The Internet is a great resource for students, but websites can be difficult to cite correctly. Find out how to cite a website in three major style guides.
While reading a book or article, have you ever noticed little numbers placed at the ends of some sentences?
These numbers usually appear as superscripts and correspond with numbers placed at the bottom of the page, next to which appears further information that is both necessary and supplementary. Sometimes this information will come in the form of citations, but sometimes it will simply present additional notes about the topic at hand.
These citations and explanations are called footnotes (because they appear in the footer of the page). Take a look at the example below to see where footnotes appear on a page:
What Are Footnotes?
Long explanatory notes can be difficult for readers to trudge through when they occur in the middle of a paper. Providing this information is necessary, but doing so in the main text can disrupt the flow of the writing. Imagine if every time an author wanted to provide a citation, the entire citation had to be written out at the end of the sentence, like this (Anthony Grafton, The Footnote: A Curious History [Cambridge, MA: Harvard University Press, 1999] 221). Books would become much longer and reading much more tedious. That's why footnotes are so useful: they allow authors to provide the required information without disrupting the flow of ideas.
Footnotes can include anything from a citation to parenthetical information, outside sources, copyright permissions, background information, and anything in between, though certain style guides restrict when footnotes can be used. We'll get into that soon!
Footnotes vs. Endnotes
Authors can also use endnotes to avoid disrupting their writing with extraneous information. As with footnotes, the presence of an endnote is identified in the main text with a small superscript number. However, instead of providing the correlating note at the bottom of the same page, endnotes are found collectively at the end of an article, chapter, or document. Makes sense, right?
When deciding whether to use footnotes or endnotes, authors must consider three main factors: 1) the style guide being used (as some require the use of one or the other, 2) the number of notes being included (as having too many footnotes on each page can be distracting), and 3) which will be more convenient for the reader.
How to Use Footnotes
Of the major style guides, The Chicago Manual of Style (CMS) uses footnotes most often. However, footnotes are occasionally employed in other style guides as well. The main difference is that, while CMS uses footnotes for citation purposes, the Modern Language Association (MLA) and the American Psychological Association (APA) generally rely on them for the provision of additional information.
Modern Language Association (MLA)
While MLA style discourages the use of long footnotes or endnotes, the style guide does permit their use for directing readers to other pertinent information on a relevant subject.
The guide recommends that superscript numbers within the text are placed outside any punctuation that might be present (i.e., after a period if the note is at the end of a sentence and after a comma if the note is at the end of a clause). The exception to this is that the superscript numbers should be placed before dashes.
- When a footnote must be placed at the end of a clause,1 add the number after the comma.
- When a footnote must be placed at the end of a sentence, add the number after the period.2
- Numbers denoting footnotes should always appear after punctuation, with the exception of one piece of punctuation3—the dash.
American Psychological Association (APA)
Like MLA, APA discourages the use of footnotes unless absolutely necessary. Even then, the guide recommends that footnotes only be used to provide content notes (such as providing brief, supplemental information about the text or directing readers to additional information) and to denote copyright permissions. The rules regarding placement of the in-text numbers is the same in APA as in MLA.
Chicago Manual of Style (CMS)
Of the three main style guides described here, CMS relies on footnotes the most. While CMS does allow the author–date system of in-text referencing (i.e., providing the author's name and the date of publication in parentheses at the end of the phrase, clause, or sentence that references the work), it also offers a citation style in which footnotes or endnotes are employed. In both cases, bibliographies are also required. Whether an author should use the author–date system or footnotes is often decided by the author's professor, journal, or publisher.
As an example, if footnotes are used, the following format should be adhered to when referencing a book in CMS:
Technical Guide to Using Footnotes
To use footnotes in your own book, essay, or article, you must first decide on the most appropriate and logical placement of your footnotes in the text. Add numbers according to your chosen style guide, and be sure to add the numbers directly after the phrase, clause, or sentence to which the corresponding footnote refers.
Footnotes can be added quickly and easily using Microsoft Word. Here's how to use footnotes in Microsoft Word 2013:
1. Click on the place in the text where you want the first number to appear.
2. In the References tab, there is a Footnotes group. In that group, click the button that says Insert Footnote.
3. After you click that button, two numbers should appear: one number should appear in the main text, and the corresponding number should appear at the bottom of the page.
4. Write your citation or additional information next to the number that appears in the footer. Format the information according to the rules of your style guide.
Congrats! You've created your first footnote. You can also adjust the footnote settings (like the numbering) by clicking the arrow beside the Footnotes group. It's really that easy!
Final Tips and Tricks
To avoid cluttering the page, you should use footnotes sparingly and only to provide helpful additions or citations. As previously noted, this information may be considered supplementary, which is why it's best to place it away from the main portion of your writing.
When creating your footnotes, always keep reader convenience in mind and remember that the footnotes are there to convey helpful information. If your footnotes are excessive or unnecessary, readers are likely to become annoyed and may even be distracted from the main points of your writing.
Now that you're no longer asking "What are footnotes?" and you know how to use them according to various style guides, footnotes can become a great asset to you as a writer. Be sure to follow the recommendations above, as well as those of your preferred style guide, to ensure that you're using footnotes to their best effect.
