Online Plagiarism Checker For Students

Writing an academic paper can be challenging when you’re not sure if it’s original enough to pass a plagiarism check. Of course, students take information from various sites before writing their own text. Sometimes, it just so happens that certain parts are very similar to your resources, making your professor think that you’ve just copied work from somewhere. That’s why it’s crucial for any modern college or university student to ensure that their work has 100% original content to maintain academic integrity.

Luckily, a free plagiarism checker online can solve this issue quickly and easily. Many cheap essay writing services use a plagiarism checker for research paper. However, students sometimes forget that they should too. But with so many options that pop up when you ask Google to “check my paper for plagiarism”, how do you choose the right one for detection? We’ve got the solution in the form of PapersOwl’s free plagiarism checker tool! Our simple tool makes it convenient to check any writing task without having to spend a dime. It works quickly and highly accurately, ensuring that you get the top grade you deserve. So, if you want to check plagiarism online before turning your task in, head over to our website and get started!

Accurate Check for Plagiarism with Percentage

Many students wishing to produce original content aren’t quite sure how to get an exact percentage of plagiarised text in their work. This percentage is important since many universities have a certain limit of non-unique words you can have in your essay for it to be considered okay. If your plagiarism search doesn’t give you the exact percentage, you can’t be sure if your assignment will go through or not.

When using a free plagiarism tool, it’s essential to have this data provided to you. Only when you have it can you decide which parts to change and which ones to chuck out to achieve your desired results. Plagiarized content is a big issue in modern educational institutions, so getting reliable and trustworthy results is vital. This is the most essential requirement when you check plagiarism.

PapersOwl’s plagiarism detection tool gives you all the information you need to fix plagiarized content. Whether you’ve fallen victim to accidental plagiarism or have tried to make your life easier by copying some text from different sources, you’ll get an accurate percentage with our plagiarism checker online. If you’re wondering how to check paper for plagiarism, it’s nothing complicated at all! Simply visit our site, paste your whole essay into the relevant text box or upload the text file, click on Check For Plagiarism, and you’ll get accurate plagiarism results in a matter of seconds. You’ll see the problematic parts with plagiarism detected highlighted, with links to where similar content exists. Our service with plagiarism detector will also give you the option to check my essay for plagiarism and then to hire a professional paper writer to fix your task quickly if you're busy with other things!

The Fastest Plagiarism Checker Online

Gaining insight into duplicate content only works if you get your results quickly. There are so many free plagiarism software online that promise to do the job for you. However, a lot of them are clunky, slow, and inaccurate. How can you produce original work without similarity detection you can trust?

PapersOwl stands out in this regard because it will detect plagiarism in seconds. This is a plagiarism scanner that’s able to perform a Swift Check to give you a uniqueness check right there and then. It also conducts a Deep Search, going through millions of sources on the internet to check for plagiarism. A document of about 1500 words takes only about 10 seconds to get processed! You get a clear plagiarism score of how much text is plagiarized and how much is original. All the sources that your essay matches are listed based on how much similarity there is in your academic writing. And on top of that, you get a handy Make It Unique button that’ll take you to an order page where you can ask our expert writers to rewrite your work and make it 100% unique.

All of this is done almost instantly, allowing students to continue do assignments without missing a beat. Not every plagiarism detection software works this quickly, making ours the best one you’ll ever use.

Plagiarism Checker Helps Boost Your Grade

A lot of students make the mistake of considering their papers automatically free from plagiarism. After all, they’ve written it themselves, so how could it be problematic? What they don’t realize is that it’s very easy to borrow some information mistakenly. Turning such a paper in can cause multiple problems, as your professor might think you haven’t done the work at all.

That is why you should always use a plagiarism scanner to test for plagiarized content in your college papers. Our online plagiarism checker for students is designed for this exact purpose. A simple, free plagiarism check could help you check plagiarism, fix any mistakes you see, and submit high-quality text that no one will question.

Our plagiarism detector has a lot going for it. It makes plagiarism detection easier than ever before. Unlike copying and pasting each passage individually into Google, simply upload the whole file into our plagiarism checker free for students, and you don’t have to do anything else. All the matches are highlighted so you know what to change.

The plagiarism test will give you a uniqueness percentage too. This will help you figure out where you stand and how much time you need to adjust anything if required. So, using our copyright checker online free to check your writing is essential. This way, you’ll submit the task only when you’re sure it meets the level of uniqueness required by your school. As a result, your grades will drastically improve when you check for plagiarism.

Plagiarism Checker FAQ

What is plagiarism.

