone. Avoid starting sentences with numerals or acronyms. You should either rephrase the sentence to place the numeral or acronym elsewhere or spell out the complete phrase or number. Instead of '200 people answered the question' or 'Two hundred people answered the question,' use 'We received 200 responses.'

Chicago Style Bibliography: Footnotes and Endnotes

In Chicago Style, the use of footnotes and endnotes is a distinctive feature of the Notes and Bibliography system. These notes serve a dual purpose: providing additional information or explanations while also citing sources.

Footnotes appear at the bottom of the page where a reference or explanation is needed. They are marked with superscript numbers in the text, corresponding to the note at the bottom of the page .

• Placement: Place footnotes at the bottom of the page where the reference or explanation is needed.
• Superscript Numbers: In the text, mark the location for a footnote with a superscript numeral, usually placed after punctuation marks.
• Content: Footnotes can include additional information, explanations, or citations. Provide enough detail to support your argument or provide context.
• Citations: When citing a source in a footnote, use the full citation format, including author, title, publication details, and page number. Follow Chicago Style citation guidelines.

Endnotes in Chicago style, on the other hand, are placed at the end of the document, often before the bibliography section. They follow the same numbering system as footnotes but are collected in one place.

• Placement: Place endnotes at the end of the document, often just before the bibliography section.
• Numerical Continuity: Use the same numbering system as footnotes throughout the document for consistency.
• Content: Similar to footnotes, endnotes can contain additional information, explanations, or citations. They serve the same purposes as footnotes but are collected in one location.
• Citations: When citing a source in an endnote, use the full citation format, following Chicago Style guidelines.

You’re opening your laptop to write an essay, knowing exactly what you want to write, but then it hits you—you don’t know how to format it! Using the correct format when writing an essay can help your paper look polished and professional while earning you full credit. There are 3 common essay formats—MLA, APA, and Chicago Style—and we’ll teach you the basics of properly formatting each in this article. So, before you shut your laptop in frustration, take a deep breath and keep reading because soon you’ll be formatting like a pro.

Setting Up Your Document

• If you can’t find information on the style guide you should be following, talk to your instructor after class to discuss the assignment or send them a quick email with your questions.
• If your instructor lets you pick the format of your essay, opt for the style that matches your course or degree best: MLA is best for English and humanities; APA is typically for education, psychology, and sciences; Chicago Style is common for business, history, and fine arts.

• Most word processors default to 1 inch (2.5 cm) margins.

• Do not change the font size, style, or color throughout your essay.

• Change the spacing on Google Docs by clicking on Format , and then selecting “Line spacing.”
• Click on Layout in Microsoft Word, and then click the arrow at the bottom left of the “paragraph” section.

• Using the page number function will create consecutive numbering.
• When using Chicago Style, don’t include a page number on your title page. The first page after the title page should be numbered starting at 2. [4] X Research source
• In APA format, a running heading may be required in the left-hand header. This is a maximum of 50 characters that’s the full or abbreviated version of your essay’s title. [5] X Research source

• For APA formatting, place the title in bold at the center of the page 3 to 4 lines down from the top. Insert one double-spaced line under the title and type your name. Under your name, in separate centered lines, type out the name of your school, course, instructor, and assignment due date. [6] X Research source
• For Chicago Style, set your cursor ⅓ of the way down the page, then type your title. In the very center of your page, put your name. Move your cursor ⅔ down the page, then write your course number, followed by your instructor’s name and paper due date on separate, double-spaced lines. [7] X Trustworthy Source Purdue Online Writing Lab Trusted resource for writing and citation guidelines Go to source

• Double-space the heading like the rest of your paper.

Writing the Essay Body

• Use standard capitalization rules for your title.
• Do not underline, italicize, or put quotation marks around your title, unless you include other titles of referred texts.

• A good hook might include a quote, statistic, or rhetorical question.
• For example, you might write, “Every day in the United States, accidents caused by distracted drivers kill 9 people and injure more than 1,000 others.”

• "Action must be taken to reduce accidents caused by distracted driving, including enacting laws against texting while driving, educating the public about the risks, and giving strong punishments to offenders."
• "Although passing and enforcing new laws can be challenging, the best way to reduce accidents caused by distracted driving is to enact a law against texting, educate the public about the new law, and levy strong penalties."

• Use transitions between paragraphs so your paper flows well. For example, say, “In addition to,” “Similarly,” or “On the other hand.” [12] X Research source

• A statement of impact might be, "Every day that distracted driving goes unaddressed, another 9 families must plan a funeral."
• A call to action might read, “Fewer distracted driving accidents are possible, but only if every driver keeps their focus on the road.”

