What Is Chicago Referencing?
Understand Chicago’s two citation systems before formatting any source.
If you are studying history, humanities, social sciences, arts, theology, cultural studies, or related academic subjects, there is a strong possibility that your university may require Chicago referencing.
Chicago Style is one of the most respected and widely used citation systems in higher education. Developed by the University of Chicago Press, it is based on the Chicago Manual of Style, a comprehensive guide that has been used by academics, researchers, publishers, and students for more than a century.
Unlike Harvard, APA, and MLA, Chicago offers two different citation systems. This flexibility allows students and researchers to choose the method that best suits their discipline and assignment requirements.
Understanding Chicago referencing can help students present research professionally, avoid plagiarism, and demonstrate strong academic writing skills.

What Is Chicago Style Referencing?
Chicago referencing is a citation style that provides rules for citing sources within academic writing and creating bibliographies or reference lists.
The Chicago system includes two approaches:
Notes and Bibliography
This system uses footnotes or endnotes alongside a bibliography.
It is commonly used in:
History
Literature
Arts
Humanities
Theology
Author-Date
This system uses in-text citations similar to Harvard and APA.
It is commonly used in:
Social Sciences
Business
Environmental Studies
Some interdisciplinary subjects
Students should always check their university guidelines to determine which Chicago system is required.
Who Created Chicago Style?
Chicago Style was developed by the University of Chicago Press.
The first edition of the Chicago Manual of Style was published in 1906.
Since then, it has become one of the most influential academic style guides in the world.
Today, students and researchers across numerous disciplines use Chicago referencing to present scholarly work consistently and professionally.
Students who wish to review official guidance can consult the Chicago Manual of Style Online.
Why Do Universities Use Chicago Referencing?
Chicago Style offers flexibility and detailed citation guidance.
Universities use Chicago referencing because it:
Promotes academic integrity
Provides detailed source information
Supports complex research projects
Allows precise source tracking
Helps prevent plagiarism
Maintains consistency in academic writing
Because Chicago can handle a wide variety of source types, it is particularly useful for dissertations, research papers, and historical studies.
Which Subjects Use Chicago Referencing?
Chicago Style is commonly used across a range of disciplines.
History
Historical research often relies heavily on footnotes and archival sources, making Chicago particularly suitable.
Humanities
Literature, philosophy, religion, and cultural studies frequently use Chicago Style.
Theology
Religious studies and theological research commonly require Chicago citations.
Arts and Fine Arts
Art history, visual culture, and creative research projects often use Chicago referencing.
Social Sciences
Some social science programmes use Chicago’s Author-Date system.
Cultural Studies
Research involving media, culture, identity, and society may also use Chicago Style.
Interdisciplinary Research
Many postgraduate and doctoral projects use Chicago because of its flexibility.
The Two Chicago Citation Systems
One of the most distinctive features of Chicago referencing is that it offers two citation systems.
Understanding the difference is important because universities usually require one specific version.
Notes and Bibliography System
The Notes and Bibliography system uses footnotes or endnotes.
Example
Recent studies suggest leadership communication significantly influences employee engagement.¹
Footnote
¹ Peter Wilson, Modern Leadership (London: Pearson, 2024), 25.
A bibliography at the end of the assignment provides full source details.
Bibliography Entry
Wilson, Peter. Modern Leadership. London: Pearson, 2024.
This system is most common in history and humanities subjects.
Author-Date System
The Author-Date system uses in-text citations.
Example
Recent studies suggest leadership communication significantly influences employee engagement (Wilson 2024, 25).
A reference list appears at the end of the document.
Reference List Entry
Wilson, Peter. 2024. Modern Leadership. London: Pearson.
This system is more common in social science disciplines.
How Is Chicago Different From Harvard Referencing?
At first glance, Chicago Author-Date may look similar to Harvard.
Harvard Example
(Wilson 2024)
Chicago Author-Date Example
(Wilson 2024, 25)
Chicago often includes page numbers directly within citations.
In addition, Chicago offers the Notes and Bibliography system, which Harvard does not.
How Is Chicago Different From APA Referencing?
