How to Avoid Plagiarism

It's not enough to know why plagiarism is taken so seriously in the academic world or to know how to recognize it. You also need to know how to avoid it.

The simplest cases of plagiarism to avoid are the intentional ones: If you copy a paper from a classmate, buy a paper from the Internet, copy material from a book, article, podcast, video, or website without citing the author, you are plagiarizing. Here's the best advice you'll ever receive about avoiding intentional plagiarism: If you're tempted to borrow someone else's ideas or plagiarize in any way because you're pressed for time, nervous about how you're doing in a class, or confused about the assignment, don't do it . The problems you think you're solving by plagiarizing are really minor compared to the problems you will create for yourself by plagiarizing. In every case, the consequences of plagiarism are much more serious than the consequences of turning in a paper late or turning in a paper you're not satisfied to have written.

The consequences of accidental plagiarism are equally daunting and should be avoided at all costs. As a member of an intellectual community you are expected to respect the ideas of others in the same way that you would respect any other property that didn't belong to you, and this is true whether you plagiarize on purpose or by accident. The best way to make sure you don't plagiarize due to confusion or carelessness is to 1) understand what you're doing when you write a paper and 2) follow a method that is systematic and careful as you do your research . In other words, if you have a clear sense of what question you're trying to answer and what knowledge you're building on, and if you keep careful, clear notes along the way, it's much easier to use sources effectively and responsibly and, most of all, to write a successful paper.

If you have questions about plagiarism at any point in your research or writing process, ask. It's always better to ask questions than it is to wait for an instructor to respond to work that you have turned in for a grade. Once you have turned in your final work, you will be held responsible for misuse of sources.

Keep Track of Your Sources; Save PDFs or Print Electronic Source

While it's easy enough to keep a stack of books or journal articles on your desk where you can easily refer back to them, it's just as important to keep track of electronic sources. When you save a PDF of a journal article, make sure you put it into a folder on your computer where you'll be able to find it. When you consult a website, log the URL in a separate document from the paper you're writing so that you'll be able to return to the website and cite it correctly. You should also print or save to PDF the relevant pages from any websites you use, making sure you note the complete URL and the date on which you printed the material. Because electronic sources aren't stable and websites can disappear without notice, beware of directing your readers to sources that might have disappeared. Check when the website you're using was last updated and update the URLs as you work and once again right before you submit your essay. If an electronic source disappears before you submit your work, you will need to decide whether or not to keep the source in your paper. If you have saved the source and can turn it in with your paper, you should do so. If you have not saved the source, you should consult your instructor about whether or not to use that source in your paper.

Keep Sources in Correct Context

Whenever you consult a source, you should make sure you understand the context, both of the ideas within a source and of the source itself. You should also be careful to consider the context in which a source was written. For example, a book of essays published by an organization with a political bias might not present an issue with adequate complexity for your project. You can learn more about how to understand a source’s context in the Evaluating Sources section of this guide.

The question of context can be more complicated when you're working with Internet sources than with print sources because you may see one article or post as separate from an entire website and use or interpret that page without fully understanding or representing its context. For example, a definition of "communism" taken from a website with a particular political agenda might provide one interpretation of the meaning of the word—but if you neglect to mention the context for that definition, you might use it as though it's unbiased when it isn't. If your web search takes you to a URL that’s part of a larger website, make sure to investigate and take notes on the context of the information you're citing.

Research can often turn out to be more time-consuming than you anticipate. Budget enough time to search for sources, to take notes, and to think about how to use the sources in your essay. Moments of carelessness are more common when you leave your essay until the last minute— and when you are tired or stressed. Honest mistakes can lead to charges of plagiarism just as dishonesty can; be careful when taking notes and when incorporating ideas and language from sources so you always know what language and ideas are yours and what belongs to a source.

Don't Cut and Paste: File and Label Your Sources

Keep your own writing and your sources separate.

Work with either the printed copy of your source(s) or (in the case of online sources) the copy you downloaded—not the online version—as you draft your essay. This precaution not only decreases the risk of plagiarism but also enables you to annotate your sources. Those annotations are an essential step both in understanding the sources and in distinguishing your own ideas from those of the sources.

Keep Your Notes and Your Draft Separate

Paraphrase carefully in your notes; acknowledge your sources explicitly when paraphrasing.

When you want to paraphrase material, it's a good idea first to paste the actual quotation into your notes (not directly into your draft) and then to paraphrase it (still in your notes). Putting the information in your own words will help you make sure that you've thought about what the source is saying and that you have a good reason for using it in your paper. Remember to use some form of notation in your notes to indicate what you've paraphrased and mention the author's name within the material you paraphrase. You should also include all citation information in your notes.

Avoid Reading a Classmate's Paper for Inspiration

If you're in a course that requires peer review or workshops of student drafts, you are going to read your classmates' work and discuss it. This is a productive way of exchanging ideas and getting feedback on your work. If you find, in the course of this work, that you wish to use someone else's idea at some point in your paper (you should never use someone else's idea as your thesis, but there may be times when a classmate's idea would work as a counterargument or other point in your paper), you must credit that person the same way you would credit any other source.

If you find yourself reading someone else's paper because you're stuck on an assignment and don't know how to proceed, you may end up creating a problem for yourself because you might unconsciously copy that person's ideas. When you're stuck, make an appointment with your instructor or go to the Writing Center for advice on how to develop your own ideas.

Don't Save Your Citations for Later

Never paraphrase or quote from a source without immediately adding a citation. You should add citations in your notes, in your response papers, in your drafts, and in your revisions. Without them, it's too easy to lose track of where you got a quotation or an idea and to end up inadvertently taking credit for material that's not your own.

Quote Your Sources Properly

Always use quotation marks for directly quoted material, even for short phrases and key terms.

Keep a Source Trail

As you write and revise your essay, make sure that you keep track of your sources in your notes and in each successive draft of your essay. You should begin this process early, even before you start writing your draft. Even after you've handed in your essay, keep all of your research notes and drafts. You ought to be able to reconstruct the path you took from your sources to your notes and from your notes to your drafts and revision. These careful records and clear boundaries between your writing and your sources will help you avoid plagiarism. And if you are called upon to explain your process to your instructor, you'll be able to retrace the path you took when thinking, researching, and writing, from the essay you submitted back through your drafts and to your sources.
