It is one of the most widely requested referencing style guides across US and UK universities. The most current version is APA 7th edition, published in 2020.

Introduction to Referencing: Referencing in APA Style

APA format uses an author-date in-text citation system. Every source mentioned in your text must appear in a reference list at the end of your work. Each entry must include the author, date, title, and source. This introduction to referencing in APA style covers what you need to know whether you are working on a research paper, coursework, or dissertation.

Key APA format features include:

• Double-spaced text throughout (yes, APA is double spaced)

• 12-point Times New Roman or 11-point Calibri font

• One-inch margins on all sides

• A title page with the paper title, author name, institution, course, instructor, and date

• A running head is no longer required for student papers in APA 7th edition

• In-text citations using (Author, Year) format

• A References page at the end in alphabetical order

How to Cite in APA In-Text

APA in-text citations follow the format: (Author, Year) or (Author, Year, p. X) for direct quotes. Knowing how to do in-text citations in APA and how to cite in APA format correctly is essential to avoid plagiarism penalties.

• Direct quote: "Referencing strengthens academic writing" (Jones, 2020, p. 45).

• Multiple authors: For two authors use (Smith & Jones, 2021). For three or more authors in APA 7th edition, use the first author followed by et al.: (Williams et al., 2019). Knowing how to cite multiple authors in APA correctly avoids common formatting mistakes.

A Student Guide: How to Reference for A Level Coursework

If you are studying at A Level in the UK, referencing may be required depending on your subject and exam board. Subjects like History, English Literature, Sociology, and Psychology often require students to cite sources within coursework submissions. This student guide covers how to write references for A Level coursework and what to do when your teacher does not specify a style.

Which Style Should A Level Students Use?

A Level students are not always given a specific referencing style. If your teacher specifies MLA, APA, Harvard, or MHRA, follow that instruction. If not, Harvard referencing is the most commonly recommended style for UK school students. Harvard style of referencing uses an author-date system and is straightforward to apply consistently across a coursework document.

When writing A Level coursework with references:

• Always include in-text citations when quoting or paraphrasing

• Compile a full bibliography or reference list at the end

• Be consistent in your harvard style references throughout the document

• Cite all sources including books, articles, websites, and videos

How to Reference Coursework Example (Harvard)

Here is a how to reference coursework example using Harvard style. If your teacher asks how to reference coursework in APA, APA 7th edition, or APA format, the examples in the APA section above apply directly.

Harvard in-text: (Smith, 2021)

Harvard reference list:

Smith, J. (2021) The causes of World War One. London: Pearson.

For how to reference course material in Harvard style, use the same author-date format but replace the publisher details with the institution or course module name. The Harvard style reference list entry should always include author, year, title, place of publication, and publisher.

Advice: Referencing Facts and Ideas in Your Coursework

A common question students ask is whether they need to reference facts, not just direct quotes. The answer is yes. Any fact, statistic, idea, or argument that comes from another source must be cited, even if you have reworded it completely. Failure to do so constitutes plagiarism. This advice on referencing facts and ideas in your coursework applies regardless of which style you use.

If you are struggling to keep track of your sources alongside writing your actual essay, our essay writing service can help you produce a fully referenced, submission-ready piece.

Citation Styles Explained for Students (APA, MLA, Chicago, Harvard and Vancouver Guide)

There are many referencing systems used across academia. To learn APA, MLA, Chicago, Harvard, and Vancouver formats and explore popular referencing style guides like APA, MLA, and Harvard, this section gives you a clear overview of each. This citation styles overview covers APA, MLA, Chicago, Turabian, and IEEE alongside the styles most commonly required in coursework.

APA (American Psychological Association)

Discipline: Social sciences, psychology, education, nursing, business

System: Author-date in-text citations with a References page

APA referencing styles and APA citation styles are widely used in US universities and increasingly adopted in the UK for science-adjacent subjects. APA style is the go-to referencing style guide for social sciences and health subjects. What is APA? APA stands for American Psychological Association, and what is APA style is a common question from first-year students. APA style means following the formatting and citation rules published in the APA Publication Manual, now in its 7th edition.

MLA Style (Modern Language Association)

Discipline: Humanities, literature, languages, cultural studies

What is MLA style? MLA style is the referencing system developed by the Modern Language Association for use in humanities subjects including English literature, linguistics, film, and cultural studies. What is MLA style writing? It means producing essays with (Author Page) in-text citations and a Works Cited page. What is MLA style format? It requires specific heading, header, and spacing rules. What is MLA style citation? It is a parenthetical citation using the author's last name and page number.

The MLA system is a parenthetical system that uses (Author Page) in-text rather than (Author, Year). What does MLA style mean in practice: no separate title page for standard essays, a specific MLA style heading in the top-left corner, and an MLA style header with your last name and page number in the top right.