APA uses author-date citations and follows strict formatting rules.
APA Example
(Wilson, 2024, p. 25)
Chicago Author-Date Example
(Wilson 2024, 25)
Although similar, the formatting differs significantly.
APA is most common in psychology, education, and social sciences, whereas Chicago is more common in history and humanities disciplines.
How Is Chicago Different From MLA Referencing?
MLA uses author-page citations.
MLA Example
(Wilson 25)
Chicago Example
(Wilson 2024, 25)
Chicago includes the publication year, while MLA focuses primarily on page numbers.
Why Is Accurate Chicago Referencing Important?
Correct referencing helps students:
Acknowledge original authors
Support academic arguments
Demonstrate research skills
Avoid plagiarism
Improve academic credibility
Meet university requirements
Accurate citations also allow readers to verify information and explore sources further.
Common Sources Referenced in Chicago Style
Students frequently use Chicago referencing for:
Books
Academic books, textbooks, and scholarly publications.
Journal Articles
Peer-reviewed research and academic studies.
Websites
Educational resources, reports, and online publications.
Newspapers
Current affairs and historical reporting.
Government Reports
Official statistics, policy documents, and research reports.
Theses and Dissertations
Postgraduate and doctoral research.
Interviews
Personal communications and recorded discussions.
Films and Documentaries
Visual media and cultural sources.
AI Tools
Where permitted by institutional policy.
Why Students Struggle With Chicago Referencing
Students often find Chicago confusing because it includes two citation systems.
Common challenges include:
Choosing the correct system
Formatting footnotes
Creating bibliographies
Using page numbers correctly
Referencing websites
Formatting journal articles
Understanding footnote conventions
Once students understand the structure of Notes and Bibliography or Author-Date, Chicago becomes much easier to apply consistently.
Using a Chicago Citation Generator
Creating Chicago citations manually can be time-consuming, especially when working with multiple books, journal articles, websites, reports, and research sources.
A Chicago Citation Generator can help students create:
Footnotes
Bibliography entries
In-text citations
Reference list entries
Book citations
Website references
Journal article citations
more efficiently.
Students should always review generated citations carefully before submission to ensure they meet university requirements.
How Chicago Referencing Works
Select a topic to compare Notes and Bibliography with Author-Date, then review footnotes, shortened citations, source lists, and common mistakes.
One of the reasons Chicago Style remains popular in universities is its flexibility. Unlike most citation systems, Chicago offers two different methods for citing sources.
Students can use either:
Notes and Bibliography
Author-Date
depending on their subject and university requirements.
Understanding how these systems work is the key to applying Chicago referencing correctly.
The Basic Principle of Chicago Referencing
Whenever you use information, ideas, research findings, quotations, or arguments from another source, you should provide a citation.
Chicago citations help readers:
Identify your sources
Verify information
Locate original materials
Follow your research trail
The exact format depends on which Chicago system is being used.
Chicago Notes and Bibliography System
The Notes and Bibliography system is most commonly used in:
History
Literature
Humanities
Theology
Arts
Instead of using in-text citations, sources are cited using footnotes or endnotes.
Example
Historical evidence suggests communication played a crucial role in political leadership.¹
Footnote
¹ Peter Wilson, Modern Leadership (London: Pearson, 2024), 25.
Bibliography Entry
Wilson, Peter. Modern Leadership. London: Pearson, 2024.
The footnote provides source information immediately, while the bibliography provides complete publication details.
What Are Footnotes?
Footnotes appear at the bottom of a page and provide citation details.
Example
Text:
Effective communication remains a key leadership skill.¹
Footnote:
¹ Peter Wilson, Modern Leadership (London: Pearson, 2024), 25.
Footnotes allow readers to identify sources without interrupting the flow of the main text.
What Are Endnotes?
Endnotes function similarly to footnotes but appear together at the end of a chapter or document rather than at the bottom of each page.
Most university assignments use footnotes, although some lecturers may allow endnotes.
Chicago Author-Date System
The Author-Date system is commonly used in:
Social Sciences
Business
Environmental Studies
Interdisciplinary Research
This system uses in-text citations.