Plagiarism is the act of representing someone else’s work as your own. In educational contexts, definitions vary by institution. It includes direct copying, improper paraphrasing, and self-plagiarism, where one reuses their own work without citation. Plagiarism violates academic integrity and journalistic ethics. In academic writing, producing original work and appropriately crediting sources prevents plagiarized content. Accidental plagiarism occurs when sources are unintentionally cited incorrectly, underscoring the importance of understanding citation practices. Maintaining originality and avoiding plagiarism not only uphold academic integrity but also contribute to creating original content that advances knowledge and scholarship.

What percentage of a paper can be plagiarized (or copied) and still be considered unique?

Generally speaking, similar or exact copies of another source should be kept under 15% for the total text of the article/paper/essay. As a best practice, citations should be used whenever using another original source word-for-word.

What’s the difference between deliberate and accidental plagiarism?

Deliberate plagiarism is purposely copying works from books, articles, webpages, or someone else’s paper and representing it as your original work. Alternatively, accidental plagiarism occurs in a few different ways:

• Incorrectly citing another person’s works
• Failing to paraphrase another person’s works - even when citing it correctly
• Reusing your own previous papers and inadvertently representing it as a new idea

A plagiarism checker works by comparing the submitted copy against known existing content. This sort of similarity checker flags instances of duplicate content, allowing the writer to modify those areas to avoid any claims of plagiarism.

What are the consequences of plagiarism?

The consequences of plagiarizing another person’s work vary by profession. For Students: Maintaining academic integrity is crucial. Students must ensure their work is not plagiarized. Consequences include failing grades, removal from classes, or expulsion. Even if allowed to stay, students may face mistrust and scrutiny. For Copywriters: Copywriters must produce original content. Plagiarized content can damage their reputation and make it hard to get assignments. Ensuring 100% originality is their responsibility. For Journalists: Journalists must uphold high standards of integrity. Plagiarized content erodes trust with readers and publishers, potentially ending careers. They must produce original, well-cited content.

Why is plagiarism bad?

There are several reasons why plagiarism is wrong, all centering around violating academic integrity, undermining originality, and eroding trust. It leads to legal consequences, tarnishes reputations, and stunts personal growth. Avoiding plagiarism preserves credibility, fosters creativity, and upholds ethical standards. Educational institutions and search engines penalize plagiarized content, impacting SEO rankings and visibility. Embracing originality ensures sustainable success and fosters a trustworthy reputation online.

Can AI-generated content be considered plagiarism-free?

AI-generated content, such as text produced by language models like GPT-3, GPT-4, and Gemini, can be considered plagiarism-free if properly used and cited. However, using AI writing tools like ChatGPT without adequate citation can lead to unintentional plagiarism. It's vital to use an AI content detector to ensure originality. High-quality tools that use advanced detection models, like Quetext’s AI Detector, can help identify AI-generated text, minimizing the risk of false positives and ensuring that submissions are plagiarism-free.

How does AI technology impact plagiarism detection?

AI-generated content and AI-generated text are now common, making AI content detection crucial. Detecting AI technology, including advanced algorithms and language models like ChatGPT-3 and GPT-4, has significantly improved plagiarism detection. Tools like Quetext’s AI detector tool utilize these advanced models to compare submitted text against vast databases, ensuring accurate detection of potential plagiarism and copy written by artificial intelligence or generative ai.

Definition of Plagiarism

But before checking for plagiarism everyone should know, What Is Plagiarism?

“The act of pretension where you take one’s words and make them your own it can include ideas, thoughts, or any material that you can see/hear and make a copy of.”

If we talk in a legalistic manner then taking someone’s copyright and claiming it to be yours is unintentional plagiarism.

Self-Plagiarism

The concept of thinking that, self-plagiarism is only copying some other's paintings or borrowing someone else's unique idea. In my thoughts like "copying" and "borrowing" can cover the seriousness of the offense.

According to the Oxford Dictionary Plagiarism is:

“The practice of taking someone else's work or ideas and passing them off as one's own”

In precise words, plagiarism is an act of fraud. It involves both stealing someone else's artwork and lying approximately it in a while.

To cater to this, we have the Self-Plagiarism Checker at Scribbr. Just upload any document you used and start the check. You can repeat this as often as you like with all your sources. With your Plagiarism Check order, you get a free pass to use the Self-Plagiarism Checker. Simply upload them to your similarity report and let us do the rest!

Your writing stays private. Your submissions to Scribbr are not published in any public database, so no other plagiarism checker (including those used by universities) will see them.

