    The ease of saving images off of the web has caused a very real problem for artists and content providers alike. If you have placed your intellectual property on the web chances are that sooner or later someone is going to ‘borrow’ a little bit of it… without your permission.” —Linda Cole


    In order to avoid inadvertent plagiarism or academic dishonesty, you must understand intellectual property and copyright. In our digital age, where users can easily download information, we must consider these issues from an ethical perspective as well.

    Intellectual Property (IP) refers to a document or ideas owned by authors, publishers, and corporations. IP is anything that reflects an original thought that is written down or expressed in any media, such as word-processed documents, emails, Web sites, and music. Simply put, what you create is your “intellectual property.” Graphics, songs, poems, pictures, and essays are examples of “properties” that are owned by their creators, properties that are subject to the U.S. and international copyright laws.



    Copyright refers to the laws that protect your ownership of property (whether or not you file a formal copyright application). Plagiarism refers to the theft of someone’s intellectual property. According to the U.S. Copyright Office, Copyright is a form of protection provided by the laws of the United States (title 17, U.S.Code) to the authors of “original works of authorship” including literary, dramatic, musical, artistic, and certain other intellectual works (U.S. Copyright Office, Copyright Basics, Circular 1).

    Copyright refers to the laws that protect the creator’s intellectual property. Copyright laws allow you (as the creator) certain rights. With Copyright, you can do the following:

    1. Reproduce the work in copies such as books or CDs.
    2. Prepare a derivative work. For example, if you write a book or short story, only you can create a play or movie from that story. (Of course, you can sell these rights if you so desire.)
    3. Distribute copies of your work to the public by sales or other methods. You get to perform or display the work publicly (e.g., plays, music, or dance performances).

    There are few intellectual offenses more serious than plagiarism in academic and professional contexts. This resource offers advice on how to avoid plagiarism in your work.

    Contributors: Karl Strolley, Allen Brizee, Joshua M. Paiz

    Research-based writing in American institutions, both educational and corporate, is filled with rules that writers, particularly beginners, aren't aware of or don't know how to follow. Many of these rules have to do with research and proper citation. Gaining familiarity with these rules, however, is critically important, as inadvertent mistakes can lead to charges of plagiarism, which is the uncredited use (both intentional and unintentional) of somebody else's words or ideas.

    While some rhetorical traditions may not insist so heavily on documenting sources of words, ideas, images, sounds, etc., American academic rhetorical tradition does. A charge of plagiarism can have severe consequences, including expulsion from a university or loss of a job, not to mention a writer's loss of credibility and professional standing. This resource, which does not reflect any official university policy, is designed to help you develop strategies for knowing how to avoid accidental plagiarism. For instructors seeking a key statement on definitions and avoidance on plagiarism, see Defining and Avoiding Plagiarism: The WPA Statement on Best Practices.

    (Purdue University students will want to make sure that they are familiar with Purdue's official academic dishonesty policy as well as any additional policies that their instructors have implemented.)


    There are some intellectual challenges that all students are faced with when writing. Sometimes these challenges can almost seem like contradictions, particularly when addressing them within a single paper. For example, American teachers often instruct students to:

    Develop a topic based on what has already been said and written


    Write something new and original

    Rely on experts' and authorities' opinions


    Improve upon and/or disagree with those same opinions

    Give credit to previous researchers


    Make your own significant contribution

    Improve your English to fit into a discourse community by building upon what you hear and read


    Use your own words and your own voice

    There are some actions that can almost unquestionably be labeled plagiarism. Some of these include buying, stealing, or borrowing a paper (including, of course, copying an entire paper or article from the Web); hiring someone to write your paper for you; and copying large sections of text from a source without quotation marks or proper citation.

    But then there are actions that are usually in more of a gray area. Some of these include using the words of a source too closely when paraphrasing (where quotation marks should have been used) or building on someone's ideas without citing their spoken or written work. Sometimes teachers suspecting students of plagiarism will consider the students' intent, and whether it appeared the student was deliberately trying to make ideas of others appear to be his or her own.

    However, other teachers and administrators may not distinguish between deliberate and accidental plagiarism. So let's look at some strategies for avoiding even suspicion of plagiarism in the first place.