Example
Effective communication remains a key leadership skill (Wilson 2024, 25).
The full source information appears in a reference list.
Reference List Entry
Wilson, Peter. 2024. Modern Leadership. London: Pearson.
When Should Students Use Notes and Bibliography?
Notes and Bibliography is usually preferred when assignments rely heavily on:
Historical sources
Archival materials
Primary documents
Detailed source commentary
It provides greater flexibility for discussing sources within footnotes.
When Should Students Use Author-Date?
Author-Date is generally preferred when assignments involve:
Research studies
Data analysis
Social science research
Quantitative evidence
This approach keeps citations concise while still providing clear source information.
Chicago Footnotes Example
Imagine you are writing a history essay.
Text
The Industrial Revolution transformed economic structures across Europe.¹
Footnote
¹ John Smith, Economic Change in Europe (Oxford: Oxford University Press, 2022), 47.
Bibliography
Smith, John. Economic Change in Europe. Oxford: Oxford University Press, 2022.
This is the standard Notes and Bibliography approach.
Chicago Author-Date Example
The same source would appear differently using Author-Date.
Text
The Industrial Revolution transformed economic structures across Europe (Smith 2022, 47).
Reference List
Smith, John. 2022. Economic Change in Europe. Oxford: Oxford University Press.
Shortened Footnotes
Chicago allows shortened footnotes after a source has already been cited.
First Footnote
¹ Peter Wilson, Modern Leadership (London: Pearson, 2024), 25.
Later Footnote
² Wilson, Modern Leadership, 48.
This helps reduce repetition in longer assignments.
Using Multiple Sources
Students often need to support a statement with multiple sources.
Example
Several researchers have reached similar conclusions regarding leadership effectiveness.¹ ² ³
Each footnote refers to a separate source.
Chicago Bibliographies
A bibliography appears at the end of the document.
It provides complete details of all sources cited throughout the assignment.
Typical bibliography entries include:
Books
Journal articles
Websites
Reports
Newspapers
Interviews
Theses
Films
The bibliography allows readers to locate original sources easily.
Bibliography vs Reference List
The terminology depends on which Chicago system is being used.
Notes and Bibliography
Uses:
Footnotes

Chicago Footnotes Guide With Examples
Select a topic to review full and shortened footnotes for books, articles, websites, reports, newspapers, videos, dissertations, quotations, and paraphrases.
Footnotes are one of the defining features of Chicago Style’s Notes and Bibliography system. They allow students to provide source information without disrupting the flow of their writing.
Chicago footnotes are commonly used in:
History essays
Humanities assignments
Literature studies
Theology research
Arts and cultural studies
Dissertations and theses
Understanding how footnotes work is essential for using Chicago referencing correctly.
What Is a Chicago Footnote?
A footnote is a citation that appears at the bottom of the page.
A superscript number is placed within the text, and the corresponding citation appears below.
Example
Leadership communication played a significant role in organisational success.¹
Footnote
¹ Peter Wilson, Modern Leadership (London: Pearson, 2024), 25.
The footnote provides the source details while keeping the main text easy to read.
When Should Footnotes Be Used?
A footnote should normally be added whenever you:
Use someone else’s ideas
Quote directly
Paraphrase information
Refer to research findings
Mention statistics
Discuss historical facts
Cite a source
Proper footnoting helps maintain academic integrity and avoid plagiarism.
Where Does the Footnote Number Go?
The superscript footnote number should normally appear after punctuation.
Correct
Effective communication improves leadership performance.¹
Incorrect
Effective communication improves leadership performance¹.
Consistency is important throughout the assignment.
First Footnote Citation for a Book
The first time a source is cited, Chicago generally requires full publication details.
Format
Author First Name Last Name, Book Title (Place of Publication: Publisher, Year), Page Number.
Example
¹ Peter Wilson, Modern Leadership (London: Pearson, 2024), 25.
First Footnote Citation for a Journal Article
Format

First Footnote Citation for a Dissertation
Format
Author First Name Last Name, Title (Degree diss., University, Year), Page Number.