Personalized Writing Help When You Need it

Unintentional plagiarism, grammar mistakes, and uncited sources  can turn what you thought was a good paper into a poor one. When you’re writing a paper the last thing you want is for your message to get lost due to incorrect punctuation or confusing sentence structure. You know that the great ideas in your head would make for a standout paper, if only you could get them written clearly on the page. If this struggle sounds familiar, you’re not alone.

Great ideas may be an essential part of high-quality writing, but they’re not the only component. Excellent papers and essays clearly express strong ideas with good grammar, proper punctuation, spot-on spelling, and thorough, careful citations. While this may sound like a lot, your teachers and professors are grading you on your skills as both a writer and a researcher, which means your assignments will require an ethical and attentive approach. Luckily, there is no shortage of available tools to help you along your way.

You could use a plagiarism checker free, though, these tools often lack grammatical support. Given the high stakes and rigorous requirements, the aid of a plagiarism checker without the needed support of a grammar checker could mean the difference between an “A” paper and a “C” or even “D” paper.

Thankfully, the EasyBib Plus plagiarism tool provides all-in-one support to cover all your bases. Our premium essay checker is convenient, easy to use, and includes access to a grammar and spell checker, plus a plagiarism checker. With a single scan, you’ll receive personalized feedback to help identify potentially missing citations and help improve your sentence structure, punctuation, grammar, and more.

Not sure if that noun is spelled correctly, or if the preposition at the end of your sentence is grammatically correct? The EasyBib Plus plagiarism tool is your one-stop shop to help check plagiarism, get grammatical suggestions, correct spelling and punctuation errors, and help create polished papers you can be proud to turn in. And, we haven’t told you the best part yet: you can try our tool free and scan your work for grammar suggestions right now!

A Grammar Check for Peace of Mind

You know that grammar plays a significant role in your assignments. Not only does it factor into your overall grade, but without clear and precise language, your ideas can lose their impact or might even be misunderstood entirely. Still, with so many different parts of speech and rules to learn and apply, it’s not uncommon to get them mixed up and find yourself questioning your knowledge now and again:

Can you use an adverb to modify a noun? (No. You need an adjective for that.)

Well, can you use it to modify a pronoun ? (Still no.)

What do they modify, then? (Almost everything else. Fun, right?)

Ugh. (That was an interjection .)

Does this have to be so difficult? (Nope!)

Scanning your paper with the EasyBib Plus writing tool delivers more than the basic punctuation and spell check functions that come standard in word processing programs. You’ll receive immediate, targeted feedback that can help improve the sentence structure and style of your writing. Not only can this help ensure that you don’t lose points off your grade for grammatical errors such as mismatched verb tense, but it can also help to clarify your meaning and strengthen your arguments by eliminating confusing punctuation and run-on sentences that confuse readers.

Reviewing your work to correct errors and refine the flow of your writing is a critical part of the revision process for novices and novelists alike. Even the most conscientious of wordsmiths might make mistakes, such as using a conjunctive adverb in place of a coordinating conjunction or pairing a plural determiner with an uncountable word. They likely appreciate a subscription-based or free grammar check as much as a beginning writer. That’s why the EasyBib Plus writing tool is designed for all writers, from students who are still learning the fundamentals to published professionals who get paid by the word.

The EasyBib Plus writing tool provides quick, targeted feedback that you can use to help improve your writing immediately. Also, our free resource library is available 24/7, just like the rest of our tools, to help you brush up on the areas that challenge you the most (Conjunctive what? Uncountable who?) That means you can continue to sharpen your skills and improve your writing over time, which will help make finishing your next project easier.

Ready to give your paper a boost? Sign up for EasyBib Plus or scan a paper right now for a free spell check—it’s easy!Just upload or copy and paste your paper to the online grammar check tool and, in a matter of seconds, you’ll be able to receive up to 5 feedback cards so you can begin polishing your draft.

Why is Grammar So Important, Anyway?

Why is grammar important? As long as others know what you mean, does it really matter if you use proper grammar? These are age-old questions, but the answers remain unchanged. Grammar is important for many reasons:

Communication:  Communication is about more than merely listening and talking. We communicate in myriad ways: with our voices, our mannerisms, our facial expressions, our actions, and frequently, our written words. Written communication is just as important as all the other ways we broadcast our thoughts and feelings. Unlike our other communication methods, though, written communication leaves a record. While most of us relax our style when talking to or texting friends, the fact remains that more formal venues require a more formal tone. Proper spelling, grammar, and punctuation are a necessary element of professional and academic writing, so running your work through a spelling and grammar check before you submit it is an absolute must.