Using References

• In MLA format, citations should include the author’s last name and the page number where you found the information. If the author's name appears in the sentence, use just the page number. [14] X Trustworthy Source Purdue Online Writing Lab Trusted resource for writing and citation guidelines Go to source
• For APA format, include the author’s last name and the publication year. If the author’s name appears in the sentence, use just the year. [15] X Trustworthy Source Purdue Online Writing Lab Trusted resource for writing and citation guidelines Go to source
• If you don’t use parenthetical or internal citations, your instructor may accuse you of plagiarizing.

• At the bottom of the page, include the source’s information from your bibliography page next to the footnote number. [16] X Trustworthy Source Purdue Online Writing Lab Trusted resource for writing and citation guidelines Go to source
• Each footnote should be numbered consecutively.

• If you’re using MLA format , this page will be titled “Works Cited.”
• In APA and Chicago Style, title the page “References.”

• If you have more than one work from the same author, list alphabetically following the title name for MLA and by earliest to latest publication year for APA and Chicago Style.
• Double-space the references page like the rest of your paper.
• Use a hanging indent of 0.5 inches (1.3 cm) if your citations are longer than one line. Press Tab to indent any lines after the first. [17] X Research source
• Citations should include (when applicable) the author(s)’s name(s), title of the work, publication date and/or year, and page numbers.
• Sites like Grammarly , EasyBib , and MyBib can help generate citations if you get stuck.

An example of an MLA annotated bibliography. From the Purdue OWL.

Assemble your paper in the following order:

• Body of paper
• Appendix (if needed)
• Bibliography

Use Times New Roman, Size 12 (unless otherwise instructed).

Margins and Indents

Your margins should be 1 inch on all sides.

Indent new paragraphs by one-half inch.

Double-space the main text of your paper.

Single-space the footnotes and bibliography, but add a blank line between entries.

Start numbering your pages on the  second  page of your paper (don't include the title page).

Put your page numbers in the header of the first page of text (skip the title page), beginning with page number 1. Continue numbering your pages to the end of the bibliography.

Place the footnote number at the end of the sentence in which you have quoted or paraphrased information from another source. The footnote number should be in superscript, and be placed  after  any punctuation.

Put your footnotes in the footer section of the page.

Your research paper ends with a list of all the sources cited in the text of the paper. This is called a bibliography.

See an example in the "Sample Paper with Bibliography" box on this page.

Here are nine quick rules for this list:

• Start a new page for your bibliography (e.g. If your paper is 4 pages long, start your bibliography on page 5).
• Centre the title, Bibliography, at the top of the page and do not bold or underline it. Look for the alignment option in Word. 
• Leave two blank lines between the title and the first entry on your list.
• Single-space the list, but leave one blank line between entries.
• Start the first line of each citation at the left margin; each subsequent line should be indented (also known as a "hanging indent").
• Put your list in alphabetical order. Alphabetize the list by the first word in the citation. In most cases, the first word will be the author’s last name. Where the author is unknown, alphabetize by the first word in the title, ignoring the words a, an, the.
• For each author, give the last name followed by a comma and the first name followed by a period.
• Italicize the titles of full works , such as: books, videos (films and television shows), artwork, images, maps, journals, newspapers, magazines.
• Do not italicize titles of parts of works , such as: articles from newspapers, magazines, or journals / essays, poems, short stories or chapter titles from a book / chapters or sections of an Internet document. Instead, use quotation marks.

What Is An Annotated Bibliography?

An  annotated bibliography  is a list of citations for various books, articles, and other sources on a topic. The annotated bibliography looks like a Works Cited page but includes an annotation after each source cited. An annotation is a short summary and/or critical evaluation of a source. Annotated bibliographies can be part of a larger research project, or can be a stand-alone report in itself.

Types of Annotations

 A  summary annotation  describes the source by answering the following questions: who wrote the document, what the document discusses, when and where was the document written, why was the document produced, and how was it provided to the public. The focus is on description. 

 An  evaluative annotation  includes a summary as listed above but also critically assesses the work for accuracy, relevance, and quality. Evaluative annotations can help you learn about your topic, develop a thesis statement, decide if a specific source will be useful for your assignment, and determine if there is enough valid information available to complete your project. The focus is on description and evaluation.

• Cite the source using Chicago style.
• Describe the main ideas, arguments, themes, theses, or methodology, and identify the intended audience.
• Explain the author’s expertise, point of view, and any bias he/she may have.
• Compare to other sources on the same topic that you have also cited to show similarities and differences.
• Explain why each source is useful for your research topic and how it relates to your topic.
• Evaluate the strengths and weaknesses of each source.
• Identify the observations or conclusions of the author. 

