A Quick Guide to Referencing | Cite Your Sources Correctly

Referencing means acknowledging the sources you have used in your writing. Including references helps you support your claims and ensures that you avoid plagiarism .

There are many referencing styles, but they usually consist of two things:

• A citation wherever you refer to a source in your text.
• A reference list or bibliography at the end listing full details of all your sources.

The most common method of referencing in UK universities is Harvard style , which uses author-date citations in the text. Our free Harvard Reference Generator automatically creates accurate references in this style.

Instantly correct all language mistakes in your text

Be assured that you'll submit flawless writing. Upload your document to correct all your mistakes.

Referencing styles, citing your sources with in-text citations, creating your reference list or bibliography, harvard referencing examples, frequently asked questions about referencing.

Each referencing style has different rules for presenting source information. For in-text citations, some use footnotes or endnotes , while others include the author’s surname and date of publication in brackets in the text.

The reference list or bibliography is presented differently in each style, with different rules for things like capitalisation, italics, and quotation marks in references.

Your university will usually tell you which referencing style to use; they may even have their own unique style. Always follow your university’s guidelines, and ask your tutor if you are unsure. The most common styles are summarised below.

Harvard referencing, the most commonly used style at UK universities, uses author–date in-text citations corresponding to an alphabetical bibliography or reference list at the end.

Harvard Referencing Guide

Vancouver referencing, used in biomedicine and other sciences, uses reference numbers in the text corresponding to a numbered reference list at the end.

Vancouver Referencing Guide

APA referencing, used in the social and behavioural sciences, uses author–date in-text citations corresponding to an alphabetical reference list at the end.

APA Referencing Guide APA Reference Generator

MHRA referencing, used in the humanities, uses footnotes in the text with source information, in addition to an alphabetised bibliography at the end.

MHRA Referencing Guide

OSCOLA referencing, used in law, uses footnotes in the text with source information, and an alphabetical bibliography at the end in longer texts.

OSCOLA Referencing Guide

Prevent plagiarism, run a free check.

In-text citations should be used whenever you quote, paraphrase, or refer to information from a source (e.g. a book, article, image, website, or video).

Quoting and paraphrasing

Quoting is when you directly copy some text from a source and enclose it in quotation marks to indicate that it is not your own writing.

Paraphrasing is when you rephrase the original source into your own words. In this case, you don’t use quotation marks, but you still need to include a citation.

In most referencing styles, page numbers are included when you’re quoting or paraphrasing a particular passage. If you are referring to the text as a whole, no page number is needed.

In-text citations

In-text citations are quick references to your sources. In Harvard referencing, you use the author’s surname and the date of publication in brackets.

Up to three authors are included in a Harvard in-text citation. If the source has more than three authors, include the first author followed by ‘ et al. ‘

The point of these citations is to direct your reader to the alphabetised reference list, where you give full information about each source. For example, to find the source cited above, the reader would look under ‘J’ in your reference list to find the title and publication details of the source.

Placement of in-text citations

In-text citations should be placed directly after the quotation or information they refer to, usually before a comma or full stop. If a sentence is supported by multiple sources, you can combine them in one set of brackets, separated by a semicolon.

If you mention the author’s name in the text already, you don’t include it in the citation, and you can place the citation immediately after the name.

• Another researcher warns that the results of this method are ‘inconsistent’ (Singh, 2018, p. 13) .
• Previous research has frequently illustrated the pitfalls of this method (Singh, 2018; Jones, 2016) .
• Singh (2018, p. 13) warns that the results of this method are ‘inconsistent’.

The terms ‘bibliography’ and ‘reference list’ are sometimes used interchangeably. Both refer to a list that contains full information on all the sources cited in your text. Sometimes ‘bibliography’ is used to mean a more extensive list, also containing sources that you consulted but did not cite in the text.

A reference list or bibliography is usually mandatory, since in-text citations typically don’t provide full source information. For styles that already include full source information in footnotes (e.g. OSCOLA and Chicago Style ), the bibliography is optional, although your university may still require you to include one.