Clarity:  Expressing your thoughts, ideas, and opinions is an uphill battle when you communicate them with less-than-stellar punctuation, spelling, and grammar. A missing or misplaced comma, for example, can entirely change your meaning:

• Call me Ishmael = My name is Ishmael.
• Call me, Ishmael = I want Ishmael to call me.

Spelling errors can result in similarly muddled meaning:

• Her shoes perfectly complemented her dress. = Her shoes and dress go well together.
• Her shoes perfectly complimented her dress. = Her shoes can both speak and engage in flattery.

Grammar deficiencies such as a dangling modifier yield similarly confusing results:

• I saw the girl’s purple backpack in the library. = The purple backpack belonging to the girl is in the library; I saw it.
• I saw the purple girl’s backpack in the library. = You know the girl who mysteriously turned purple? I saw her backpack in the library. This week has not been easy on her.

Credibility: Establishing your credibility is critical whether you’re writing for school or business. Proving that you can reliably communicate using proper grammar is essential to establishing and maintaining the trust of your teachers, professors, readers, customers, and colleagues.

What Happens After I Upload My Paper?

Once you upload a paper, the EasyBib Plus grammar checker scans your text and highlights grammar issues within your document so you can see it in context. For users running a grammar check and spell check using the grammar check free tool, up to the first 5 issues are shown. For subscription subscribers, all of the areas that require your review will be highlighted once the scan is complete.

No matter which version of the tool you’re using, your feedback will include detailed explanations so you can understand why the text was flagged. Other highlighted areas will include examples of how the issues can be fixed. Some will include a detailed explanation as to why the issue was flagged. This personalized feedback allows you to make an educated decision about whether to edit your text or dismiss the suggestion, so you’re always in control of your final draft.

Subscription users also have the plagiarism checker at their disposal when scanning their papers for style and grammar suggestions. Just as with our other writing tools, when you use the tool to check plagiarism, changes are never made without your review, so you are always in the driver’s seat. You can review each highlighted area as well as the sources of matching text and will always be given a choice to either accept or ignore both citation and grammar suggestions.

Whether you are a student or a professional, the EasyBib Plus tools are powerful allies that can help you improve your paper, establish credibility as a writer, and maintain an ethical writing process.

Check for Unintentional Plagiarism

Persistent use of the best grammar checker and spell checker you can find will help to shape up the style and substance of your composition. However, to ensure the integrity of your work and root out unintentional instances of academic dishonesty, you’ll also need to incorporate a subscription-based or free plagiarism checker for students.

The ability to scan your paper and check plagiarism and grammar before submitting your work is an invaluable tool for students. It’s so valuable, in fact, that students are not the only ones who consistently use this type of software.

Many teachers and professors use a service to ensure that student papers are original and include properly formatted and sourced citations for all reference materials. For some, this may be a consistent element of their grading process, while others may utilize one only when they feel there is a reason to do so.

What Exactly Does a Plagiarism Checker Do?

If you’ve used an online plagiarism checker before, you may be familiar with the process that these tools employ. For those who have never used one, it can be helpful to understand how these tools work and what you should expect as a result of using one.

The most basic free tools will scan your paper and provide you with a percentage that indicates how much of your work is original. This feature can be useful to a point, as some instructors and institutions set a percentage for the amount of similar text that is considered acceptable. This policy does not mean that they are lenient about academic dishonesty but, instead, that they recognize that similar or even matching word choice is not always an indicator of copying.

However, some schools do not tolerate any form of incremental plagiarism, period. In these institutions, “check paper for plagiarism” is likely a standard action when grading all papers.

With a free plagiarism checker, the percentage of word-for-word plagiarism in your text may be the only feedback you receive. Moreover, some of these providers may wade in unethical waters, and offer essay writing services in conjunction with their checking services. This is why many students and teachers prefer subscription-based checkers that focus on integrity, such as the EasyBib writing tools.

With our premium tools, you get more than just supporting proof that your paper is original and in your own words. Your writing is scanned for potentially matching text and areas that needs your attention is highlighted. We’ll provide you with the source of the matching text so you can review it and decide how to proceed. If you agree that a citation is needed, our citation tools and resources will provide you with the information you need to help format and insert the new sources in your text as well as your works cited page.

How Does the EasyBib Plus Online Plagiarism Checker Work?

The EasyBib Plus writing tool provides an all-in-one spell check, grammar review, and plagiarism checker that not only helps you with the paper you’re writing now but enables you to gain new knowledge and improve your writing for the future, too.

