How to Do Chicago Style Footnotes / Endnotes: Format & Examples

Have you noticed numbers in documents after a sentence and then at the bottom of a page? Of course, everyone has come across footnotes. What is it about in the Chicago manual of style, footnotes?

A footnote is an additional information/comment that is placed at the bottom of a page. In this way, you can provide readers with additional information and cite a source that contains full information used in the current text.

To indicate footnotes in the text, use an index. Footnotes must be numbered consecutively throughout a document. They are used both in academic documents and in newspapers, books, and scholarly publications.

So what does it look like? Here is a simple example of a footnote format. 

Footnote Citation Example 

There is also an endnote, which also should be marked in text with the superscript number. Unlike footnotes, Chicago style endnotes are usually placed at the end of a document, chapter, or paper. They are used to provide additional information in a particular section of a document. 

Endnotes are often used in academic writing for additional information and citation sources. Using endnotes is a better option if you have too many references and don’t want to staff your page with notes. This way, you won’t distract readers from reading your paper. Like footnotes, endnotes should be numbered consistently throughout the document and correspond to a superscript number in the text.

It is vital to understand that both footnotes and endnotes are used to provide additional information and link to a resource in text. What is the difference between footnotes and endnotes? The key difference between these referencing methods is where they are used in text.

Footnotes are typically placed at the bottom of the page on which a specific citation or reference is mentioned. They are used to provide clarifications on sources that can be quickly accessed by readers. Endnotes, on the other hand, are located at the end of a paper or publication. By providing notes in a separate area, you won’t disturb readers with excessive citations. 

As for which choice to make, it is necessary to take into account the requirements of a publisher and consider the amount of citations you will make. However, footnotes are more commonly used when talking about Chicago Style, as this is an opportunity for readers to immediately obtain more details on a resource you linked to.

Without further ado, let's discuss how to do footnotes in Chicago style 17th edition.

Chicago footnote citation format offers two types of notes – full notes  and short notes. When to use each type? Full notes provide complete bibliographic information and are utilized when a source is mentioned for the first time. Short notes are used when you need to indicate a source that has already been mentioned. In this case, you will indicate less details on a publication. 

To create a full note, you need to specify all details essential to identify the source. Include the author's name, title of the work, publication information, and page numbers. Here is an example designed for a book. 

Full Note Example

In this example, the full note includes the author's name, the full title and subtitle of the book, place and date of publication, and precise page range where the referenced ideas can be found.

Now, let’s imagine that you need to create a subsequent Chicago footnote citation for the same source. In this case, you will include a short note listing only the author's name,  shortened title of this book, and page numbers. Here’s an example. 

Short Note Example 

As you can see, using short notes can help to reduce repetition and clutter in a paper or document.

Now, let’s figure out how to properly place footnotes. 

In Chicago Style, a superscript number should not disrupt the overall coherence of your text. Insert a footnote number at a point where the idea being cited appears complete, be it the end of clause or entire sentence. This will establish a logical flow and make it easy for readers to understand the context of the citation.

Let’s take a look at these 2 examples. 

Superscript at the End of a Sentence 

Here, the superscript number is placed after the period that follows "destruction," indicating that the citation pertains to the entire sentence.

Superscript at the End of a Clause

In this case, a paper writer implies that the reference links to the information preceding the footnote.

There are 2 ways students can use to insert a footnote – before or after punctuation. 

According to Chicago style guidelines, footnotes should be incorporated directly after all punctuation marks, including period, comma, quotation marks, colons and semicolons. The only exception is the dash, which should be followed by the footnote number.