Format of the reference list

Reference lists are usually alphabetised by authors’ last names. Each entry in the list appears on a new line, and a hanging indent is applied if an entry extends onto multiple lines.

Different source information is included for different source types. Each style provides detailed guidelines for exactly what information should be included and how it should be presented.

Below are some examples of reference list entries for common source types in Harvard style.

• Chapter of a book
• Journal article

Your university should tell you which referencing style to follow. If you’re unsure, check with a supervisor. Commonly used styles include:

• Harvard referencing , the most commonly used style in UK universities.
• MHRA , used in humanities subjects.
• APA , used in the social sciences.
• Vancouver , used in biomedicine.
• OSCOLA , used in law.

Your university may have its own referencing style guide.

If you are allowed to choose which style to follow, we recommend Harvard referencing, as it is a straightforward and widely used style.

References should be included in your text whenever you use words, ideas, or information from a source. A source can be anything from a book or journal article to a website or YouTube video.

If you don’t acknowledge your sources, you can get in trouble for plagiarism .

To avoid plagiarism , always include a reference when you use words, ideas or information from a source. This shows that you are not trying to pass the work of others off as your own.

You must also properly quote or paraphrase the source. If you’re not sure whether you’ve done this correctly, you can use the Scribbr Plagiarism Checker to find and correct any mistakes.

Harvard referencing uses an author–date system. Sources are cited by the author’s last name and the publication year in brackets. Each Harvard in-text citation corresponds to an entry in the alphabetised reference list at the end of the paper.

Vancouver referencing uses a numerical system. Sources are cited by a number in parentheses or superscript. Each number corresponds to a full reference at the end of the paper.

😕 What is an MLA Citation Generator?

An MLA citation generator is a software tool designed to automatically create academic citations in the Modern Language Association (MLA) citation format. The generator will take information such as document titles, author, and URLs as in input, and output fully formatted citations that can be inserted into the Works Cited page of an MLA-compliant academic paper.

The citations on a Works Cited page show the external sources that were used to write the main body of the academic paper, either directly as references and quotes, or indirectly as ideas.

👩‍🎓 Who uses an MLA Citation Generator?

MLA style is most often used by middle school and high school students in preparation for transition to college and further education. Ironically, MLA style is not actually used all that often beyond middle and high school, with APA (American Psychological Association) style being the favored style at colleges across the country.

It is also important at this level to learn why it's critical to cite sources, not just how to cite them.

🙌 Why should I use a Citation Generator?

Writing citations manually is time consuming and error prone. Automating this process with a citation generator is easy, straightforward, and gives accurate results. It's also easier to keep citations organized and in the correct order.

The Works Cited page contributes to the overall grade of a paper, so it is important to produce accurately formatted citations that follow the guidelines in the official MLA Handbook .

⚙️ How do I use MyBib's MLA Citation Generator?

It's super easy to create MLA style citations with our MLA Citation Generator. Scroll back up to the generator at the top of the page and select the type of source you're citing. Books, journal articles, and webpages are all examples of the types of sources our generator can cite automatically. Then either search for the source, or enter the details manually in the citation form.

The generator will produce a formatted MLA citation that can be copied and pasted directly into your document, or saved to MyBib as part of your overall Works Cited page (which can be downloaded fully later!).

MyBib supports the following for MLA style:

What Is Cite This For Me's Citation Generator?

Cite This For Me’s open-access generator is an automated citation machine that turns any of your sources into citations in just a click. Using a citation generator helps students to integrate referencing into their research and writing routine; turning a time-consuming ordeal into a simple task.

A citation machine is essentially a works cited generator that accesses information from across the web, drawing the relevant information into a fully-formatted bibliography that clearly presents all of the sources that have contributed to your work.