Our essay checker searches online for phrases, sentences, or passages that are similar to those in your paper. If it returns matching text, this may indicate that you have passages that are missing citations.

Just as with many checkers, our tool will tell you how many instances of matching text it finds in your paper. Our plagiarism tool is designed to do more than most free tools, however.

When a portion of your paper is flagged for review, we provide you with the source that it matches. As with our online spell check tool, you have the power to review each area and choose how to proceed. If you decide to cite the flagged text, you can review the suggested source and access our citation tools to help create a proper citation and start building a bibliography for your paper. Or, you may determine that no citation is needed, in which case it’s simple to dismiss the suggestion and continue to the next section.

If you’re unsure about how to proceed, our library of resources can help you learn more and make an educated decision. In this way, you gain more than just the ability to correct your work; over time, you can learn how to avoid plagiarism altogether.

Reasons Your Teacher May Run Your Paper Through a Plagiarism Detector

As stated previously, your teachers and professors grade papers with a fixed process that includes “check paper for plagiarism” as a standard, across-the-board action. Others may check for plagiarism only when they feel there is cause to do so. There are a few red flags that may stand out to them while reviewing a paper that would lead to their running a plagiarism check, including:

Style/Voice:  Most teachers are familiar with the style and voice that you use in your writing. While most will hope that the feedback they provide when grading your work will help you to improve problem areas over time, a paper or essay that has a dramatically different style or voice than the work you’ve previously submitted can be a red flag.

Inconsistency:  Changes in the font, font size, formality, formatting, and more may indicate that portions of a paper have been copied and pasted. If these inconsistent passages are not presented as quotations or don’t include citations, this may further indicate to your teacher that there’s plagiarism in the paper.

Old References:  Part of a well-researched paper is verifying the legitimacy and relevance of your sources. While some older references may be acceptable depending on the topic, if all of your sources are outdated, it may lead your teacher to believe that you’ve recycled your own work or someone else’s.

What is Plagiarism?

If you’re looking for a free online plagiarism checker , you’re already aware that it’s not something you want to be found in your papers. However, you may still be wondering: what does plagiarism mean? It’s a reasonable question and one that merits exploring. After all, some of the actions and circumstances that fall within the plagiarism definition come as a surprise to those who only learn that they’ve committed them after it’s too late.

So what is plagiarism? To define plagiarism in the most basic sense, you might say that it is taking someone else’s ideas and words and passing them off as your own.

If your goal is avoiding plagiarism entirely, you’ll need to go beyond the basics to thoroughly define plagiarism, recognize it, and keep clear of it. Some examples of plagiarism that students find surprising include forgotten citations, poor paraphrasing, and re-submitting your own work in whole or in part for more than one assignment. This useful article provides more help in recognizing and understanding the different forms that academic dishonesty can take.

Of course, using your own words and ideas does not count as plagiarism, nor does using common knowledge . Basically, common knowledge is information that is well known by the average person. Examples of common knowledge:

• there are 12 months in a year
• the freezing point of Celsius is zero degrees
• Socrates was a Greek philosopher

So should you only include your original thoughts and common knowledge in your papers? Of course not! Research-based assignments are meant to demonstrate your skills as a researcher, after all, as well as your ability to build upon the work of others to formulate new ideas. To avoid accidentally committing an act that falls within the plagiarism definition when you’re using another person’s words or ideas, though, you need to give them proper credit. This means you’ll need to clearly identify direct quotations or properly paraphrase them when including them in your paper.

Regardless of your approach, you’ll also need to cite your sources according to the style your professor specifies. Generally, you will use MLA format for the arts and humanities and APA format for the sciences, but it’s always best to check with your instructor when you’re unsure.

If you know what style to use but still aren’t sure how to create your citations, don’t fret! Our library of resources includes free guides to help you learn about various styles so you can properly structure and place them. And our premium tools not only help you check grammar, spelling, and originality in your papers, but subscribers also enjoy access to our citation creation tools!

What are the Different Types of Plagiarism?

In addition to the question “what is plagiarism,” you may also be wondering, “why do students plagiarize?” While some students do intentionally plagiarize because they believe they can pass off someone else’s work as their own to avoid spending time on their assignments, many others do so accidentally. They may not understand how broad the plagiarism definition is or they haven’t learned how to research and cite their sources properly. That is why it is vital to recognize plagiarism in all of its forms if you wish to ensure the integrity of your work.

Examples of plagiarism & How to prevent it

Direct plagiarism:

Intentionally copying another person’s work without including a citation that gives credit to the source. When most students are asked to identify potential plagiarism examples and behaviors, this direct and deliberate act is what they think of first.