    The key to avoiding plagiarism is to make sure you give credit where it is due. This may be credit for something somebody said, wrote, emailed, drew, or implied. Many professional organizations, including the Modern Language Association (MLA) and the American Psychological Association (APA), have lengthy guidelines for citing sources. However, students are often so busy trying to learn the rules of MLA format and style or APA format and style that they sometimes forget exactly what needs to be credited. Here, then, is a brief list of what needs to be credited or documented:

    • Words or ideas presented in a magazine, book, newspaper, song, TV program, movie, Web page, computer program, letter, advertisement, or any other medium
    • Information you gain through interviewing or conversing with another person, face to face, over the phone, or in writing
    • When you copy the exact words or a unique phrase
    • When you are using "common knowledge," things like folklore, common sense observations, myths, urban legends, and historical events (but not historical documents)
    • When you are using generally-accepted facts, e.g., pollution is bad for the environment, including facts that are accepted within particular discourse communities, e.g., in the field of composition studies, "writing is a process" is a generally-accepted fact.


    Generally speaking, you can regard something as common knowledge if you find the same information undocumented in at least five credible sources. Additionally, it might be common knowledge if you think the information you're presenting is something your readers will already know or something that a person could easily find in general reference sources. But when in doubt, cite; if the citation turns out to be unnecessary, your teacher or editor will tell you.


    Most students, of course, don't intend to plagiarize. In fact, most realize that citing sources actually builds their credibility for an audience and even helps writers to better grasp information relevant to a topic or course of study. Mistakes in citation and crediting can still happen, so here are certain practices that can help you not only avoid plagiarism but even improve the efficiency and organization of your research and writing.



    • In your notes, always mark someone else's words with a big Q, for a quote, or use big quotation marks
    • Indicate in your notes which ideas are taken from sources with a big S, and which are your own insights (ME)
    • When information comes from sources, record relevant documentation in your notes (book and article titles; URLs on the Web)


    • Take lots of thorough notes; if you have any of your own thoughts as you're interviewing, mark them clearly
    • If your subject will allow you to record the conversation or interview (and you have proper clearance to do so through an Institutional Review Board, or IRB), place your recording device in an optimal location between you and the speaker so you can hear clearly when you review the recordings. Test your equipment, and bring plenty of backup batteries and media.
    • If you're interviewing via email, retain copies of the interview subject's emails as well as the ones you send in reply
    • Make any additional, clarifying notes immediately after the interview has concluded


    • Use a statement that credits the source somewhere in the paraphrase or summary, e.g., According to Jonathan Kozol, ...).
    • If you're having trouble summarizing, try writing your paraphrase or summary of a text without looking at the original, relying only on your memory and notes
    • Check your paraphrase or summary against the original text; correct any errors in content accuracy, and be sure to use quotation marks to set off any exact phrases from the original text
    • Check your paraphrase or summary against sentence and paragraph structure, as copying those is also considered plagiarism.
    • Put quotation marks around any unique words or phrases that you cannot or do not want to change: e.g., "savage inequalities" exist throughout our educational system (Kozol).


    • Keep the source author's name in the same sentence as the quote
    • Mark the quote with quotation marks, or set it off from your text in its own block, per the style guide your paper follows
    • Quote no more material than is necessary; if a short phrase from a source will suffice, don't quote an entire paragraph
    • To shorten quotes by removing extra information, use ellipsis points (...) to indicate omitted text, keeping in mind that:
      • In longer quotes where you have omitted a sentence in between other complete sentences, maintain terminal punctuation in between the ellipses.
      • Example: "None of the national reports I saw made even passing references to inequality or segregation. . . . Booker T. Washington was cited with increasing frequency, Du Bois never, and Martin Luther King only with cautious selectivity." (Kozol 3).
    • To give context to a quote or otherwise add wording to it, place added words in brackets, ( [] ); be careful not to editorialize or make any additions that skew the original meaning of the quote—do that in your main text, e.g.,
      • OK: Kozol claims there are "savage inequalities" in our educational system, which is obvious.
      • WRONG: Kozol claims there are "[obvious] savage inequalities" in our educational system.
    • Use quotes that will have the most rhetorical, argumentative impact in your paper; too many direct quotes from sources may weaken your credibility, as though you have nothing to say yourself, and will certainly interfere with your style


    • Note the name of the idea's originator in the sentence or throughout a paragraph about the idea
    • Use parenthetical citations, footnotes, or endnotes to refer readers to additional sources about the idea, as necessary
    • Be sure to use quotation marks around key phrases or words that the idea's originator used to describe the idea


    Sometimes innocent, hard-working students are accused of plagiarism because a dishonest student steals their work. This can happen in all kinds of ways, from a roommate copying files off of your computer, to someone finding files on a disk or on a pen drive left in a computer lab. Here are some practices to keep your own intellectual property safe:

    • Do not save your paper in the same file over and over again; use a numbering system and the Save As... function; E.g., you might have research_paper001.doc, research_paper002.doc, research_paper003.doc as you progress. Do the same thing for any HTML files you're writing for the Web. Having multiple draft versions may help prove that the work is yours (assuming you are being ethical in how you cite ideas in your work!).
    • Maintain copies of your drafts in numerous media, and different secure locations when possible; don't just rely on your hard drive, pen drive, or the cloud.
    • Password-protect your computer; if you have to leave a computer lab for a quick bathroom break, hold down the Windows key and L to lock your computer without logging out.
    • Password-protect your files; this is possible in all sorts of programs, from Adobe Acrobat to Microsoft word (just be sure not to forget the password!).


