How to Cite Research Papers? : All Formats & Examples

1. Why is citation important?

When you cite your sources, it means that you are indicating to your audience the source of the information, quotations, or ideas which have been used in your research work.

Below is an explanation of the significance of citation along with examples:

1.1. Citation Helps to Avoid Plagiarism and Shows Respect to Creators

The process of citing will help to protect your writing from the accusation of plagiarism, which is the presentation of someone else's ideas or work as your own. Moreover, when you cite sources, you follow the copyright regulations and properly acknowledge the works done by the authors.

For instance, if you quote an expression in your research work, like "I've a feeling we're not in Kansas anymore", you need to indicate the citation as (Wizard of Oz) near it. Thus, you demonstrate that you are using the line from a certain movie.

1.2. It Establishes Your Authority and Credibility

Whenever you cite properly in your paper, you demonstrate to your teacher or readers that you have actually conducted some research. This means that your arguments and claims are based on evidence and not on your assumptions or ideas.

Example: For instance, when you make an assertion such as "digital photography is more environmentally friendly than traditional photography" in your paper, using an in-text citation such as "(Eco-tography 119)" demonstrates to your readers that a reliable source exists to back up your claim.

1.3. It Allows Readers to Locate the Source of the Reference

Citing allows for giving directions or mapping out the way for the readers. With the help of a citation, the reader knows all the necessary information related to the work—the name of the author, the title of the work, the year of publication, and the page number—to find it himself or herself.

Example: When you mention a statistic such as, "In a survey conducted among 1000 people, 80% felt that it was necessary to have investments in renewable energy," the number will lead the reader to the full reference at the end of your work. Thus, the reader will be able to look up the study through the link given in the reference.

1.4. It Is Indicative of Accountability and Courtesy

Adherence to the standardized citation style is indicative of your professionalism, responsibility, and courtesy to your readers. You will demonstrate your accountability by being clear about which part of your work belongs to your original ideas and which parts are taken from other sources.

2. How to cite a research paper in different formats?

The citation style used by you determines the way of organizing information about the author of the research paper (published as an article), its title, the title of the journal in which the article is published, the date of publishing, and page numbers.

Here is a summary of the process of citation of the research paper according to different styles of writing.

2.1. APA Style (7th Edition)

Used commonly in the fields of social sciences, psychology, and education. Uses an “author-date” approach.

In-text citation:

(Author Last Name, Year)

Example: (Turner, 2007)

References list:

Author Last Name, Initials. (Year). Article Title. Journal Name, Volume(Issue), Pages. DOI/URL

Example: Turner, J. H. (2007). Justice and emotions. Social Justice Research, 20(3), 288-311. https://doi.org/10.1007/s11211-007-0043-y.

2.2. MLA Style (9th Edition)

Commonly used in the humanities, literature and languages. Uses the “author-page” format.

In-text citation:

(Author’s Last Name Page Number).

For example: (Newmeyer 682).

Works Cited Entry:

Author’s Last Name, First Name. "Article Title." Journal Name, vol. #, no. #, Year, pp. Page number(s). Database name, DOI/URL.

For example: Newmeyer, Frederick J. "Grammar is Grammar and Usage is Usage." Language, vol. 79, no. 4, 2003, pp. 682-707. JSTOR, www.jstor.org/stable/4489522.

2.3. Chicago Style (Notes and Bibliography)

Commonly used in history, fine arts, and certain areas of humanities. Uses superscript numbers in text referring to endnotes placed at the bottom of the same page.

In-text citation:

¹ Last Name, First Name, “Article Title,” Journal Name, volume, no. issue (year): page number cited, DOI/URL.

Example: ¹ Hyeyoung Kwon, “Inclusion Work: Children of Immigrants Claiming Membership in Everyday Life,” American Journal of Sociology, 127, no. 6 (2022): 1842, https://doi.org/10.1086/720277.

Bibliographic entry:

Last Name, First Name. “Article Title.” Journal Name, volume, no. issue (year): page range. DOI/URL.

Example: Kwon, Hyeyoung. “Inclusion Work: Children of Immigrants Claiming Membership in Everyday Life.” American Journal of Sociology, 127, no. 6 (2022): 1818–59. https://doi.org/10.1086/720277.

2.4. IEEE Format

Used for engineering, computer science, and technical subjects. A numbered referencing style is used.

In-text citation:

A number in square brackets.

For example: [1]

Reference List citation:

[#] A. Initials. Last name, “Article Title,” Journal Abbreviation, volume number x, issue number x, pages xxx-xxx, Month Year.

Example: J. Smith, “The Future of AI,” IEEE J. Artificial Intell., vol. 2, no. 4, pp. 123-135, Dec. 2022.

2.5. AMA Style (11th Edition)

The standard format for clinical medicine and the health sciences. It utilizes superscript numerals in the body of the paper, similar to the Chicago style, but without footnotes; rather, the numerals refer to a list of references in numerical order.

In-text citation:

Superscript numeral that is placed outside commas and periods.

For example: There was a significant decrease in injuries.¹

Reference List format:

Author’s Last Name Initials (no periods). Title of article. Title of Journal abbreviated. Year;Volume(Issue):Page numbers. doi:

For example: 1. Kassim R, Osei E, Cronin KA. A review of the effects of tobacco smoking on cancer treatment: smoking cessation intervention should be integrated into the cancer care continuum. J Radiother Pract. 2020;19(1):84-92. doi:10.1017/S14603969000360.

2.6. Harvard Referencing System

Commonly used around the world in economics, business, and other sciences. It is similar to APA in that it is an author-date referencing system, though there are some minor differences in formatting.