• Prevention: If you use an idea or quote from another source, cite it in the text. Make it clear that it was not your own words. 

Incremental plagiarism:

Copying parts of another person’s work, such as phrases, sentences, or paragraphs without crediting the source. When deciding which tools to use to check a paper for plagiarism , instructors often seek out those that will identify incremental forms as well as instances of direct copying and similar phrasing.

• Prevention : Decide to either directly quote the phrases or sentences you want to use, or write a good paraphrase. In both cases, be sure to add a citation. Using a plagiarism checker could also help you identify problematic passages.

Self-plagiarism:

Academic self-plagiarism occurs when a student submits the same paper or parts of a paper for more than one assignment. When your instructors are grading your papers, they’re assessing your research and writing skills in the present. When you submit work that you completed in the past, they are both unable to evaluate your current skills and unaware that you haven’t completed the assignment.

• Prevention: Write a new paper for each assignment you’re assigned. If you feel strongly that your past work could enhance your new paper, speak to your instructor and ask for permission first.

Misleading citations:

Including a citation for a quote or idea that misrepresents the source material. This can occur if a student does not understand the reference they are citing; if a student includes a citation for a disreputable source; or the source material simply does not align with the idea or argument that the student has attributed to it.

• Prevention: Carefully review your assignment to understand it. As you research, take the time to evaluate each source notes . Remember, it’s better to have quality citations over an abundance of citations.

Invented sources:

If a reference in a student’s bibliography is found not to exist, it is considered an invented source. This may occur if a student couldn’t find a reputable source to back their argument, or if they needed to include additional references to meet the requirements of the assignment and chose to take an unethical shortcut rather than completing the required amount of research. No matter the reason, this behavior ultimately hurts them in the long run. Not only will they fail to gain the experience they need to conduct research in the future properly, but they’ll also experience significant consequences if they’re caught.

• Prevention: Set aside time to do proper research so you can find enough sources. Start creating a list of sources as you’re researching and take good notes. This will help you keep track of your sources so none are forgotten. If you do end up forgetting where a quote came from, a paper checker could help you pinpoint the original source. 

Patchwriting/Spinning:

Patchwriting is often confused with paraphrasing, but there’s a significant difference. When you paraphrase, you demonstrate that you understand the topic well enough to restate it in your own words. When you patchwrite or spin, it is more akin to a word-swapping game; there’s no need to understand the subject, merely to have access to a thesaurus so you can substitute enough synonyms to mask the source material. This can be intentional, but it may also be a result of having a poor understanding of how to paraphrase.

• Prevention: Using your own words, write down the key points of the phrase or idea, and put them together in a sentence. Be sure to include a citation as well. 

A good way to test if you’re patchwriting or paraphrasing is to remove your sources from view. If you can write about what you’ve read without looking at the source material, you likely understand it well enough to paraphrase it. If you have to review the source material with each new sentence or consult a thesaurus while writing about it (except when you’re adding direct quotations), you may be spinning your sources instead of paraphrasing them.

Academic Integrity Policies and Statements

If you’re still uncertain about what counts as plagiarism, look for your school’s/ organization’s policies on academic integrity and plagiarism. The policies of academic institutions usually cover what is considered plagiarism, the consequences of committing it, and how to avoid it. One great example is Purdue University’s Academic Integrity statement .

What are the Consequences of Plagiarism?

No matter the setting, plagiarism is not taken lightly, and the consequences can be significant. For a good reason, too! Whether in an academic or professional setting, the plagiarism consequences reflect the seriousness of the act, which is ultimately a form of theft that hurts everyone involved.

Just as with the theft of a tangible object, there can be legal punishments for plagiarism. It is, after all, a form of copyright infringement in many instances. A quick search for plagiarism articles will reveal that professional instances of intellectual theft have resulted in civil lawsuits and can even be criminally prosecuted under rare circumstances. In addition to the possible legal consequences, professionals may lose their jobs or have to start over in a new field after their acts of fraud are uncovered.

As a student, you’re likely to wonder what happens if you plagiarize in college or high school. While there will almost always be consequences for this behavior, there is no one-size-fits-all plagiarism sentence. Depending on the circumstances, academic dishonesty could result in outcomes such as:

• You might get a zero for the assignment in which the infringement occurred.
• You may receive a failing grade for the class. If it is a required course, this could leave you without enough credits to move on to the next level until you can repeat it and, in some instances, postpone graduation.
• You may be expelled from your school or university.