Example
¹ Peter Wilson, Improving Employee Engagement Through Leadership Strategies (PhD diss., University of Manchester, 2025), 88.
Shortened Footnotes
After a source has been cited once, Chicago allows a shorter version in later footnotes.
First Citation
¹ Peter Wilson, Modern Leadership (London: Pearson, 2024), 25.
Later Citation
² Wilson, Modern Leadership, 48.
This keeps footnotes concise and avoids repetition.
Using "Ibid."
Some universities still allow the use of "Ibid."
"Ibid." means "in the same place" and refers to the immediately preceding source.
Example
¹ Peter Wilson, Modern Leadership (London: Pearson, 2024), 25.
² Ibid., 30.
However, many institutions now prefer shortened citations instead of repeated use of "Ibid."
Students should check their university guidance.
Footnotes for Direct Quotations
Direct quotations should include specific page numbers.
Example
According to Wilson, "effective leadership begins with communication."¹
Footnote
¹ Peter Wilson, Modern Leadership (London: Pearson, 2024), 45.
Page numbers help readers locate the exact quotation.
Footnotes for Paraphrased Information
Footnotes are also required when paraphrasing.
Example
Research suggests that employee engagement improves organisational performance.¹
Footnote
¹ Peter Wilson, Modern Leadership (London: Pearson, 2024), 52.
Even though the wording has changed, the original source should still be acknowledged.
Multiple Sources in Footnotes
Sometimes multiple sources support the same statement.
Example
Several researchers have reached similar conclusions regarding workplace communication.¹ ² ³
Each source receives its own footnote.
Common Chicago Footnote Mistakes
Students frequently lose marks because of avoidable footnote errors.
Missing Page Numbers
Page numbers should normally be included where relevant.
Incomplete Publication Information
Provide sufficient details for readers to locate the source.
Inconsistent Formatting
Apply the same Chicago style throughout the assignment.
Missing Footnotes
Every borrowed idea should normally have a citation.
Mixing Chicago With Harvard
Do not combine footnotes with Harvard-style author-date citations unless specifically required.
Footnotes vs Bibliography Entries
Students often notice that footnotes and bibliography entries look slightly different.
Footnote Example
¹ Peter Wilson, Modern Leadership (London: Pearson, 2024), 25.
Bibliography Example
Wilson, Peter. Modern Leadership. London: Pearson, 2024.
Chicago intentionally formats these elements differently.
Why Footnotes Are Useful
Footnotes offer several advantages.
They:
Keep writing uncluttered
Allow detailed citations
Support historical research
Improve source transparency
Help readers verify information
This is one reason why Chicago Style remains popular in humanities and historical research.

Why Examples Matter
Many students understand referencing rules in theory but struggle when applying them to real sources.
Reviewing examples can help students:
Format citations correctly
Avoid common mistakes
Understand source differences
Improve consistency
Build confidence when referencing
When in doubt, compare your citation to a trusted Chicago example before submission.
Common Chicago Referencing Mistakes and How to Avoid Them
Review system mixing, missing citations, page numbers, author order, italics, URLs, shortened footnotes, and source-list errors.
Chicago Style is one of the most flexible citation systems used in higher education. However, because it offers two different citation methods, many students become confused and make avoidable referencing mistakes.
Understanding these common errors can help improve the accuracy, professionalism, and credibility of academic work.
Mixing Chicago Systems
One of the most common mistakes is mixing the two Chicago citation systems.
Students sometimes use:
Footnotes from Notes and Bibliography
In-text citations from Author-Date
within the same assignment.
Incorrect
Recent research supports this conclusion.¹
(Wilson 2024, 25)
Correct
Choose one system and use it consistently throughout the document.
Missing Footnotes
Students using the Notes and Bibliography system sometimes forget to add footnotes.
Example
Leadership communication improves employee engagement.
If the information comes from a source, a footnote should normally be added.
Correct
Leadership communication improves employee engagement.¹
Missing citations can create plagiarism concerns.
Missing Page Numbers
Chicago citations often require page numbers when referencing specific information.