If you don’t know how to cite correctly, or have a fast-approaching deadline, Cite This For Me’s accurate and intuitive citation machine will lend you the confidence to realise your full academic potential. In order to get a grade that reflects all your hard work, your citations must be accurate and complete. Using a citation maker to create your references not only saves you time but also ensures that you don’t lose valuable marks on your assignment.

Not sure how to format your citations, what citations are, or just want to find out more about Cite This For Me’s citation machine? This guide outlines everything you need to know to equip yourself with the know-how and confidence to research and cite a wide range of diverse sources in your work.

Why Do I Need To Cite?

Simply put, referencing is the citing of sources used in essays, articles, research, conferences etc. When another source contributes to your work, you have to give the original owner the appropriate credit. After all, you wouldn’t steal someone else’s possessions so why would you steal their ideas?

Any factual material or ideas you take from another source must be acknowledged in a reference, unless it is common knowledge (e.g. President Kennedy was killed in 1963). Failing to credit all of your sources, even when you’ve paraphrased or completely reworded the information, is plagiarism. Plagiarizing will result in disciplinary action, which can range from losing precious points on your assignment to expulsion from your university.

What’s more, attributing your research infuses credibility and authority into your work, both by supporting your own ideas and by demonstrating the breadth of your research. For many students, crediting sources can be a confusing and tedious process, but it’s a surefire way to improve the quality of your work so it’s essential to get it right. Luckily for you, using Cite This For Me’s citation machine makes creating accurate references easier than ever, leaving more time for you to excel in your studies.

In summary, the referencing process serves three main functions:

• To validate the statements and conclusions in your work by providing directions to other sound sources that support and verify them.
• To help your readers locate, read and check your sources, as well as establishing their contribution to your work.
• To give credit to the original author and hence avoid committing intellectual property theft (known as ‘plagiarism’ in academia).

How Do I Cite My Sources With The Cite This For Me's Citation Machine?

Cite This For Me’s citation generator is the most accurate citation machine available, so whether you’re not sure how to format in-text citations or are looking for a foolproof solution to automate a fully-formatted works cited list, this citation machine will solve all of your referencing needs.

Referencing your source material doesn’t just prevent you from losing valuable marks for plagiarism, it also provides all of the information to help your reader find for themselves the book, article, or other item you are citing. The accessible interface of this citation builder makes it easy for you to identify the source you have used – simply enter its unique identifier into the citation machine search bar. If this information is not available you can search for the title or author instead, and then select from the search results that appear below the citation generator.

The good news is that by using tools such as Cite This For Me, which help you work smarter, you don’t need to limit your research to sources that are traditional to cite. In fact, there are no limits to what you can reference, whether it be a YouTube video, website or a tweet.

To use the works cited generator, simply:

• Select from APA, MLA, Chicago, ASA, IEEE and AMA * styles.
• Choose the type of source you would like to cite (e.g. website, book, journal, video).
• Enter the URL , DOI , ISBN , title, or other unique source information into the citation generator to find your source.
• Click the ‘Cite’ button on the citation machine.
• Copy your new reference from the citation generator into your bibliography or works cited list.
• Repeat for each source that has contributed to your work.

*If you require another referencing style for your paper, essay or other academic work, you can select from over 7,500 styles.

Once you have created your Cite This For Me account you will be able to use the citation machine to generate multiple references and save them into a project. Use the highly-rated iOS or Android apps to create references in a flash with your smartphone camera, export your complete bibliography in one go, and much more.

What Will The Citation Machine Create For Me?

Cite This For Me’s citation maker will generate your reference in two parts; an in-text citation and a full reference to be copied straight into your work.

The citation machine will auto-generate the correct formatting for your works cited list or bibliography depending on your chosen style. For instance, if you select a parenthetical style on the citation machine it will generate an in-text citation in parentheses, along with a full reference to slot into your bibliography. Likewise, if the citation generator is set to a footnote style then it will create a fully-formatted reference for your reference page and bibliography, as well as a corresponding footnote to insert at the bottom of the page containing the relevant source.