The academic dishonesty may be noted on your transcript, which can lead to you not getting into your preferred college, graduate school, or Ph.D. program in the future.

Nobody wants to be known as a fraud or to have a reputation for dishonesty follow them through their career. And, given the consequences that can extend beyond just their reputation, it’s no wonder that professional and academic writers who wish to avoid them take the time to understand the complete definition of plagiarism and run their work through a plagiarism checker before sending it out into the world.

Even the vigilant can fall prey to inferior tools, unfortunately. Before selecting a plagiarism checker, you should understand how they work and what they can (and cannot) detect.

How We Check for Plagiarism

When exploring how to check for plagiarism, most students and professionals conclude that including a checking tool in their revision process is not only helpful but necessary. When you consider the Herculean task of checking each line of your paper against the text of each of your resources, the benefits of a checker are clear. Moreover, this manual approach would only alert you to matching text in the sources you’re aware of, after all, and leaves the sources you haven’t reviewed untouched.

But, hang on. Why would sources you haven’t reviewed factor into your review? The answer to this lies in the plagiarism definition you learned above. What is plagiarism? It’s presenting someone else’s work or ideas as your own, intentionally or otherwise. It is not uncommon to uncover an idea while you’re researching a topic and later misremember it as your own. This might even occur years after you originally came across it.

You might wonder: how can plagiarism be avoided if you have to account for the source of every thought you include in your work? A few exceptions minimize the scope of this. Common knowledge about your topic does not need to be supported by a citation, nor does knowledge that you gained through your personal experience. Using a subscription-based or free plagiarism checker will help you locate any passages that may fall into these categories so you can review them and decide for yourself whether a citation is needed.

EasyBib Plus writing tools provide easy, convenient, and reliable support to help you find potentially missed citations and can help you improve your paper into a high-quality paper with integrity. Simply upload your paper, select the checker, then sit back and relax as the site scans your document. In mere moments, we’ll search the web for passages of similar text and highlight duplicate content for your review.

Regardless of the tools you use to help you revise and polish your work, it’s ultimately your responsibility to ensure that you’re writing and submitting ethical work. That’s why our tools go beyond the basics and require your participation. The tool never automatically makes changes to your paper, but only flags sections that may need your attention and provides you with the matching source so you can to make an educated decision.

If you find that a citation is needed, our citation tools can help you create properly formatted citations and develop a complete bibliography. And, if you review the passage and determine that the match is coincidental, you can dismiss the alert and move on to the next.

Seamless Citation Creation

Professional writers and students alike can find creating citations incredibly confusing. Nevertheless, they are an integral part of a well-written and researched paper and a requirement in almost all academic settings. But, have you ever wondered why they are so important? Citations really do have a purpose—other than driving us crazy— that make it necessary always to cite our sources.

We cite our sources for a few important reasons:

We need to give credit where credit is due. When you use a quote from someone else’s work, you need to give credit for using their words and ideas. Research is often based on the works and ideas of others. However, to include the words and ideas of another without giving them proper credit is to plagiarize, even if the act was unintentional.

In addition, showing that you’ve done proper research by including in text & parenthetical citations and a comprehensive list of sources to back up your arguments gives your work a layer of credibility that can help you earn the trust of your reader or teacher.

Readers can find the sources you used.  When you’re writing high school or undergraduate papers, your only readers may be your instructors and peers. However, including citations at every level of writing helps to ensure that anyone who reads your work can access your sources to check their accuracy, learn more about your topic, and further their own research.

Sources can take your research and learning to the next level, too. When you are conducting research on a topic, checking the works cited or annotated bibliographies prepared by your sources can lead you down new avenues in your research to further develop your ideas and help you write your papers.

Correctly utilizing citations gives strength to your thoughts and opinions. Understanding the value of citations does not, unfortunately, make them any easier to create. We know how confusing it can be, but don’t throw in the towel on learning how to cite websites in MLA , create your APA citation website references, or format your works cited —this is where we come in!

Re-introducing participation reports to encourage best practices in open metadata.

We’ve just released an update to our participation report, which provides a view for our members into how they are each working towards best practices in open metadata. Prompted by some of the signatories and organizers of the Barcelona Declaration, which Crossref supports, and with the help of our friends at CWTS Leiden, we have fast-tracked the work to include an updated set of metadata best practices in participation reports for our members.

2024 July 22

Metadata schema development plans.

It’s been a while, here’s a metadata update and request for feedback In Spring 2023 we sent out a survey to our community with a goal of assessing what our priorities for metadata development should be - what projects are our community ready to support? Where is the greatest need? What are the roadblocks? The intention was to help prioritize our metadata development work. There’s a lot we want to do, a lot our community needs from us, but we really want to make sure we’re focusing on the projects that will have the most immediate impact for now.

