How to Write References and Cite Sources in a Research Paper
Table of contents
Citation is necessary while writing your school essay, a publication, or a Master’s thesis. We all want our efforts to be acknowledged, right? The lack of references and citations can make the source think you are trying to steal their work. Hence, the question is how to go about making references.
Do you want to learn how to cite in a research paper? Then this article is for you, as it contains the details of how to reference when writing a research paper. There is a standard way to do this in educational journals and organizational publications.
Hence, a researcher must understand how to reference their writings or journals. It is another thing to write a journal properly, but crediting the sources is more crucial.
Follow this guide to learn:
- The importance of referencing and citations for your academic works;
- How to cite in APA, MLA, Chicago, IEEE, and ASA styles;
- Essential guidelines to follow for a published work.
Why Referencing and Citation Matter
Another important question is: What is the need for referencing and citation? The major reason for citations in research paper format is to serve as directional cues for the employed knowledge. When you cite, readers can know that some portions of your content belong to you. Hence, it is easier to identify how recent the information is.
Citation for your paper comes with several advantages. They include:
Academic Integrity
The citation affirms the integrity of your academic writing. In this information age, there are several details, and it can be difficult to authenticate. When you reference, it helps readers understand the necessity of the discussed topic. Referencing certain authors can give more authority to your papers.
Avoiding Plagiarism
Plagiarism refers to the mindless lifting of details from another material without acknowledging the details. For the source, they could believe you are stealing from them. In most countries, copyright infringement is a punishable crime and can make you lose your hard work.
Building Credibility
Credibility is the goal of every academic scholar. There is no better way to gain relevance than by citing sources from other credible ones.
Facilitating Further Research
For other researchers like you, providing citations can serve as other sources for more information. It helps them to know other philosophies about the subject.
Choosing the Right Citation Style
Now that the advantages have been established, the new worry is the choice of the right style. There are several styles with their respective peculiarities. For example, the MLA writing style is common in liberal scientific paper citations. Let’s delve more into MLA formatting for research papers and other styles.
APA (American Psychological Association)
The commonest style used by many scholars is APA formatting, especially if there is no stated style. This approach employs the use of in-text citations to explain the source. It’s the simplest form of citation.
Here is an in-text referencing example:
“Exercise is a good way to recover from ailments.” APA, n.d. (American Psychological Association).
The reference style includes:
- The author’s name;
- The author’s name is in parenthesis to follow the referenced excerpt;
- The publication date.
MLA (Modern Language Association)
MLA-style formation is concise and known for its scientific referencing format. The peculiarity of the MLA citation is its source citation, episode title, and document layout. You have to:
- Include the parenthetical citation;
- Create some spaces away from the left margin;
- Include the author’s or source’s name.
Ensure you capitalize every word when including the names. You can employ professional MLA Citation Generators to make the compilation easier. It is perfect for the citation format of scientific papers.
Chicago Style
Chicago’s style is famous for two things:
- The in-text citation within the paper;
- The reference list is at its end.
It is an author-date approach. Hence, the in-text citation for a research paper has the author’s or source name and publication year.
IEEE (Institute of Electrical and Electronics Engineers)
This employs the use of numbers. It is chronological as it arranges the citation based on the order of appearance. A click on it takes the reader to the full reference at the end of the paper. To make it easier, you can employ IEEE Citation Maker for a well-curated task. This way, you won’t have to worry about the manual compilation of the IEEE citation style.
ASA
This is similar to the author-date approach by Chicago Style. You can:
- Create the quotation;
- Include the parentheses for the author’s name and publication date;
- Add the page number using a colon.
Components of a Citation

Author(s)
The author is also regarded as the source. It is the original writer of the material you are referencing. Sometimes, there may be multiple authors. Do not miss out on anyone while citing a research paper.
Title of the Source
The title of the source is often the name given to the material by the author.
Publication Date
As the name implies, this refers to the date the source was published. Frequently, most writers include it at the start of their material. State the exact month and year of publication, separated with a comma. See example:
“(2016, March 7).”
Publisher
Including the publisher’s details is only necessary for the full reference. It should be at the end of the paper. It can facilitate further research.
Page Numbers
The page number is necessary, as it helps to easily refer to different sections of the paper.
DOI (Digital Object Identifier) or URL (Uniform Resource Locator)
A DOI is a link to a resource on the internet. The resource can be a book or its chapter. On the other hand, a URL is an address that indicates where the resource can be found. It helps to locate the resource. The use of URLs and DOIs directs readers to the digital identifier of the source.