Remember: Annotations are original descriptions that you create after reading the document. When researching, you may find journal articles that provide a short summary at the beginning of the text. This article abstract is similar to a summary annotation. You may consult the abstract when creating your evaluative annotation, but never simply copy it as that would be considered plagiarism. 

Tips on Writing & Formatting an Annotated Bibliography

• Each annotation should be one paragraph, between three to six sentences long (about 150- 200 words).
• Start with the same format as a regular Bibliography list.
• All lines should be double-spaced. Do not add an extra line between the citations.
• If your list of citations is especially long, you can organize it by topic.
• Try to be objective, and give explanations if you state any opinions.
• Use the third person (e.g., he, she, the author) instead of the first person (e.g., I, my, me)

Chicago Style Footnotes | Citation Format & Examples

Published on September 18, 2019 by Jack Caulfield . Revised on December 5, 2022.

The notes and bibliography style is one of two citation options provided by the Chicago Manual of Style . Each time a source is quoted or paraphrased , a superscript number is placed in the text, which corresponds to a footnote or endnote containing details of the source .

Footnotes appear at the bottom of the page, while endnotes appear on a separate page at the end of the text.

Pay attention to the punctuation (e.g., commas , quotation marks ) in your footnotes.

Table of contents

Full notes and short notes, placement of footnotes, content of chicago footnotes, footnote examples for different source types, footnotes vs endnotes, frequently asked questions about chicago style footnotes.

There are two types of footnote in Chicago style: full notes and short notes.

Full notes contain the full publication details of the source. The first citation of each source should be a full note.

Full note example

1. Virginia Woolf, “Modern Fiction,” in Selected Essays , ed. David Bradshaw (Oxford: Oxford University Press, 2008), 11.

Short notes contain only the author’s last name, the title (shortened if longer than four words), and the page number (if relevant). They are used for all subsequent citations of the same source. It’s also acceptable to use “ ibid. ” instead to refer to the immediately preceding source.

Short note example

2. Woolf, “Modern Fiction,” 11.

The guidelines for use of short and full notes can vary across different fields and institutions. Sometimes you might be required to use a full note for every citation, or to use a short note every time as long as all sources appear in the Chicago style bibliography . Check with your instructor if you’re unsure.

Here's why students love Scribbr's proofreading services

Discover proofreading & editing

Footnotes should be used whenever a source is quoted or paraphrased in the text. They appear at the bottom of the relevant page, corresponding to reference numbers in the text. You can easily insert footnotes in Microsoft Word .

The reference number appears in superscript at the end of the clause or sentence it refers to. It is placed after any punctuation except a dash :

Johnson argues that “the data is unconvincing.” 1

Johnson argues that “the data is unconvincing” 1 —but Smith contends that …

Notes should be numbered consecutively, starting from 1, across the whole text. Your first citation is marked with a 1, your second with a 2, and so on. The numbering does not restart with a new page or section (although in a book-length text it may restart with each new chapter).

The footnote contains the number of the citation followed by a period and then the citation itself. The citation always includes the author’s name and the title of the text, and it always ends with a period. Full notes also include all the relevant publication information in parentheses (which varies by source type ).

If you quote a source or refer to a specific passage, include a page number or range. However, if the source doesn’t have page numbers, or if you’re referring to the text as a whole, you can omit the page number.

In short notes, titles of more than four words are shortened. Shorten them in a way that retains the keyword(s) so that the text is still easily recognizable for the reader:

1. Mary Shelley, Frankenstein; or, the Modern Prometheus , ed. M.K. Joseph (Oxford: Oxford University Press, 1998), 91. 2. Shelley, Frankenstein , 91.

Combining multiple citations

Do not place multiple footnotes at the same point in your text (e.g. 1, 2, 3 ). If you need to cite multiple sources in one sentence, you can combine the citations into one footnote, separated by semicolons :

1. Hulme, “Romanticism and Classicism”; Eliot, The Waste Land ; Woolf, “Modern Fiction,” 11.

Sources with multiple authors

Footnotes for sources with two or three authors should include all the authors’ names. When there are four or more authors, add “ et al. ” (Latin for “and others”) after the first author’s name.

Missing information

You sometimes won’t have all the information required for your citation. You might be missing page numbers, the author’s name, or the publication date.

If one of your sources (e.g., a website ) has no page numbers, but you still think it’s important to cite a specific part of the text, other locators like headings , chapters or paragraphs can be used. Abbreviate words like “paragraph” to “par.” and “chapter” to “chap.”, and put headings in quotation marks :

1. Johnson, “Literature Review,” chap. 2.1 . 2. Smith, “Thematic Analysis,” under “Methodology.”

If the source lacks a stated publication date, the abbreviation “n.d.” (no date) should replace the year in a full note:

1. Smith, Data Analysis (New York: Norton, n.d. ), 293.

If a text doesn’t list its author’s name, the organization that published it can be treated as the author in your citation:

1. Scribbr , “Chicago Style Citation.”

If you use a website name as an author, you may end up repeating the same information twice in one citation. Omit the website name from its usual place if you’ve already listed it in place of the author.

