You’ve spent weeks or even months researching, analyzing data, and refining your ideas for the perfect research paper. But then comes the tricky part—how do you properly credit the sources that shaped your work?

Without proper citations, your hard work could be seen as plagiarized. Citations are essential for giving credit to others and making your argument stronger.

In this blog, we’ll show you how to cite your research paper the right way, helping you avoid mistakes and ensuring your work is done with academic integrity. 

Let’s get started!

how to find sources for a research paper

On this Page

What are Citations? Why Are They Important? 

Citations are references to sources you’ve used while writing a research paper. They show where your information, ideas, or quotes come from, giving credit to the original authors. 

Citations aren’t just a formality; they help you avoid plagiarism and add credibility to your work by backing up your ideas with trusted sources. When you cite correctly, your research paper becomes stronger and more reliable, showing that you’ve built your work on a solid foundation.

Basic Elements of Citations

When writing a research paper, it’s essential to include certain core details to make each citation complete and accurate. Here are the basic elements you’ll typically need:

  • Author(s): Name of the person(s) who wrote the source.
  • Title: Title of the article, book, or source used.
  • Source or Venue: Journal name, book title, or conference where the work appeared.
  • Editor(s): Name(s) of editor(s), if applicable.
  • Volume and Edition: For journals or books with multiple versions.
  • Publication Date: The year or full date when it was published.
  • Page Numbers: Relevant page range for the source.
  • Location: City and country of the publisher (mostly for books).
  • Publisher or University: Institution or publisher name for books or theses.
  • URL: Link to the online source.
  • DOI: A unique digital identifier for scholarly sources.
  • Retrieval Date: Date accessed, especially for sources that may change over time.

These elements help ensure your citations are clear and verifiable for anyone reading your work.

How to Cite a Research Paper in Easy Steps

Citing a research paper correctly can feel overwhelming at first, but breaking it down into steps makes it manageable. 

Let’s walk through each part of the process to help you create clear and accurate citations.

Step 1. Identify the Citation Style Required

The first step in citing a research paper is determining which citation style you need to use. Different fields typically require different styles: APA for social sciences, MLA for humanities, Chicago for history, and so on. 

Check with your instructor or the assignment guidelines if you’re unsure. Once you know the required citation style, it’s time to learn the basic rules that apply to your work.

Step 2. Gather Essential Source Information

Collecting all relevant information is crucial for creating a complete citation. For each source, make sure you have details like the author’s name, title, publication date, journal or book name, publisher, volume, page numbers, and URL or DOI for online sources.

With this information on hand, you’re ready to start creating each citation according to your chosen style.

Step 3. Format In-Text Citations

In-text citations help readers immediately identify which sources support specific points in your paper. For instance:

  • APA: Author’s last name and publication year in parentheses (e.g., Sara, 2021).
  • MLA: Author’s last name and page number without a comma (e.g., Sara 23).
  • Chicago: Superscript number leading to a footnote or endnote.

After adding your in-text citations, the next step is to format each source in the reference list.

Step 4. Create a Reference List or Works Cited Page

At the end of your paper, you’ll need a complete list of references. The format depends on the citation style:

  • APA: “References” list with sources in alphabetical order.
  • MLA: “Works Cited” page, also alphabetical by author’s last name.
  • Chicago: “Bibliography” with full source details.

With your reference list organized, you can move on to handling special types of sources.

Step 5. Adjust for Special Cases (e.g., Multiple Authors, Online Sources)

Some sources require special formatting. For example:

  • Multiple Authors: Different citation styles handle two or more authors differently. APA uses “&” for two authors (e.g., Smith & Jones), while MLA lists both full names.
  • Online Sources: Include the full URL or DOI. Add a retrieval date for dynamic online content that may change over time.

After adjusting for special cases, you’re almost done with your citation work.

Step 6. Use Citation Tools for Accuracy

Automatic citation generators, like Zotero or EasyBib, can save time and help ensure accuracy. However, always double-check the generated citations, as these tools may have formatting errors.

With citation tools checked and adjusted, you’re ready for the final review.

Step 7. Review for Consistency and Completeness 

Before submitting your paper, review your citations carefully. Ensure all in-text citations match the reference list, double-check for consistent formatting, and confirm that each citation is complete and correct.

These were the general steps for citing sources; now, let’s explore how to cite a research paper in different citation styles.

Citing a Research Paper in Different Citation Styles

Different fields use specific citation styles to ensure consistency and clarity. Here are guidelines for citing a research paper in the most commonly used citation styles: APA, MLA, Chicago, IEEE, and Harvard. 

APA (American Psychological Association)

When citing a research paper in APA format, follow the guidelines that prioritize clarity and proper referencing. Below are specific instructions for how to format citations in-text and in the reference list in APA 7th edition.

Used in: Social sciences, psychology, and education

  • Format for In-Text Citation:
    (Author’s Last Name, Year, Page Number)
    Example:
    (Rahman, 2020, p. 15)
  • Format for Reference List:
    Author’s Last Name, First Initial(s). (Year). Title of the article. Journal Name, Volume(Issue), Page Range. DOI

Example:
Rahman, A., & Chen, L. (2020). The impact of social media on cultural diversity. Journal of Global Studies, 10(3), 14-26. https://doi.org/10.1234/jgs.2020.003

Additional Notes:

  • Include a DOI for online sources whenever possible.
  • Use “&” between two authors, and for more than two authors, list the first author followed by “et al.”

APA style prioritizes the year in citations, which makes it easy to reference recent studies.

MLA (Modern Language Association)

MLA style is often used in humanities fields, such as literature and philosophy. The key to MLA citations is to provide enough information for the reader to easily locate the source and the specific part of the work being referenced.

  • Format for In-Text Citation:
    (Author’s Last Name Page Number)
    Example:
    (Chen 38)
  • Format for Works Cited:
    Author’s Last Name, First Name. “Title of the Article.” Journal Name, vol. Volume, no. Issue, Year, pp. Page Range.

Example:
Chen, Li, and María González. “Cultural Representation in Digital Media.” Journal of Media Studies, vol. 12, no. 2, 2021, pp. 33-49.

Additional Notes:

  • MLA omits the DOI in the Works Cited entry but includes the page range.
  • If citing a source with three or more authors, list only the first author’s name followed by “et al.”

MLA style emphasizes page numbers to help locate specific ideas, especially in literature and humanities research.

Chicago Style

Chicago style is known for its flexibility, offering two main citation systems: Notes and Bibliography (NB) and Author-Date. Each serves different academic needs, with the NB system preferred for history and humanities, while the Author-Date system is more common in the sciences and social sciences.

Used in: History, fine arts, and some humanities

Notes and Bibliography (NB)

  • Format for Footnote:
    Author’s First and Last Name, “Title of the Article,” Journal Name Volume, no. Issue (Year): Page Number(s), DOI or URL.

Example:

  1. Li Wei and Ahmed Salah, “Urban Development and Historical Preservation,” International Journal of Urban Studies 15, no. 4 (2019): 87-102, https://doi.org/10.4567/ijus.2019.004.
  • Format for Bibliography:
    Author’s Last Name, First Name. “Title of the Article.” Journal Name Volume, no. Issue (Year): Page Range. DOI or URL.

Example:
Wei, Li, and Ahmed Salah. “Urban Development and Historical Preservation.” International Journal of Urban Studies 15, no. 4 (2019): 87-102. https://doi.org/10.4567/ijus.2019.004.

  • Author-Date Format

In-Text Citation:
(Author’s Last Name Year, Page Number)

Example:
(Wei and Salah 2019, 87)

  • Reference List:
    Author’s Last Name, First Name. Year. “Title of the Article.” Journal Name Volume(Issue): Page Range. DOI or URL.

Example:
Wei, Li, and Ahmed Salah. 2019. “Urban Development and Historical Preservation.” International Journal of Urban Studies 15(4): 87-102. https://doi.org/10.4567/ijus.2019.004.


IEEE (Institute of Electrical and Electronics Engineers)

The IEEE citation style is widely adopted in technical and engineering disciplines, streamlining citation through numbered references that correspond to entries in a reference list.

Used in: Engineering, computer science, and technical fields

  • Format for In-Text Citation:
    [Reference Number]
    Example:
    [1]
  • Format for Reference List:
    [Reference Number] Author’s Initial(s). Last Name, “Title of the Article,” Journal Name, vol. Volume, no. Issue, pp. Page Range, Month Year. DOI

Example:
[1] S. Kumar and F. Y. Lee, “Advancements in Renewable Energy Storage,” Journal of Clean Energy, vol. 9, no. 2, pp. 54-67, March 2022. https://doi.org/10.7890/jce.2022.002


Additional Notes:

  • In IEEE, in-text citations use numbers in square brackets, corresponding to the reference list.
  • List sources in the order they appear in the text, not alphabetically.
  • IEEE style uses numbered references, which keeps in-text citations brief and efficient for technical papers.

Harvard Style

The Harvard citation style is straightforward and commonly used across many academic disciplines, particularly for scientific and social research. It emphasizes author-date in-text citations, which keep sources easy to trace.

Used in: General academic and scientific writing, often in the UK and Australia

  • Format for In-Text Citation:
    (Author’s Last Name, Year)
    Example:
    (González, 2021)
  • Format for Reference List:
    Author’s Last Name, First Initial(s). (Year) ‘Title of the Article’, Journal Name, Volume(Issue), Page Range. DOI

Example:
González, M. and Patel, R. (2021) ‘Global Perspectives on Environmental Policy’, Environmental Studies Review, 6(1), pp. 23-35. https://doi.org/10.5678/esr.2021.001

Additional Notes:

  • Harvard style uses single quotes for article titles and italicizes journal names.
  • When there are three or more authors, only the first author is listed followed by “et al.”

To Sum it Up,

Citing research papers might seem a bit tricky at first, but once you know the basics of each citation style, it becomes much easier. Whether you’re working with APA, MLA, Chicago, IEEE, or Harvard style, each has its own rules to follow, and getting them right can make your work look polished and credible. 

Remember, proper citations show respect for other authors’ work and build trust in your own writing.

Frequently Asked Questions

How does a DOI give a reference to a research paper?

A DOI, or Digital Object Identifier, is a unique alphanumeric string assigned to a research paper or article, providing a permanent link to its online location. By including a DOI in your reference, you create a direct and reliable path to access the research paper, as the DOI remains constant even if the URL changes.

To reference a research paper using a DOI, simply add it at the end of the citation in the format required by your chosen citation style.

How do you cite a research paper in a sentence?

To cite a research paper in a sentence, include the author’s last name, publication year, and page number (if relevant), based on your citation style. For instance, in APA format, you would write: According to Smith (2021, p. 45), cultural factors play a critical role. Or in MLA format: Smith argues that "cultural factors are essential" (45). Always follow the specific guidelines of your citation style for precise formatting.