    • Proofread and cross-check with your notes and sources to make sure that anything coming from an outside source is acknowledged in some combination of the following ways:
      • In-text citation, otherwise known as parenthetical citation
      • Footnotes or endnotes
      • Bibliography, References, or Works Cited pages
      • Quotation marks around short quotes; longer quotes set off by themselves, as prescribed by a research and citation style guide
      • Indirect quotations: citing a source that cites another source
      • If you have any questions about citation, ask your instructor well in advance of your paper's due date, so if you have to make any adjustments to your citations, you have the time to do them well

    Read over each of the following passages, and respond on your own or as a class as to whether or not it uses citations accurately. If it doesn't, what would you do to improve the passage so it's properly cited?

    1. Last summer, my family and I traveled to Chicago, which was quite different from the rural area I grew up in. We saw the dinosaur Sue at the Field Museum and ate pizza at Gino's East.
    2. Americans want to create a more perfect union; they also want to establish justice, ensure domestic tranquility, provide for the common defense, promote the general welfare, and secure the blessings of liberty for everybody.
    3. I find it ridiculous that 57% of high school students think their teachers assign too much homework.

    Numbers 4, 5, and 6 all refer to the following passage from Martin Luther King's "Letter from the Birmingham Jail":

    You deplore the demonstrations taking place in Birmingham. But your statement, I am sorry to say, fails to express a similar concern for the conditions that brought about the demonstrations. I am sure that none of you would want to rest content with the superficial kind of social analysis that deals merely with effects and does not grapple with underlying causes. It is unfortunate that demonstrations are taking place in Birmingham, but it is even more unfortunate that the city's white power structure left the Negro community with no alternative.

    1. Martin Luther King was certain that nobody would want to be contented with a feigning type of social analysis that concerns itself only with effects and doesn't deal with root causes.
    2. Martin Luther King wrote that the city of Birmingham's "white power structure" left African-Americans there "no alternative" but to demonstrate ("Letter from the Birmingham Jail" para. 5).
    3. In "Letter from the Birmingham Jail," King writes to fellow clergy saying that although they "deplore the demonstrations taking place in Birmingham, your statement fails to express a similar concern for the conditions that brought about the demonstrations."
    4. My friend Kara told me that she loves living so close to the ocean.
    5. Americans are guaranteed the right to freely gather for peaceful meetings.


    Suspecting a student of plagiarism is never pleasant; proving a student has plagiarized is even worse. It's common for teachers to feel offended and hurt when students have acted unethically in their courses. But there are some things you, as a teacher, can do to minimize plagiarism in your classes. Click here for more resources on how to prevent plagiarism in the classroom.


    One can never be too direct in explaining to students what actions can be considered plagiarism in their class. Writing and providing to students a course policy statement that includes a section on plagiarism is an excellent first step. Be sure to include and cite any school policies that might be suspect.

    Here, for example, is a statement that Professor Irwin Weiser of Purdue University has used with his Introductory Composition courses:

    The following statement about honesty and the use of sources is from the Introduction to First-Year Composition Courses:

    When writers use material from other sources, they must acknowledge this source. Not doing so is called plagiarism, which means using without credit the ideas or expressions of another. You are therefore cautioned (1) against using, word for word, without acknowledgment, phrases, sentences, paragraphs, etc., from the printed or manuscript material of others; (2) against using with only slight changes the materials of another; and (3) against using the general plan, the main headings, or a rewritten form of someone else's material. These cautions apply to the work of other students as well as to the published work of professional writers.

    Of course, these cautions also apply to information you find on the Internet, World Wide Web, or other electronic or on-line sources. Since we will be discussing how to acknowledge and cite sources, you should be able to avoid accidentally plagiarizing anyone else's work. If you are in doubt, please ask me, since the consequences for plagiarism are severe. The university policies about plagiarism include penalties ranging from failure of an assignment to expulsion from the university. In this class, anyone who plagiarizes fails the course, and I will probably inform the Office of the Dean of Students of the reason for the failing grade.