Short notes usually look similar regardless of source type—author, title, page number. However, the information included in full notes varies according to the source you’re citing. Below are examples for several common source types, showing how the footnote should look in Chicago format .

Chicago book citation

Italicize the book title. If the book states an edition (other than the first), include this and abbreviate it (e.g., 2nd ed., rev. ed.). Add the URL if you consulted the book online instead of in a physical copy.

Chicago book chapter citation

Sometimes you’ll cite from one chapter in a book containing texts by multiple authors—for example, a compilation of essays. In this case, you’ll want to cite the relevant chapter rather than the whole book.

The chapter title should be enclosed in quotation marks , while the book title should be italicized. The short note only contains the chapter title.

The author is the one who wrote the specific chapter you’re citing. The editor of the whole book is listed toward the end of the footnote (with the abbreviation “ed.”), and left out of the short note.

Chicago journal article citation

The article title should be enclosed in quotation marks, while the journal name should be italicized. Volume and issue numbers identify which edition of the journal the source appears in.

A DOI is a digital object identifier. This is generally more reliable than the URL when linking to online journal content.

Chicago website citation

The page title should be enclosed in quotation marks. Italicization is not used for website names.

If the publication date is unknown, you can instead list the date when you accessed the page at the end of the citation (e.g., accessed on September 10, 2019).

All of the above information also applies to endnotes. Endnotes are less commonly used than footnotes, but they’re a perfectly valid option.

Footnotes appear at the bottom of the page they refer to.

• Footnotes allow the reader to immediately check your citations as they read …
• … but if you have a lot of footnotes, they can be distracting and take up space on the page.

Endnotes appear in their own section at the end of the text, before the bibliography.

• Endnotes take up less space in the body of your text and reduce distraction …
• … but they are less accessible, as the reader has to flip to the end to check each note.

Endnote citations look exactly the same as those in footnotes. Unless you’ve been told which one to use, choose whichever you prefer. Just use one or the other consistently.

Footnotes appear at the bottom of the relevant page.  Endnotes appear in a list at the end of the text, just before the reference list or bibliography. Don’t mix footnotes and endnotes in the same document: choose one or the other and use them consistently.

In Chicago notes and bibliography style , you can use either footnotes or endnotes, and citations follow the same format in either case.

In APA and MLA style , footnotes or endnotes are not used for citations, but they can be used to provide additional information.

In Chicago notes and bibliography style , the usual standard is to use a full note for the first citation of each source, and short notes for any subsequent citations of the same source.

However, your institution’s guidelines may differ from the standard rule. In some fields, you’re required to use a full note every time, whereas in some other fields you can use short notes every time, as long as all sources are listed in your bibliography . If you’re not sure, check with your instructor.

In Chicago author-date style , your text must include a reference list . It appears at the end of your paper and gives full details of every source you cited.

In notes and bibliography style, you use Chicago style footnotes to cite sources; a bibliography is optional but recommended. If you don’t include one, be sure to use a full note for the first citation of each source.

Page numbers should be included in your Chicago in-text citations when:

• You’re quoting from the text.
• You’re paraphrasing a particular passage.
• You’re referring to information from a specific section.

When you’re referring to the overall argument or general content of a source, it’s unnecessary to include page numbers.

In a Chicago style footnote , list up to three authors. If there are more than three, name only the first author, followed by “ et al. “

In the bibliography , list up to 10 authors. If there are more than 10, list the first seven followed by “et al.”

The same rules apply in Chicago author-date style .

From the chicago manual of style, chicago-style epigraphs and sources ( cmos 1.37).

Section  1.37  in the Spotlight

An epigraph is a short quotation at the beginning of a book or chapter or article that sets the tone for what’s to come. It’s often from a famous source, but it doesn’t have to be.

The source of an epigraph is usually given on a line following the quotation, sometimes preceded by a dash. Only the author’s name and, usually, the title of the work need appear; it is not customary to give a full citation (but see  14.52 ).

Epigraphs are treated like block quotations in that quotation marks are not used around epigraphs. Also like block quotations, epigraphs are often set in a smaller typeface and indented from the right or left, and sometimes italicized.

Oh, what a tangled web we weave, When first we practice to deceive! —Sir Walter Scott

It is a truth universally acknowledged, that a single man in possession of a good fortune, must be in want of a wife. Jane Austen,  Pride and Prejudice