Crossmark community consultation: what did we learn.

In the first half of this year we’ve been talking to our community about post-publication changes and Crossmark. When a piece of research is published it isn’t the end of the journey—it is read, reused, and sometimes modified. That’s why we run Crossmark, as a way to provide notifications of important changes to research made after publication. Readers can see if the research they are looking at has updates by clicking the Crossmark logo.

2024 July 01

Celebrating five years of grant ids: where are we with the crossref grant linking system.

We’re happy to note that this month, we are marking five years since Crossref launched its Grant Linking System. The Grant Linking System (GLS) started life as a joint community effort to create ‘grant identifiers’ and support the needs of funders in the scholarly communications infrastructure. The system includes a funder-designed metadata schema and a unique link for each award which enables connections with millions of research outputs, better reporting on the research and outcomes of funding, and a contribution to open science infrastructure.

• Find a service >

A service provided by Crossref and powered by iThenticate—Similarity Check provides editors with a user-friendly tool to help detect plagiarism.

Our Similarity Check service helps Crossref members prevent scholarly and professional plagiarism by providing immediate feedback regarding a manuscript’s similarity to other published academic and general web content, through reduced-rate access to the iThenticate text comparison software from Turnitin.

Only Similarity Check members benefit from this tailored iThenticate experience that includes read-only access to the full text of articles in the Similarity Check database for comparison purposes, discounted checking fees, and unlimited user accounts per organization.

Watch the introductory Similarity Check animation in your language:

With editors under increased pressure to assess higher volumes of manuscript submissions each year, it’s important to find a fast, cost-effective solution that can be embedded into your publishing workflows. Similarity Check allows editors to upload a paper, and instantly produces a report highlighting potential matches and indicating if and how the paper overlaps with other work. This report enables editors to assess the originality of the work before they publish it, providing confidence for publishers and authors, and evidence of trust for readers. And as the iThenticate database contains over 78 million full-text scholarly content items, editors can be confident that Similarity Check will provide a comprehensive and reliable addition to their workflow.

Making sure only original research is published provides:

• peace of mind for publishers and authors that their content is identified and protected,
• a way for editors to educate their authors and ensure the reputation of their publication, and
• clarity for readers around who produced the work.

Benefits of Similarity Check

Similarity Check participants enjoy use of iThenticate at reduced cost because they contribute their own published content into Turnitin’s database of full-text literature. This means that as the number of participants grows, so too does the size of the database powering the service. More content in the database means greater peace of mind for editors looking to determine a manuscript’s originality.

If you participate in Similarity Check, not only do you get reduced rate access to iThenticate, but you also have the peace of mind of knowing that any similarity between your published content and manuscripts checked by other publishers will be flagged as a potential issue too.

As a Similarity Check user, you also see extra features in iThenticate, such as enhanced text-matches within the Document Viewer.

How the Similarity Check service works

To participate in Similarity Check, you need to be a member. Similarity Check subscribers allow Turnitin to index their full catalogue of current and archival published content into the iThenticate database. This means that the service is only available to members who are actively publishing DOI-assigned content and including in their metadata full-text URLs specifically for Similarity Check.

Turnitin indexes members’ content directly via its Content Intake System (CIS). Its CIS accesses our metadata daily to collect the full-text content links provided by our members within their metadata. Turnitin follows these URLs and indexes the content found at each location.

When you apply for the Similarity Check service, Turnitin will check that they can access your existing content via the full-text URLs in your Crossref metadata. Once confirmed, you’ll be provided with access to the iThenticate tool where you will be able to submit manuscripts to compare against the corpus of published academic and general web content in Turnitin’s database. You can do this in the iThenticate tool, or through your manuscript submission system using an API. iThenticate provides a Similarity Report containing a Similarity Score and a highlighted set of matches to similar text. Editors can then further review matches in order to make their own decision regarding a manuscript’s originality.

Download the Similarity Check factsheet , and explore factsheets for other Crossref services and in different languages .

Fees for Similarity Check

Similarity Check fees are in two parts: an annual service fee, and a per-document checking fee.

The annual service fee is 20% of your Crossref annual membership fee and is included in the renewal invoices you receive each January. When you first join Similarity Check, you’ll receive a prorated invoice for the remainder of that calendar year.

Per-document checking fees are also paid annually in January. Volume discounts apply, and your first 100 documents are free of charge.