In-Text Citations
An in-text citation for a research paper is the brief form of the bibliography that you include in the body of the content. It contains the author’s family name and year of publication. It provides enough details to help users know the source in their reference list. Each citation format for research papers is unique.
See citation examples below.
How to Cite Direct Quotations for Each Citation Style
The general rule in referencing is that in-text citations must have a corresponding entry in your reference list. Let’s see how!
APA
There are two types of APA in-text citations:
Parenthetical:
The researchers concluded, “Climate change poses significant challenges for coastal communities” (Johnson & Lee, 2021, p. 78).
Narrative:
In their study on the effects of exercise on mental health, Smith and Johnson (2019) found that regular physical activity was associated with a significant decrease in symptoms of anxiety and depression. According to their research, engaging in exercise three times a week for at least 30 minutes had a positive impact on participants’ overall well-being.
APA in-text citation style employs the source’s name and publication year. A direct quotation will include the page number. Remember, you can generate a citation in a research paper using the APA style via a citation generator.
MLA
MLA is known as the scientific style of citation. The uniqueness of MLA Style formatting is the use of a direct quote (in quotes), the Author’s name and page number (in parentheses).
Example:
In the novel “To Kill a Mockingbird,” Atticus Finch imparts wisdom to his children, saying, “You never really understand a person until you consider things from his point of view… until you climb into his skin and walk around in it” (Lee 30).
Chicago
For Chicago, you are to include a parenthetical citation, the author’s name, the publication year, and the quote’s page number.
Example:
As Adams (2009) argues, “History is a vast early warning system” (53).
IEEE
IEEE (Institute of Electrical and Electronics Engineers) style typically uses numerical citations in square brackets for in-text citations. It doesn’t rely heavily on direct quotations in the same way as some other citation styles, like APA or MLA. Instead, IEEE generally prefers paraphrasing and citing the source, but direct quotations can be used when necessary. Here’s an example of a direct quotation in IEEE style:
In-Text Citation:
As stated by Smith, “In most cases, the impedance of the transmission line remains relatively constant throughout its length” [1].
Corresponding Reference Entry:
[1] A. Smith, “Transmission Line Impedance Analysis,” IEEE Transactions on Electrical Engineering, vol. 45, no. 3, pp. 212-225, 2010.
ASA
ASA is different because it contains the author’s name, publication year, and even the page number.
According to Smith (2010), “Social institutions shape our behaviors and interactions in profound ways” (p. 45).
How to Cite Paraphrased Information
While writing a college paper, paraphrasing is important to achieve clarity, but it is ideal to cite the source of the paraphrased information. The proper way to cite paraphrased information is to include a parenthetical citation. The style of referencing for all citation styles doesn’t change, but they should be in parenthesis.
Example:
“Strength can be defined in terms of ability and acquired skills, according to (Jack et al. 2023).
Citing Multiple Authors
The technique is different when you are citing a source that has multiple authors. For the first-time citation, you should include the names of all the authors. The subsequent activities to generate a citation in APA should only include the first author’s surname and the proper use of ‘et al.’ However, you should include the surname and initials of all these authors in the full reference. Separate the authors with commas and ampersands before the final name.
Example:
APA
Two Authors:
When a source has two authors, include both authors’ names in the in-text citation every time you reference the source. Use an ampersand (&) between the authors’ names, and include the year of publication in parentheses. For example:
(Smith & Johnson, 2020) found that…
Three to Five Authors:
When a source has three to five authors, list all authors in the first in-text citation. Use an ampersand (&) between the last two authors’ names. For subsequent citations of the same source, use only the first author’s name followed by “et al.” and the year. For example:
First citation: (Smith, Johnson, & Williams, 2018)…
Subsequent citations: (Smith et al., 2018)…
Six or More Authors:
When a source has six or more authors, you should use “et al.” in both the first and subsequent in-text citations, along with the year. For example:
(Smith et al., 2019) conducted a study on…
Group Authors:
When citing sources authored by a group, organization, or company, use the full name of the group or organization as the author in the in-text citation. If the abbreviation is well-known, you can use the abbreviation in subsequent citations. For example:
First citation: (American Psychological Association [APA], 2019)…
Subsequent citations: (APA, 2019)
MLA
Two Authors:
When a source has two authors, include both authors’ names in the in-text citation, separated by the word “and.” For example:
(Smith and Johnson 45) found that…
Three or More Authors:
When a source has three or more authors, include only the first author’s name followed by “et al.” in the in-text citation. For example:
(Smith et al. 72) conducted a study on…
No Author:
If a source has no identifiable author, use a shortened version of the title in the in-text citation. Enclose the title in double quotation marks or use italics if it’s a longer work (e.g., a book or film). For example:
(“Title of the Source” 28) argues that…
Group Authors:
When citing sources authored by a group, organization, or company, use the full name of the group or organization as the author in the in-text citation. If the abbreviation is well-known, you can use the abbreviation in subsequent citations. For example:
(American Psychological Association 62) states that…
Chicago
Author-Date System:
Two Authors:
In the Author-Date system, when a source has two authors, include both authors’ last names and the publication year in parentheses in the in-text citation, separated by an ampersand (&). For example:
(Smith & Johnson 2020) found that…
Three or More Authors:
When a source has three or more authors, you can use “et al.” after the first author’s name in the in-text citation. For example:
(Smith et al. 2018) conducted a study on…
Notes and Bibliography System:
Two Authors:
In the Notes and Bibliography system, when a source has two authors, include both authors’ full names in the note. For example:
John Smith and Jane Johnson, Title of the Work (Place of Publication: Publisher, Year), page number.