In-text citation:

(Author Surname, year)

Example: (Adamson, 2019)

References List:

Author Surname, Initial(s). (year) ‘Title of article’ Journal Name, Volume(Issue number), pp.Page number range. Retrieved from: URL/DOI

Example: Adamson, P. (2019) 'American history at the foreign office: Exporting the silent epic Western' Film History, 31(2), pp. 32-59. doi: https://10.2979/filmhistory.31.2.02.

3. How to cite different kinds of sources in a research paper?

Citing different kinds of sources in a research paper means that different types of information will be provided depending on the medium of your source (i.e., a printed book or an online video). However, even though the exact punctuation and order may vary according to the style used (APA, MLA, Chicago, etc.), certain elements called core elements will always be needed to cite each specific kind of source.

This is an example of the process and how to cite different kinds of sources depending on their medium:

3.1.Books

The core elements you need to look for when citing a book are the name of its author, the title of the book itself, the name of the publishing company and the date of publication.

MLA Style Example: Bennett, Britt. The Vanishing Half. Riverhead Books, 2020.

Harvard Style Example: Smith, Z. (2017) Swing time. London: Penguin.

3.2. Journal Articles

In citing journals, these are seen as small parts in a big "container," i.e., the journal. The information needed here includes the author’s name, article title, name of the journal, volume and number, year, and page numbers and DOI/URL if obtained through online media.

APA Example: Turner, J. H. (2007). Justice and emotions. Social Justice Research, 20(3), 288-311. https://doi.org/10.1007/s11211-007-0043-y

IEEE Example: J. Smith, “The Future of AI,” IEEE J. Artificial Intell. vol. 2, no. 4, pp. 123-135, Dec. 2022.

3.3. Websites

Since websites do not contain traditional publication pages, here you will need to find the name of the author/organization, title of the webpage/article, name of the entire website, its publishing date and URL.

Chicago Example: Google. “Privacy Policy.” Privacy & Terms. Effective November 15, 2023. https://policies.google.com/privacy.

AMA Example: American Physical Therapy Association. Ethics & professionalism. Updated June 5, 2019. Accessed February 12, 2020. http://www.apta.org/EthicsProfessionalism/

3.4. Online Videos (e.g., YouTube)

When using multimedia content, you have to acknowledge its creator. Normally, you will need the author or uploader’s name, the title of the video, the website where it was uploaded, and the URL.

MLA Style Example: “What’s New in the MLA 9th Edition Handbook.” YouTube, uploaded by Xamplio, 5 Oct. 2021, https://www.youtube.com/watch?v=OflVWUwRRlI.

4. Top 8 Tips for citing a research paper

4.1. Document your sources as you proceed

Never leave your reference list compilation until after you have completed writing your paper. Each time you make use of a source, take immediate notes of all the important information you would be needing such as the author, the title of the work, where the work was published, the year of publication and page numbers. Attempting to document these later would be very difficult and error-prone.

4.2. Paraphrase correctly, but cite anyway

Paraphrasing someone else's work does not exempt you from providing a citation. If the original idea was taken from another work, it is your responsibility to provide the author credit to avoid plagiarism. Also, be sure that you have paraphrased the sentence by restructuring it completely; otherwise, if it is almost the same as the original work, it is an example of bad paraphrasing.

4.3. Use quotes when using direct quotes

If you quote any of the words that belong to another author, you have to place those words between quotes, including an in-text citation. You should use the exact wording you have found in the text, preserving its punctuation, spelling, and capitalization. Not citing words within quotes is probably the most frequent mistake made by students.

4.4. Double-check citation generated by automated citation generators

Tools such as Zotero, Mendeley, MyBib, and Citation Machine are excellent helpers that allow you to organize your sources and generate citation automatically, but these software products cannot be trusted because sometimes they make mistakes. Make sure the generated citation corresponds to the rules in your style guide.

4.5. Assess your sources

If you cite a source, this source has to be of good quality. You should always use the CRAAP test to assess the quality of each source: it has to be Current, Relevant, Authoritative, Accurate, and Purposive (educational in nature, not commercial or political).

4.6. Follow your instructor's individual guidelines

Most universities and even departments develop and offer their versions of citation styles. The individual guide of your school and the instructions in your syllabus should be your guide above all others. When you find yourself in the situation when you need to choose between conflicting citation styles or want to get more precise formatting instructions, just ask your instructor.

4.7. Make sure your citation information is absolutely correct

Check all information in your references list, including spelling of the names of authors and titles. Any mistakes, including those that happened unintentionally, in your citation list will lead to incorrect citation, which might accidentally become plagiarism.

4.8. Check your paper for proper citation balance

Although citation software can greatly simplify formatting process for you, it will not be able to check whether your citations correspond to the context of your work. Carefully check your text in order to make sure that all of your facts are supported by sources, but there are no so many quotations that you ideas become invisible.

5.Conclusion

In short, whenever you are writing a paper and using information from the internet, a book or an article, referencing does the following four things:

• It says 'Thank you': It gives credit to the original authors for all the effort they have made.

• It makes you responsible: It helps you differentiate your own thoughts from those you got from other people. This shows that you are not plagiarizing anyone's work.

• It gives directions to your readers: It provides your readers with all the directions (author's name, title and a link) to the original information that you used.

• It proves your honesty: It proves to your instructor or the audience that you conducted your own research, and the facts provided by you are well-supported.

To sum it up, regardless of whatever style of referencing is required from you (APA, MLA or Chicago), the core purpose is the same.