Incorrect
¹ Peter Wilson, Modern Leadership (London: Pearson, 2024).
Better
¹ Peter Wilson, Modern Leadership (London: Pearson, 2024), 25.
Page numbers help readers locate the exact material being discussed.
Incorrect Footnote Formatting
Chicago footnotes follow a specific structure.
Correct
¹ Peter Wilson, Modern Leadership (London: Pearson, 2024), 25.
Incorrect
¹ Wilson, Peter. Modern Leadership. London: Pearson, 2024.
Footnotes and bibliography entries use different formats.
Confusing Footnotes and Bibliography Entries
Many students copy bibliography entries directly into footnotes.
Footnote
¹ Peter Wilson, Modern Leadership (London: Pearson, 2024), 25.
Bibliography
Wilson, Peter. Modern Leadership. London: Pearson, 2024.
The two formats are intentionally different.
Missing Bibliography Entries
Every source cited in footnotes should normally appear in the bibliography.
Students sometimes:
Include footnotes
Forget bibliography entries
This creates inconsistencies in the referencing system.
Incorrect Author Formatting
Bibliographies require author names to be reversed.
Correct Bibliography
Wilson, Peter.
Incorrect Bibliography
Peter Wilson.
The reversed format supports alphabetical organisation.
Incorrect Alphabetical Order
Bibliographies should generally be organised alphabetically.
Correct
Brown, Thomas.
Jones, Sarah.
Wilson, Peter.
Incorrect
Sources listed randomly.
Alphabetical organisation helps readers locate sources efficiently.
Missing Italics
Students often forget to italicise major works.
Titles that are usually italicised include:
Books
Journals
Newspapers
Films
Websites
Correct
Modern Leadership
Incorrect
Modern Leadership
Incomplete Publication Details
Bibliography entries should contain sufficient information for readers to locate the source.
Missing Information Examples
Publisher
Publication year
Place of publication
Journal volume
Issue number
Always provide complete publication details where available.
Incorrect Website Citations
Website references frequently contain errors.
Common problems include:
Missing publication dates
Missing page titles
Missing website names
Broken URLs
Correct
NHS. "Healthy Eating Advice." NHS. January 15, 2025. https://www.nhs.uk.
Using Broken URLs
Before submission:
Test every link
Verify webpages exist
Confirm URLs are accurate
Broken links reduce the usefulness of references.
Incorrect Journal Article Formatting
Journal articles require specific details.
Correct
Wilson, Peter. "Employee Wellbeing and Organisational Performance." Journal of Business Research 42, no. 3 (2024): 120-135.
Common Errors
Missing volume numbers
Missing issue numbers
Missing page ranges
Missing publication year
Incorrect Use of Shortened Footnotes
Chicago allows shortened citations after the first full citation.
First Citation
¹ Peter Wilson, Modern Leadership (London: Pearson, 2024), 25.
Later Citation
² Wilson, Modern Leadership, 48.
Students sometimes repeat full citations unnecessarily throughout the document.
Overusing "Ibid."
Some universities discourage excessive use of "Ibid."
While acceptable in certain situations, shortened footnotes are often preferred.
Students should follow their institution’s guidance.
Mixing Chicago and Harvard Referencing
This is a frequent problem among students who use multiple citation styles.
Harvard
(Wilson 2024)
Chicago Author-Date
(Wilson 2024, 25)
Chicago Footnote
¹ Peter Wilson, Modern Leadership (London: Pearson, 2024), 25.
Each style follows different rules and should not be mixed.
Chicago vs Harvard Referencing
(Wilson 2024)
Chicago Author-Date
(Wilson 2024, 25)
Chicago Notes and Bibliography
¹ Peter Wilson, Modern Leadership (London: Pearson, 2024), 25.
Chicago provides more flexibility because it supports both citation systems.
Chicago vs APA Referencing
(Wilson, 2024, p. 25)
Chicago
(Wilson 2024, 25)
Although similar, punctuation and formatting differ considerably.
Chicago vs OSCOLA Referencing
Chicago and OSCOLA both use footnotes, but their formats are different.
