Usage scenarios of footnotes and endnotes: when to use which one

When writing a paper or report, should supplementary explanations and source information be placed in footnotes, endnotes, or a reference list? This article provides judgment methods according to content type, layout and format requirements, and explains the operating steps in the UniDoc editor.

Key points of this article

  • Use footnotes or endnotes for supplementary explanations, and reference lists for source information. The functions of the two are different, so do not mix them.
  • Footnotes are at the bottom of the page, so readers don’t have to turn the page; endnotes are concentrated at the end of the article, making the layout cleaner and suitable for long articles with many notes.
  • The reference format is determined by the citation system: the sequential coding system is numbered according to the first occurrence, and the author-year system is ordered by author.
  • Asking about the annotation rules of the school template or journal before writing will save time than adjusting it afterwards.

When writing a paper, course report or project proposal, you often encounter a sentence that needs to be added: it is not suitable to be included in the text, and the source needs to be explained. At this time, should I use footnotes, endnotes, or put it directly into the reference list? The three positions all look like "information attached to the main text", but they have different functions. If you choose the wrong one, your tutor or reviewer will find problems with the format, and readers will not be able to find the information they need.

This article is written for students, researchers, and report writers who need to format long documents themselves. After reading, you can judge where a piece of information should be placed, know the difference between footnotes and endnotes, and distinguish between footnotes and references. At the end of the article, the general steps for inserting footnotes and endnotes in the UniDoc editor are also given.

Footnotes, endnotes or reference lists, how to choose? One sentence conclusion

First check whether the content is "supplementary explanation" or "source information". Use footnotes or endnotes for supplementary explanations, and source information should be included in the reference list; between footnotes and endnotes, look at the layout and format requirements.

What are the three positions responsible for?

Footnotes: Explanation on the same page, read nearby

Footnote headers appear somewhere in the text, with corresponding notes at the bottom of the same page. It is suitable for explaining terminology, adding background, clarifying the scope of data, or qualifying a point. For example, if the main text reads "This study used a questionnaire survey", the footnote can add "The questionnaire underwent two rounds of revisions during the pre-survey." Readers need this kind of content, but putting it in the main text will interrupt the discussion.

Footnotes can be numbered continuously throughout the article, or they can start again from 1 on each page, depending on the school template or journal requirements. This should be determined first when writing, otherwise it will be troublesome to adjust the numbering later.

Endnotes: centralized placement, suitable for long articles with many comments

Endnotes group all notes at the end of a section, chapter, or entire text. The advantage is that the layout is clean, and the text page is not crowded with comments at the bottom; the disadvantage is that readers need to turn to the back to see the explanation, and the reading is less coherent.

Endnotes are more suitable for documents with a large number of notes and long single paragraphs, such as legal documents, historical research, or reports with a lot of background explanation. If there are only a few notes, using endnotes will cause readers to turn pages frequently, which is not as intuitive as footnotes.

Reference List: Ledger of Sources

The reference list lists all cited documents and is the basis for readers to check sources. Its format is determined by the citation system: sequential numbering by first occurrence, author-year by surname.

Note that the reference list is a list of sources, not an annotation area. It answers "What is the basis for this sentence" rather than "What else does this sentence need to say?"

Common confusion

  • Write complete bibliographic information into footnotes and lists at the same time. The same document is written completely in two places. It is easy to miss one of the parts when revising, resulting in inconsistency. The usual practice is to only write subtitles in the main text, and the complete information only appears once in the list.
  • Tuck explanatory content into the reference list. Only sources should be included in the list, and additional explanations should be placed in footnotes or endnotes.
  • I think endnotes must be more standardized than footnotes. Both are standard annotation forms, which one to choose depends on the school template, journal requirements and the number of annotations.
  • Replace citations with footnotes. Just write "Meet so-and-so report" without including it in the references, so readers cannot trace it back. The source must be included in the list.

# how to use it

In the UniDoc Web Page Editor (app.unidoc.top), or in the UniDoc document editor in the desktop client, footnotes and endnotes can be inserted in a Word-like manner. The following is a common sequence of operations:

  1. Determine the format rules first. Check the school template or journal contribution instructions, make clear whether the notes are footnotes or endnotes, whether the serial number is continuous or rearranged on each page, and whether the references are sequentially coded or author-year system.

two. Insert a footnote or endnote where you need to explain and write only one or two sentences of explanation. If it is the source information, only the corner mark is retained in the text, and the complete literature information is put into the reference list.

  1. Read through the full text after writing, check whether the corner numbers are continuous, whether the footnotes are cut off on the page, and whether each citation number in the text can be found in the reference list.
  2. If you need to give it to someone else in Word format, open the file after export to check the location and number of the comments and make sure it is the same as when editing.
  3. If the manuscript is to be submitted in PDF, check the layout again before export to see if the footnote at the bottom is complete.

# which method is suitable for you?

To write a course report, it mainly needs additional explanation: it is convenient for readers to read with footnotes. -submit contributions to journals or take exams with a unified template: first determine footnotes or endnotes according to the submission requirements, not on your own. -write long documents with a lot of comments: endnotes are preferred to avoid being crowded at the bottom of the page. -Research reports citing a large number of data and literature: the text is kept concise, the source is mainly the list of references, and the notes only contain the necessary explanations.

# frequently asked questions (FAQ)

1. What is the difference between footnotes and endnotes in applicable scenarios?

Footnotes are suitable for short explanations that need to be seen on the page, while endnotes are suitable for situations where there are a large number of comments, a long length, and do not want to occupy the body page. There is no essential difference between the two in content, mainly depends on the layout and reading habits.

2. How do you divide the usage scenarios of footnotes and references?

Footnotes are used to supplement notes, and references are used to list sources. As long as the information is "what is the basis of this sentence", it should be included in the reference list; as long as the information is "what else does this sentence need to explain", you can use footnotes.

3. Can I use both footnotes and endnotes in the same document?

Technically yes, but usually not recommended. A document remains consistent, making it easier for readers to adapt. Only when schools or journals explicitly require separate use, the two need to coexist.

4. What if the numbers are not continuous?

First check to see if the number has been manually modified. If you use automatic numbering, the numbering usually adjusts automatically after you delete or move comments; if you enter numbers manually, you are prone to confusion. After revision, you should read through the full text and check again whether the corner marks correspond to the notes one by one.

5. Can you write only the author's name in the comments?

It depends on the format of the reference. Under the author-year system, the text usually marks the author and year directly, and there is no need to repeat in the notes; under the sequential coding system, the text is marked with corner marks, and the complete information is placed in the reference list. The specific rules are subject to the requirements of the school or periodicals.

# Summary

To judge the use of footnotes and endnotes, the key is to distinguish between supplementary notes and source information: supplementary notes are used with footnotes or endnotes, and source information is included in the reference list. First determine the format rules, and then select the location according to the content, and read the check number before handing in the manuscript, which can avoid most of the rework.