Parenthetical referencing examples:

In-text example: A nation has been defined as an imagined community (Anderson, 2006).* Alternative format: Anderson (2006) defined a nation as an imagined community.

*The citation machine will create your references in the first style, but this should be edited if the author’s name already appears in the text.

Bibliography / Works Cited list example: Anderson, B. (2006). Imagined Communities. London: Verso.

What Are Citation Styles?

A citation style is a set of rules that you, as an academic writer, must follow to ensure the quality and relevance of your work. There are thousands of styles that are used in different academic institutions around the world, but in the US the most common are APA, MLA and Chicago.

The style you need to use will depend on the preference of your professor, discipline or academic institution – so if you’re unsure which style you should be using, consult your department and follow their guidelines exactly, as this is what you’ll be evaluated on when it comes to grading.

Referencing isn’t just there to guard against plagiarism – presenting your research in a clear and consistent way eases the reader’s comprehension. Each style has a different set of rules for both page formatting and referencing. Be sure to adhere to formatting rules such as font type, font size and line spacing to ensure that your work is easily legible. Furthermore, if your work is published as part of an anthology or collected works, each entry will need to be presented in the same style to maintain uniformity throughout. It is important to make sure that you don’t jump from one style to another, so follow the rules carefully to ensure your reference page and bibliography are both accurate and complete.

If you need a hand with your referencing then why not try Cite This For Me’s citation builder? It’s the quickest and easiest way to reference any source, in any style. The citation generator above will create your references in MLA format style as standard, but this powerful citation machine can generate fully-formatted references in thousands of the widely used global college styles – including individual university variations of each style. So, whether your subject requires you to use the APA citation , or your professor has asked you to adopt the Chicago style citation so that your work includes numbered footnotes, we’re sure to have the style you need. Cite This For Me also offers a citation machine and helpful formatting guide for styles such as ASA , IEEE or AMA . To access all of them, simply create your free account and search for your specific style.

How Do I Format A Works Cited List Or Bibliography?

Drawing on a wide range of sources greatly enhances the quality of your work, and reading above and beyond your recommended reading list – and then using these sources to support your own thesis – is an excellent way to impress your reader. A clearly presented works cited list or bibliography demonstrates the lengths you have gone to in researching your chosen topic.

Typically, a works cited list starts on a new page at the end of the main body of text and includes a complete list of the sources you have actually cited in your paper. This list should contain all the information needed for the reader to locate the original source of the information, quote or statistic that directly contributed to your work. On the other hand, a bibliography is a comprehensive list of all the material you may have consulted throughout your research and writing process. Both provide the necessary information for readers to retrieve and check the sources cited in your work.

Each style’s guidelines will define the terminology of ‘ works cited ’ and ‘ bibliography ’, as well as providing formatting guidelines for font, line spacing and page indentations. In addition, it will instruct you on how to order your works cited list or bibliography – this will usually be either alphabetical or chronological (meaning the order that these sources appear in your work). Before submitting your work, be sure to check that you have formatted your whole paper – including your reference page and bibliography – according to your style’s formatting guidelines.

Sounds complicated? Referencing has never been so easy; Cite This For Me’s citation machine will automatically generate fully-formatted references for your works cited page or bibliography in your chosen style. Sign in to your Cite This For Me account to save and export your bibliography straight into Microsoft Word, Evernote, EndNote and more. If that sounds like too much work.

How Do Citations Actually Work?

Although the citation generator will create your bibliography and works cited list for you in record time, it is still useful to understand how this system works behind the scenes. Understanding how a citation machine actually generates references will greatly increase the quality of your work.

As well as saving you time with its citation maker, Cite This For Me provides the learning resources to help you fully understand the citing process and the benefits of adopting great referencing standards.

The referencing process:

• Find a book, journal, website or other source that will contribute to your work.
• Save the quote, image, data or other information that you will use in your work.
• Save the source information that enables you to find it again (i.e. URL, ISBN, DOI etc.).
• Format the source information into a reference.
• Copy and paste the reference into the body of the text.
• Repeat for each source that contributes to your work.
• Export or copy and paste the fully-formatted reference into your bibliography.