OSCOLA
¹ Donoghue v Stevenson [1932] AC 562 (HL).
Chicago
¹ Peter Wilson, Modern Leadership (London: Pearson, 2024), 25.
OSCOLA is primarily used in law, while Chicago is commonly used in humanities and history.
When Students Need Chicago Referencing Help
Students frequently seek assistance when working on:
History essays
Humanities assignments
Literature reviews
Dissertations
Research papers
Postgraduate projects
Thesis writing
Longer assignments often contain dozens of footnotes and bibliography entries, making accuracy particularly important.
Chicago Referencing Tips for Better Marks
A few simple habits can significantly improve referencing accuracy.
Keep Research Notes
Record source details while researching.
Check Citations Immediately
Add citations while writing rather than later.
Review Footnotes
Verify page numbers and formatting.
Review Bibliography Entries
Ensure consistency throughout.
Proofread Carefully
Small punctuation errors can affect Chicago formatting.
Chicago Mistakes Checklist

Only one Chicago system is being used.
Footnotes are formatted correctly.
Page numbers are included where necessary.
Bibliography entries are complete.
Author names are formatted correctly.
Sources are alphabetised.
URLs are working.
Italics are used correctly.
Harvard and APA formatting have not been mixed into the document.
Chicago style is applied consistently throughout.
Following these checks can help students avoid the most common Chicago referencing mistakes and submit more professional academic work.
Chicago Referencing Rules Students Should Know
Use one Chicago system consistently. Open each rule to check citations, footnotes, source-list formatting, DOI links, URLs, and university requirements.
Chicago Style offers flexibility, but that flexibility can sometimes lead to confusion. Whether you are using the Notes and Bibliography system or the Author-Date system, following the correct rules is essential for accurate and professional referencing.
The following guidelines cover the most important Chicago referencing rules that students should know.
Choose One Chicago System
Chicago provides two citation systems:
Notes and Bibliography
Author-Date
Rule
Use only one system throughout the assignment.
Incorrect
Using footnotes in some sections and author-date citations in others.
Correct
Use the same Chicago system consistently from beginning to end.
Use Footnotes Correctly
For Notes and Bibliography assignments, sources should normally be cited using footnotes.
Example
Leadership communication improves employee engagement.¹
Footnote
¹ Peter Wilson, Modern Leadership (London: Pearson, 2024), 25.
Place Footnote Numbers After Punctuation
Leadership communication improves employee engagement.¹
Incorrect
Leadership communication improves employee engagement¹.
Footnote numbers should normally appear after the punctuation mark.
Include Page Numbers Where Relevant
When referring to a specific idea, quotation, or section, include page numbers.
Example
¹ Peter Wilson, Modern Leadership (London: Pearson, 2024), 25.
Page numbers help readers locate the original source material.
Use Full Citations the First Time
The first citation of a source should contain complete publication details.
Example
¹ Peter Wilson, Modern Leadership (London: Pearson, 2024), 25.
Use Shortened Footnotes After the First Citation
After the first citation, Chicago allows shortened versions.
First Citation
¹ Peter Wilson, Modern Leadership (London: Pearson, 2024), 25.
Later Citation
² Wilson, Modern Leadership, 48.
This helps reduce repetition.
Use a Bibliography
Most Notes and Bibliography assignments require a bibliography.
Every source cited in footnotes should normally appear in the bibliography.
Arrange Bibliography Entries Alphabetically
Brown, Thomas.
Jones, Sarah.
Wilson, Peter.
Entries should normally be organised alphabetically by surname.
Reverse Author Names in the Bibliography
¹ Peter Wilson, Modern Leadership (London: Pearson, 2024), 25.
Bibliography
Wilson, Peter. Modern Leadership. London: Pearson, 2024.
Notice that the author’s name is reversed in the bibliography.
Use Hanging Indents
Bibliography entries should use hanging indents.
Example
Wilson, Peter. Modern Leadership and Organisational Success. London:Pearson, 2024.
Italicise Major Works
Titles of major works should generally be italicised.
Examples include:
