Supports your claims with credible evidence
Provides traceability for readers to explore original sources
Builds your credibility as a researcher

Types of References in Research Articles

There are two major components:

In-text citations – brief references within the body of your article
Reference list (or bibliography) – detailed list of all sources at the end

Popular Referencing Styles (with Examples)

Different journals and academic fields use different citation styles. Here are the most common ones:

APA Style (American Psychological Association) – Common in Social Sciences

In-text citation:

(Smith, 2022)

Reference list format:

Smith, J. (2022). Environmental changes and society. Green Press.

MLA Style (Modern Language Association) – Common in Humanities

In-text citation:

(Smith 22)

Works Cited format:

Smith, John. Environmental Changes and Society. Green Press, 2022.

Chicago Style – Used in History and some other disciplines

How to Write References Step-by-Step

Writing references in a research article can feel tricky, but it becomes easy when you follow a clear process. This step-by-step guide will help you understand how to collect, format, and insert references correctly, using simple language and practical tips.

Step 1: Know What Citation Style to Use

Before writing any references, check which citation style is required. Different journals, universities, or teachers ask for specific styles like:

APA (used in psychology, social sciences)
MLA (used in literature and humanities)
IEEE (used in engineering and technology)
Vancouver (used in medical and health sciences)
Chicago (used in history and arts)

Tip: Always read the journal or assignment guidelines to know the exact style you must follow.

Step 2: Keep Track of Every Source You Use

While reading books, articles, or websites for your research, write down important details of each source:

Author’s full name
Year of publication
Title of the book, article, or webpage
Name of the journal or publisher
Volume and issue number (for journals)
Page numbers
DOI or website URL (for online sources)

Tip: Use a notebook, Word file, or a reference manager (like Zotero or Mendeley) to store this information.

Step 3: Add In-Text Citations While Writing

When you quote, paraphrase, or refer to someone else's work, you must show where that idea came from.

Different styles use different formats. For example:

APA: (Smith, 2022)
MLA: (Smith 45)
IEEE: [1]
Vancouver: (1)

Place the in-text citation right after the sentence that includes the information from the source.

Tip: Even if you rephrase the information in your own words (paraphrasing), you must still cite the source.

Step 4: Create the Reference List at the End

At the end of your article, you must add a list of all the sources you cited. This is called the “Reference List” or “Bibliography”, depending on the citation style.

Some basic examples:

APA:
- Smith, J. (2022). Climate and Society. Green Press.
IEEE:
- [1] J. Smith, Climate and Society, Green Press, 2022.
Vancouver:
- Smith J. Climate and Society. Green Press; 2022.

The format includes author name, title, year, and other details in a specific order, so always follow the exact style guide.

Tip: The reference list should only include the works that were actually cited in your article.

Step 5: Use the Correct Formatting Rules

Each style has different formatting rules. Here are some common points to watch:

Use italics for book or journal titles in APA, MLA, or Chicago
Put author’s last name first, followed by initials
Include full publication year
Alphabetize your list (APA, MLA, Chicago) or number them in the order they appear (IEEE, Vancouver)
Use proper punctuation — commas, periods, and colons must be placed exactly as required

Tip: Refer to official style guides or use trusted online tools like Cite This For Me, ZoteroBib, or Google Docs citation tools.

Step 6: Double-Check Everything

Before submitting your research article:

Make sure all in-text citations have a matching entry in the reference list
Check that names, dates, and titles are spelled correctly
Test all URLs or DOIs to make sure they work
Use the same citation style throughout your paper — don’t mix styles

Tip: Many plagiarism checkers also highlight missing citations, so it’s useful to run one final scan.

Common Referencing Mistakes to Avoid

Using inconsistent citation styles
Forgetting to cite paraphrased content
Missing references in the final list
Incorrect author names or publication dates
Broken URLs or missing DOIs for online sources

Tips for Referencing:

Keep track of sources from the beginning
Use reference management software
Always double-check journal guidelines
When in doubt, cite the source
Avoid relying solely on AI-generated references—verify accuracy

Frequently Asked Questions (FAQs)