When to Cite a Source in a Paper

And What Is Common Knowledge?

"Write an essay and back it up with facts."

How many times have you heard a teacher or professor say this? But many students might wonder what exactly counts as a fact, and what doesn't. That means they don't know when it is proper to cite a source, and when it's OK not to use a citation.

Dictionary.com states that a fact is:

• Something demonstrated to exist or known to have existed.

"Demonstrated" is a hint here. What the teacher means when she/he tells you to use facts is that you need to back up your claims with some evidence that supports your claims (sources). It's one trick that teachers use to make sure you actually use some references when you write a paper, instead of simply offering a list of your opinions.

This may sound easy, but it's actually tough sometimes to know when you need to back up a statement with evidence and when it is fine to leave a statement unsupported.

When to Cite a Source

You should use evidence ( citations ) any time you make a claim that is not based on a well-known fact or common knowledge. Here's a list of situations when your teacher would expect a citation:

• You make a specific claim that could be challenged--like London is the foggiest city in the world. 
• You quote somebody.
• You make a specific claim that is not common knowledge like the Indian Ocean is the youngest of the world's major oceans.
• You paraphrase information from a source (give the meaning but change the wording).
• Offer an authoritative (expert) opinion--like "germs cause pneumonia."
• You got an idea from somebody else, even through email or conversation.

Although there may be interesting facts that you have believed or know for many years, you will be expected to provide proof of those facts when you're writing a paper for school.

Examples of Claims You Should Support

• Hot water can freeze faster than cold water.
• Poodles are friendlier than Dalmatians.
• American Chestnut trees are nearly extinct.
• Eating while driving is more dangerous than talking on the cell phone while driving.
• Thomas Edison invented a vote counter.

When You Don't Need to Cite a Source

So how do you know when you do not need to cite a source? Common knowledge is basically a fact that practically everyone knows, like the fact that George Washington was a U.S. president.

More Examples of Common Knowledge or Well-Known Facts

• Bears hibernate in the winter.
• Fresh water freezes at 32 degrees F.
• Many trees shed their leaves in the fall.
• Some trees do not shed their leaves in the fall.
• Bears hibernate.

A well-known fact is something that many people know, but it is also something that a reader could look up easily if he/she didn't know.

• It's best to plant flowers in the early spring.
• Holland is famous for its tulips.
• Canada has a multilingual population.

If you're not really certain about something being common knowledge, you could give it the little sister test. If you have a younger sibling, ask him or her the subject you're pondering. If you get an answer, it could be common knowledge!

A Good Rule of Thumb

A good rule of thumb for any writer is to go ahead and use a citation when you're not certain whether or not the citation is necessary. The only risk in doing this is littering your paper with unnecessary citations that will drive your teacher crazy. Too many citations will give your teacher the impression that you are attempting to stretch your paper to a certain word count!

Simply trust your own best judgment and be honest with yourself. You'll get the hang of it soon!

Up, Up and Not OK: Letting Go of Balloons Could Soon Be Illegal in Florida

In an effort to curb microplastics and marine pollution, state lawmakers voted to ban intentional releases.

By Cara Buckley

Balloons released in the sky don’t go to heaven. They often end up in oceans and waterways, where they’re 32 times more likely to kill seabirds than other types of plastic debris. Despite this, humans like to release them en masse, be it to celebrate a loved one’s life or a wedding, or to reveal the gender of a baby.

The practice is on the verge of becoming illegal in Florida, where the legislature has joined a growing number of states to ban the intentional release of balloons outdoors. The Florida ban is expected to be signed by Gov. Ron DeSantis and would take effect July 1.

Florida is at the forefront of a dizzying and contentious array of statewide bans, outlawing lab grown meat , certain books from school libraries and classrooms, and most abortions after six weeks . But the balloon ban is rare for garnering widespread bipartisan support. It was championed by environmentalists and sponsored by two Republican lawmakers from the Tampa Bay area, Linda Chaney, a state representative and Nick DiCeglie, a state senator.

