What Is “Et Al.” and How to Use It?

Perhaps bibliography writing is one of the least pleasant parts of paper writing. However, given that it is an integral part of any academic writing, students must always deal with it. Being a pro researcher or writer, the ‘et al’ application while complying with the reference list may not be a significant concern. However, most learners rarely involved in writing academic papers may feel confused and anxious about unknown abbreviations that are unlikely to meet in everyday speech.

Especially for this category of students, we share detailed guidelines with critical aspects and peculiarities.

Know What Does Et Al. Mean?

You must know its interpretation and origin to use the discussed abbreviation properly. So, what does et al mean? The Latin term ‘et alia’ is translated as ‘in addition’ and is typical for bibliography and citations. However, you must be careful with the requirements of referencing styles when enlisting several authors. It simplifies writing and eliminates long references since you do not have to mention all the writers whenever you mention the source.

Cases When to Use Et Al.

As a rule, it is used when you refer to words or scientific papers in your text and have to indicate the author. Nothing is challenging to write one last name in the parenthesis. However, what if there are three or more co-authors? Of course, you may know or quickly find all the names, but there is no need to enlist all if it is an in-text citation or bibliography. Note et al is relevant for cases when at least three authors are mentioned in a raw.

When to Use Et Al.: General Principles

Now, you know when to use et al, so it is high time to define how to use it. Note that since it is an abbreviation, you should never forget about a period at the end (et al.) You should also mention the author’s last name and year of publication. There are several tips for you to follow if you need to know whether you need this abbreviation.

  • Define the number of authors. If there are three or more authors, you can use “et al” to refer to all the authors after mentioning the first one.
  • Introducing the authors. If there are three to five authors, you should list all of them in your first in-text citation.

e.g., Smith, Herbert, James, and Catherine (2009).

However, use abbreviated names and et al in all the following citations.

e.g., Smith et al. (2009)

  • Remember to include the full list in the bibliography. Provide the complete list of author’s names in the reference list or bibliography.

Pay attention that it is essential not only to know how to use et al but also consult the specific formatting style guide of the latest edition or requirements provided by your institution or publisher, as they may have variations or specific rules for using “et al” in citations.

Et Al. Citation Use

The et al citation in the text adheres to the above-mentioned rules. You must mention only the first author in the second, third, and all subsequent in-text citations. But what if you refer to the author who has issued several books in collaboration with others?

Let’s explore such cases in the examples. Suppose you refer to two different sources, and there are one or more similar co-authors:

e.g., Book by John Smith, Raynold Lee, Austine Anderson, and Tom Sheldon (2019)

e.g., Book by John Smith, Raynold Lee, Mary Anders, Kripke James, and Joyce Herbert (2019)

It will be incorrect to refer to both sources, mentioning only the first author, which may confuse your reader. In such a situation, you should act according to the particular standards. Cite the first source as:

  • Smith, Lee, Anderson, and Sheldon (2019)

Refer to the second publication using Latin abbreviations.

  • Smith, Lee, Anders, et al. (2019)

In the last sample, et al stands for two authors. Replacing one last name with a given abbreviation is impossible in the first sample.

Et Al. Citation APA Style

In APA style, the et al abbreviation indicates several authors for a source when citing within the text and in the reference list. Here are the rules for using the et al citation APA style:

  • In-text citations: When citing a source with multiple authors for the first time, list all the authors’ names in your in-text citation. For subsequent citations of the same reference, use the initial author’s last name followed by “et al”

e.g., First citation: (Smith, Johnson, Anderson, et al., 2020)

e.g., Subsequent citations: (Smith et al., 2020)

  • According to the last (7th) edition of APA formatting, if you deal with a reference list, include the names of all authors for sources with up to 20 authors. For sources with 20 or more authors, list the first 19 authors’ names, add an ellipsis (…) and the last author’s name.

e.g., 20 authors or more: Smith, J., Lee, A., Anderson, B., … Taylor, L. (2020).

Remember to follow and refer to the official APA Style Manual or the APA website for more specific guidelines and samples.

Et Al. Citation MLA Style

If in the instructions for your paper, you are to adhere to MLA, another formatting style, you must be aware of et al citation MLA requirements. Like in any other case, et al indicates the multiple authors of selected sources.

  • In-text citations of sources with multiple authors for the first time, list all the authors’ names. For subsequent citations of the same source, use the first author’s last name followed by “et al”

e.g., First citation: (Smith, Johnson, Anderson, et al. 45)

e.g., Subsequent citations: (Smith et al. 45)

  • In the bibliography, include the names of all authors for sources with up to three authors. For sources with four or more authors, list the first author’s last name followed by “et al”

e.g., Up to three authors: Smith, John, Title of Work. Publisher, 2020.

e.g., Four or more authors: Smith, John, et al. Title of Work. Publisher, 2020.

Be careful with the year of publication in in-text citations since you do not indicate the whole number, only the last two digits. Of course, if there are hesitations, you may consult an MLA style guide of the latest edition.

Et Al. Citation Chicago Style

If you face Chicago reference style in your writing, you should consider some differences between APA and MLA mentioned above. Of course, if there are over three authors, you must refer to et al citation Chicago rules. However, this style requires footnotes in citations.

  • The in-text citation requires the last name of the initial author, plus et al, year of publication, and referred pages.

e.g., First citation: (Smith et al., 2019, 21-22)

e.g., Subsequent citations: (Smith et al., Pi, 30-33)

  • In a bibliography, you should organize the used reference in the following way:

e.g., Smith, John. et al., Pi. 2019

In Chicago style, “et al” is used only in the in-text citations and not in the bibliography entry itself. The names of all authors must be listed in the bibliography.

Harvard Citation Et Al. Rules

As previously mentioned, styles et al in Harvard style stands for 3+ authors in the reference. But let’s have a look at the Harvard citation et al application.

  • In-text citation rules are similar to those above and differ in whether you cite for the first time or subsequently.

e.g., First citation: (Smith, John, Anderson, et al., 2019)

e.g., Subsequent citations: (Smith et al., 2019)

  • In the reference list, you must include the names of all authors for sources with up to three authors. For sources with four or more authors, list the first author’s last name followed by “et al”

e.g., Up to three authors: Smith, J., Johnson, A., Anderson, B., … Taylor, L. (2019).

e.g., Four or more authors: Smith, J., Johnson, A., Anderson, B., … Taylor, L., et al. (2020).

There is also a Harvard-style manual that you may consult to avoid mistakes and have more examples.
