Many people think of plagiarism as copying another’s work, or borrowing someone else’s original ideas. But terms like “copying” and “borrowing” can disguise the seriousness of the offense:
inventions. Almost all forms of expression fall under copyright protection
as long as they are recorded in some media (such as a book or a computer file).
All of the following are considered plagiarism:
turning in someone else’s work as your own
copying words or ideas from someone else without giving credit
failing to put a quotation in quotation marks
giving incorrect information about the source of a quotation
changing words but copying the sentence structure of a source without giving credit
copying so many words or ideas from a source that it makes up the majority of your work, whether you give credit or not (see our section on “fair use” rules)
Attention! Changing the words of an original source is not sufficient to prevent plagiarism. If you have retained the essential idea of an original source, and have not cited it, then no matter how drastically you may have altered its context or presentation, you have still plagiarized
Most cases of plagiarism can be avoided, however, by
citing sources. Simply acknowledging that certain material has been borrowed, and providing your audience with the information necessary to find that source, is usually enough to prevent plagiarism.
FAQ
What is plagiarism?
Simply put, plagiarism is the use of another's original words or ideas as though they were your own. Any time you borrow from an original source
and do not give proper credit, you have committed plagiarism and violated U.S. copyright laws. (See our
What is Plagiarism? page for more detailed information on plagiarism.)
What are copyright laws?
Copyright laws exist to protect our intellectual property. They make it illegal to reproduce someone else’s expression of ideas or information without permission. This can include music, images, written words, video, and a variety of other media.
At one time, a work was only protected by copyright if it included a copyright trademark (the symbol). According to laws established in 1989, however, works are now copyright protected with
or without the inclusion of this symbol.
Anyone who reproduces copyrighted material improperly can be prosecuted in a court of law. It does not matter if the form or content of the original has been altered – as long as any material can be shown to be substantially similar to the original, it may be considered a violation of the
Copyright Act.
For information on how long a copyright lasts,
see the section below on the public domain.
Are all published works copyrighted?
Actually, no. The Copyright Act only protects works that express original ideas or information. For example, you could borrow liberally from the following without fear of plagiarism:
Compilations of readily available information, such as the phone book
Works published by the U.S. government
Facts that are not the result of original research (such as the fact that there are fifty U.S. states, or that carrots contain Vitamin A)
Works in the public domain (provided you cite properly)
Can facts be copyrighted?
Yes, in some situations. Any “facts” that have been published as the result of individual research are considered the intellectual property of the author.
Do I have to cite sources for every fact I use?
No. You do not have to cite sources for facts that are not the result of unique individual research. Facts that are readily available from numerous sources and generally known to the public are considered “common knowledge,” and are not protected by copyright laws. You can use these facts liberally in your paper without citing authors. If you are unsure whether or not a fact is common knowledge, you should probably cite your source just to be safe.
Does it matter how much was copied?
Not in determining whether or not plagiarism is a crime. If even the smallest part of a work is found to have been plagiarized, it is still considered
a copyright violation, and its producer can be brought to trial. However, the amount that was copied probably will have a bearing on the severity of the sentence. A work that is almost entirely plagiarized will almost certainly incur greater penalties than a work that only includes a small amount of plagiarized material.
But can’t I use material if I cite the source?
You are allowed to borrow ideas or phrases from other sources provided you cite them properly and your usage is consistent with the guidelines set by fair use laws. As a rule, however, you should be careful about borrowing too liberally – if the case can be made that your work consists predominantly of someone else’s words or ideas, you may still be susceptible to charges of plagiarism.
What are the punishments for plagiarism?
As with any wrongdoing, the degree of intent (see below) and the nature of the offense determine its status. When plagiarism takes place in an academic setting, it is most often handled by the individual instructors and the academic institution involved. If, however,
the plagiarism involves money, prizes, or job placement, it constitutes a crime punishable in court.