“Balloons contribute to the increase in microplastic pollution which is harmful to every living thing including humans, polluting our air and drinking water,” Ms. Chaney wrote in an email.

“My hope is that this bill changes the culture, making people more aware of litter in general, including balloons,” she said.

Ms. Chaney said she first heard about the perils of balloon debris in 2020. Aquatic animals often mistake balloons for jellyfish and feel full after eating them, essentially starving from the inside out. Ribbons affixed to balloons entangle turtles and manatees. Balloons also pose a threat to land animals. In her research, Ms. Chaney learned about a pregnant cow that died after ingesting a balloon while grazing. The unborn calf died too.

The bill closes a loophole in an existing Florida law that allowed for the outdoor release of up to nine balloons per person in any 24-hour period, a provision that critics say didn’t achieve the goal of reducing marine trash.

The new legislation makes it clear that balloons can pose an environmental hazard, supporters say. It equates intentionally releasing a balloon filled with a gas lighter than air with littering, a noncriminal offense that carries a fine of $150. The ban also applies to outdoor releases of any balloons described by manufacturers as biodegradable.

The ban does not restrict the sale of balloons by party suppliers or manufacturers; they could still be used indoors or as decorations outdoors if properly secured.

Balloons released by a government agency or for government sanctioned scientific purposes would be exempt from the new law. Hot air balloons recovered after launch or balloons released by children aged 6 and younger would also be exempt.

The bill counts among its supporters the Florida Retail Association as well as the Coalition for Responsible Celebration, a trade association for balloon distributors and party stores, which in a statement said it recognized “the importance of promoting responsible balloon usage and ensuring safe access to these joy-inspiring products.”

The legislation marks a win for environmentalists hamstrung by Florida legislation known as the “ban on bans,” which prohibits counties and local municipalities from regulating single use plastics and plastic bags.

Jon Paul “J. P.” Brooker, director of Florida conservation for the nonprofit group Ocean Conservancy, said that increased concern about the health of beaches, a major driver of tourism, helped conservationists and lawmakers find common ground.

“Florida is its beaches,” Mr. Brooker said, “People are not going to flock by millions to them if they’re trashed and there’s dead animals and plastic and trash all over.”

Mr. Brooker said while it remains to be seen how vigorously police will enforce the ban, the fact that they will be able to issue tickets was a good thing. “More than anything,” he added,” it gives us in the environmental community an opportunity to educate the public as to why it’s bad.”

Public sentiment in Florida against balloon releases has been growing. Earlier this year, the city of Miami Beach adopted an ordinance banning party balloons from public marinas, marine facilities, parks and public beaches. This followed the arrest of two people in 2022 who were filmed popping balloons aboard a chartered yacht and letting the remnants fall into Biscayne Bay.

The balloon release ban follows another environmental win in the state. For more than 30 years, Mr. Brooker said cigarettes were the number one form of trash found on the state’s beaches. Then in 2022, the state passed a law allowing local governments to restrict cigarette smoking and vaping on public beaches and parks. More than 50 counties and municipalities, accounting for more than 500 miles of the state’s 1,350 miles of coastline, have since outlawed smoking and vaping on beaches, Mr. Brooker said.

“This isn’t just the bailiwick of progressives, and it’s certainly not something that draws the enmity of conservatives,” Mr. Brooker said. “It’s all Floridians banding together to protect Florida’s beaches that are the backbone of our economy and the underpinning of our cultural identity.”

According to Emma Haydocy, Florida policy manager for the Surfrider Foundation, seven other states have cracked down on outdoor balloon releases. And just last week, lawmakers in North Carolina filed their version of the Florida legislation.

In lieu of releasing balloons, conservationists are urging people to instead plant a tree or toss flower petals into the water.

“There are so many other ways of celebrating that are not detrimental,” Ms. Haydocy said.