Three or More Authors:
When a source has three or more authors, list the first author’s name followed by “et al.” in the note. For example:
John Smith et al., Title of the Work (Place of Publication: Publisher, Year), page number.
ASA
Two Authors:
When a source has two authors, include both authors’ last names in the in-text citation, separated by the word “and.” For example:
(Smith and Johnson 2020) found that…
Three Authors:
When a source has three authors, include all three authors’ last names in the in-text citation, separated by commas. For example:
(Smith, Johnson, and Williams 2018) conducted a study on…
More than Three Authors:
When a source has more than three authors, you should use the first author’s last name followed by “et al.” in the in-text citation. For example:
(Smith et al. 2019) conducted a study on…
IEEE
Two Authors:
When a source has two authors, include both authors’ last names in the in-text citation, separated by “and.” For example:
[1] Smith and Johnson found that…
Three or More Authors:
When a source has three or more authors, use the first author’s last name followed by “et al.” in the in-text citation. For example:
[2] Smith et al. conducted a study on…
Page Numbers in In-Text Citations
The use of page numbers in in-text citations is more peculiar to APA style. You can use paragraphs as indicated above if the source has no page, as seen in some e-books and websites.
Creating a Reference List or Bibliography
Creating a reference list is one of the most important tips for writing a research paper because it shows the general scheme of paper citation. This part of the content is a step-by-step process you can follow to create your reference list for your research paper.
Formatting and Organizing Your References
Formatting and organizing your references is the first step when you want to create your bibliography. You need to arrange all the full references to the in-text citation in the downward part of your paper. To avoid missing out on any, writing every full reference when you write the in-text citation is advisable.
Alphabetizing Your References
Alphabetizing your references ensures you create your bibliography in an orderly fashion for easy comprehension. Hence, you can do it numerically or alphabetically. The numerical order is dependent on the referencing system you are using, while the alphabetical order uses the author’s name to organize the reference.
Citations for Different Source Types
Different source types have their respective references, even for scientific papers. The commonest sources include books, journals, chapters, presentations, and online (to cite a website).
See how to cite an example for each source below:

Tips for Accuracy
The goal of citing your paper is because of the advantages stated above. As such, you should not negotiate the accuracy of your citation. Here are the tips you can follow for accurate referencing:
Verify Your Source
Confirm if your source is credible or not. It is easier to verify books, journal articles, and chapters. You should check multiple links to confirm their authenticity.
Follow the One Style Guide
Maintain a single referencing style throughout your paper. It is improper to employ multiple referencing styles. If not specified, you can consider the APA style.
Verify DOI and URLs
DOI and URLs can be tricky and sensitive. A simple error with the punctuation can make them invalid. Hence, verifying every DOI and URL with a click is advisable. Discrediting your citation format for a scientific research paper reference based on an invalid URL is not worth it.
Online Citation Generators
Thanks to the digital age, you don’t have to worry about manually compiling your reference or generating its in-text citation. You can employ online generators to do the rough work for you. In turn, you will have more time to focus on the major content of your research work.
Use University Libraries and Writing Centers
Libraries and writing centers have extensive collections of cited sources. Since books, publications, and journals are more credible sources, university libraries remain a valid source to increase the credibility of your paper.
Leave No Stone Unturned!
Referencing and citation are the best way to preserve the relevance of your academic paper. It gives it the appropriate credibility for future use. That means another writer can refer to your work over many years, even when the level of advancement may be unmatched. A well-referenced work is evergreen.
One must note that well-oriented research paper citations have a proper format. The options include APA, MLA (citation style for science), Chicago, IEEE, and ASA. If not stated, it is advisable to follow the APA formatting style, as it is the most common. However, stick with formatting while compiling cited sources for a research paper.
