Footnote Citation Guide: Research Tips & Examples

Footnote — What It Is and Why It Matters

A footnote is a short note placed at the bottom of the page that provides extra information, citation details, or copyright attribution about content in your paper. Each footnote is marked by a small superscript number in the main text that links to the corresponding note in the footer of the page.

Footnotes are used when you want to:

• Include a citation for a source without disrupting your main text.
• Add clarifications or extra discussion related to your quotation or idea.
• Insert copyright information or permission notes for borrowed materials.

Example:

According to the data, early trade routes shaped global culture¹.

¹ John Smith, History of Commerce (New York: Academic Press, 2021), 45.

This is known as a footnote example, and the style depends on whether you are using APA style, MLA style, or Chicago style.

Citation — How to Cite Using Footnotes

A citation is a formal way to credit the source of your ideas, facts, or quotes. Footnotes act as mini-citations.

In the Chicago Manual of Style, which uses the notes and bibliography system, footnotes and endnotes replace in-text citations. They help you list the author’s name, title of the work, page number, and publication details.

How do you do footnote citations?

1. Place a superscript number after the sentence or quotation that needs a source.
2. Add a corresponding note in the footer.
3. Include full source details the first time, and a short form later.

Example:

“Trade defines civilisation.”²

² Jane Doe, World Economics (Oxford: OUP, 2022), 67.

To simplify, you can copy and paste the citation or click “Insert Footnote” in Word.

APA — Footnotes in APA Style

In APA style, footnotes are less common than in Chicago or MLA. APA typically uses in-text citations with parentheses. However, footnotes may still appear in an APA paper when providing extra commentary or explaining complex data.

APA footnotes are formatted as:

• Single-spaced
• Indented
• Numbered sequentially
• Placed at the bottom of the relevant page

Example:

The results show consistent variation across regions.³

³ See Appendix A for regional breakdowns and supporting tables.

To include appendices, you must also know how to create appendices in APA format. They appear at the end of the document or as an appendix paper, each on a separate page titled “Appendix.”

Endnotes — What They Are and How They Differ

Endnotes serve the same function as footnotes but are placed at the end of a chapter or the end of the document instead of the footer.

Footnotes vs Endnotes:

• Footnotes appear at the bottom of each page.
• Endnotes appear collectively at the end of the text.
• Both include citations or commentary, depending on your citation style.

If your research guides or university require endnotes, you can easily switch in Word by choosing “Convert to Endnotes.”

Style Footnotes — Chicago, APA, and MLA Compared

Each citation style has its own footnote format.

1. Chicago Style Footnotes

• Used in the notes and bibliography style.
• Common in history, theology, and arts.
• A Chicago style footnotes example: ¹ John Doe, The Art of Commerce (London: Routledge, 2020), 112, https://doi.org/10.1007/example.

2. APA Style

• Uses parenthetical in-text citation instead of footnotes for sources.
• Footnotes are mainly for explanation, not referencing.

3. MLA Style

• Uses in-text citations and a Works Cited page.
• MLA source maker tools can help format the entries automatically.

Each of these depends on your source type — a book, journal, website, or database.

Source Type — How It Shapes Your Footnote

Your source type determines how to structure your footnote or bibliography entry:

If your source includes a digital object identifier (DOI), always include it at the end of the citation.

Table of Contents — Linking Footnotes and References

When writing a long thesis or report, your table of contents lists chapters, appendices, and footnotes page if you have many notes. Each footnote connects readers to the correct page number or appendix in APA format.

Tips:

• Keep the numbering consistent.
• Align your notes with the content or copyright information they support.
• If you use appendices, mention them in both the text and the table of contents.

Cite — How to Add and Manage Footnotes

Here is a step-by-step on how to add footnotes in Microsoft Word:

1. Click where you want the note number.
2. Go to References > Insert Footnote.
3. Type your footnote text at the bottom of the page.
4. Use indentation and proper punctuation.

To cite footnotes properly:

• Ensure each note corresponds with an in-text superscript number.
• Include page numbers when quoting directly.
• If paraphrasing, note “According to the source…” to guide your reader.

Bibliography — The Final List of Sources

At the end of your paper, include a bibliography or “References” page on a separate page.

• It lists every source cited in your footnotes.
• Entries are arranged alphabetically by author’s name.
• Each citation ends with a period, and the second line is indented.

Example:

Clark, Susan. Urban Planning. New York: Springer, 2024.
Doe, Jane. Modern Ethics. Cambridge: CUP, 2023.

You can use a free citation generator or follow research guides from Purdue University to double-check formatting.

Chicago Style — Notes and Bibliography System

The Chicago Manual of Style supports two systems:

1. Notes and Bibliography Style (uses footnotes and a bibliography).
2. Author-Date Style (uses in-text citations).

For humanities subjects, the Chicago notes and bibliography style is the most common.

Key components:

• Footnotes appear at the bottom of each page.
• Numbers in the text correspond to those notes.
• A bibliography lists all sources in footnotes alphabetically.

Quotation — When to Use Footnotes for Quotes

When quoting or paraphrasing, citation is needed to avoid plagiarism.

Rules:

• Enclose direct quotes in quotation marks.
• Insert the superscript number right after the punctuation.
• Include the page number in the footnote.
• Paraphrased content still requires a source.

Example:

“Global trade reshaped identity.”⁴

⁴ Clark, Urban Planning, 88.

Footnotes and Endnotes — Which One Should You Use?

Footnotes or Endnotes? It depends on the citation style and your discipline.

• If your paper follows Chicago style, use footnotes and a bibliography.
• If your field prefers minimal interruptions in text, endnotes may be better.
• Both should correspond with a bibliography at the end.

Each footnote contains all information relevant to the source type, such as the author’s name, title of the work, page number, and DOI or URL.

Example of including a DOI in a Chicago footnote:

¹ Emily Green, “Trade and Sustainability,” Journal of Economics 11, no. 3 (2023): 45, https://doi.org/10.2458/je.2023.88.

If a DOI is unavailable, include a URL or the name of the database instead.

   • Often used for side remarks, context, or additional insights.
   • Example: For a deeper discussion on early trade policies, see the extended analysis by Smith (2023).
2. Copyright or Permission Footnotes
   • Provide copyright information or note permission from the copyright owner.
   • Common in research including images, tables, or long quotations enclosed in quotation marks.
3. Reference or Citation Footnotes
