In academic writing, citing sources is critical. You must include a citation that gives credit to the original author if you utilize information or ideas from a source (such as a book, article, or web page).

There are numerous citation styles, each with its own set of formatting criteria. APA and MLA are the most used citation styles.

The Scribbr Citation Generator, which is available for free, is the quickest way to reference sources in these formats. Simply type in the URL, DOI, or title, and we’ll find the information you need.

When should you cite sources?

In all scholarly texts, citations are required (such as essays, research papers, and dissertations). You must cite a source every time you use it to draw on ideas, summarize facts, make arguments, or give examples.

You can quote or paraphrase the original text to refer to a source:

• To quote a source, copy a brief passage word for word and place it within quotation marks.

• To paraphrase, rewrite the source text in your own terms. It’s critical that the paraphrase doesn’t sound too much like the original.

To avoid plagiarism, whether you quote or paraphrase, you must always add a citation. Citing also helps your reader to locate the original source for themselves, enhancing the credibility of your article.

Remember to reference any other sources you utilize for ideas, examples, or evidence, in addition to scholarly materials like books and journal articles. Websites, YouTube videos, dictionaries, seminars, and social media posts all fall under this category.

What style of citation should you use?

Check the requirements first because many university departments and academic journals require a specific citation style. If no citation style is mentioned, you must select one and adhere to it throughout your paper.

Your best option is determined by your field and discipline. In the social sciences, APA is the most popular style, whereas in the humanities, MLA is the most popular. Other fields, such as medicine or engineering, have their own distinct styles.

You can find out what style your instructor uses by asking them or reading previous papers in your field.

In-text references

In-text citations are usually written in parenthesis and include the author’s last name as well as a year or page number (depending on the citation style). Footnotes, endnotes, or bracketed numerals that match reference entries are used in some styles.

Each citation style has its own set of criteria for citing:

• sources with a number of writers

• sources with no author information

• sources with an unclear publication date

• sources that don’t have page numbers

• a single author’s many sources

These guidelines are fully detailed in our style-specific instructions to in-text citations.