MLA style format features include:

• Works Cited page (not References or Bibliography): This is the MLA style bibliography

• MLA style in-text citation: (Thompson 45): No comma between name and page number

• Hanging indent on Works Cited entries: This is correct MLA style citation format

• MLA style is double spaced throughout including the Works Cited page

• MLA style heading includes your name, instructor, course, and date in the top left corner

• MLA style header: your last name and page number in the top right of every page

• How should the date be written in MLA style? Day Month Year, for example: 14 June 2026

Which in-text citation is formatted correctly in MLA style? The correct format is (Thompson 45) with no comma. (Thompson, 45) or (Thompson, 2023) are incorrect in MLA.

Chicago Style

Chicago style is commonly used in history, arts, and some social sciences. Chicago style features two distinct systems:

• Notes-Bibliography (NB): Uses chicago style footnotes or endnotes plus a chicago style bibliography. Common in humanities subjects including history, theology, and the arts.

• Author-Date (AD): Uses chicago style in-text citation format similar to APA. Common in sciences and social sciences.

Chicago style format requires a chicago style title page with the title, your name, course, instructor, and date centered on the page. The chicago style paper format also requires double-spaced body text and footnotes chicago style at the bottom of each page where the citation appears. A chicago style citation example in footnote format looks like: Rachel Thompson, Critical Thinking in Higher Education (Sage, 2023), 45. A chicago style essay follows these formatting rules throughout. A chicago style paper example and chicago style paper can be found in the Chicago Manual of Style. For how to cite chicago style and how to cite in chicago style, see the book citation examples above. A chicago style citation generator can also help you format entries quickly.

Harvard Style Referencing

Harvard style referencing uses an author-date system. Harvard style of referencing and harvard style of writing are widely used in UK universities across business, law, education, and the social sciences. Harvard style citation format in-text: (Author, Year). Harvard style references in the reference list include the author, year, title, place of publication, and publisher.

The harvard style reference list is presented alphabetically at the end of the document. A harvard style bibliography follows the same format but may include sources consulted as well as cited. Harvard style citation differs from APA in punctuation and capitalization rules. For how to reference in harvard style, follow the author-date format and check your institution's specific variant.

Vancouver Style

Vancouver is a numbered referencing system used primarily in medicine, nursing, and the health sciences. Sources are numbered sequentially as they appear in the text, and the reference list presents them in that numerical order rather than alphabetically.

Example in-text: Patients with chronic conditions showed improved outcomes [3].

OSCOLA

OSCOLA (Oxford University Standard for Citation of Legal Authorities) is used exclusively in law. It uses footnotes rather than in-text citations and has specific rules for citing cases, legislation, books, and journal articles.

MHRA

MHRA (Modern Humanities Research Association) style is common in UK humanities departments, particularly for languages and literary studies. Like Chicago, it uses footnotes and a bibliography. When choosing between MLA, APA, Harvard, or MHRA, MHRA is most relevant to UK language and literature students. For citing sources, a Harvard guide to using sources from your institution will clarify the exact variant your department expects. MLA style here and APA style differ most visibly in how in-text citations are formatted and how the end list is titled.

Referencing Styles: References, Citations and Avoiding Plagiarism

Referencing and avoiding plagiarism are inseparable. Plagiarism occurs when you use someone else's words, ideas, data, or images without giving credit. It can be intentional or accidental, but the consequences are the same: academic penalties, failed coursework, or in serious cases, expulsion. Every student using referencing style guides; whether they follow APA referencing styles, Harvard style citation, MLA style citations, or Chicago style citations must understand what plagiarism is and how referencing prevents it.

What Counts as Plagiarism?

• Copying text from a source without quotation marks or a chicago style in-text citation or APA in-text citation

• Paraphrasing an argument without acknowledging the original author

• Using statistics, data, or charts without citing the source; citing sources using a Harvard guide to using sources or equivalent is essential

• Submitting someone else's work as your own

• Self-plagiarism: reusing your own previous work without declaration

How to Avoid Plagiarism Through Referencing

The simplest way to avoid plagiarism is to cite every source you use. This means:

• Adding an in-text citation every time you quote, paraphrase, or summarise

• Including full details in your reference list or bibliography

• Using quotation marks for any direct quotes

• Making sure your paraphrase is genuinely reworded, not just slightly altered

What are the 4 Types of Referencing Styles?

What are the 4 types of referencing styles? The four most commonly taught are APA, Harvard, MLA, and Chicago. But there are more: Vancouver, OSCOLA, MHRA, Turabian, and IEEE are used in specific disciplines.

MLA vs APA vs Chicago vs Harvard: Key Differences

The 10 differences between MLA and APA include: in-text citation format, reference list title, treatment of author names, use of page numbers, date placement, capitalization of titles, journal article formatting, edition information, how multiple authors are handled, and the discipline each style is designed for.

APA, MLA, and Chicago style differences relate primarily to who the intended audience is. APA is scientific and data-forward. MLA is humanities-focused and text-forward. Chicago is flexible and used most in history and publishing. For a full breakdown of what is APA style versus MLA and Chicago, and how Harvard compares, see the table in the Choosing the Right Citation Style section above.
