Plagiarism: What It is and How to Recognize and Avoid It
What is Plagiarism and Why is it Important?
In college courses, we continually engage with other people's ideas: we read them in texts, hear them in lecture, discuss them in class, and incorporate them into our own writing. As a result, it is very important that we give credit where it is due. Plagiarism is using others' ideas and words without clearly acknowledging the source of that information.
How Can I Avoid Plagiarism?
To avoid plagiarism, you must give credit whenever you use
- another person's idea, opinion, or theory;
- any facts, statistics, graphs, drawings—any pieces of information—that are not common knowledge;
- quotations of another person's actual spoken or written words; or
- paraphrase of another person's spoken or written words.
These guidelines are taken from the Code of Student Rights, Responsibilities, and Conduct.

How to Recognize Unacceptable and Acceptable Paraphrases
Here's the ORIGINAL text, from page 1 of Lizzie Borden: A Case Book of Family and Crime in the 1890s by Joyce Williams et al.:
The rise of industry, the growth of cities, and the expansion of the population were the three great developments of late nineteenth century American history. As new, larger, steam-powered factories became a feature of the American landscape in the East, they transformed farm hands into industrial laborers, and provided jobs for a rising tide of immigrants. With industry came urbanization the growth of large cities (like Fall River, Massachusetts, where the Bordens lived) which became the centers of production as well as of commerce and trade.
Here's an UNACCEPTABLE paraphrase that is plagiarism:
The increase of industry, the growth of cities, and the explosion of the population were three large factors of nineteenth century America. As steam-driven companies became more visible in the eastern part of the country, they changed farm hands into factory workers and provided jobs for the large wave of immigrants. With industry came the growth of large cities like Fall River where the Bordens lived which turned into centers of commerce and trade as well as production.
What makes this passage plagiarism?
The preceding passage is considered plagiarism for two reasons:
- the writer has only changed around a few words and phrases or changed the order of the original's sentences.
- the writer has failed to cite a source for any of the ideas or facts.
If you do either or both of these things, you are plagiarizing.
NOTE: This paragraph is also problematic because it changes the sense of several sentences (for example, "steam-driven companies" in sentence two misses the original's emphasis on factories).
Here's an ACCEPTABLE paraphrase:
Fall River, where the Borden family lived, was typical of northeastern industrial cities of the nineteenth century. Steam-powered production had shifted labor from agriculture to manufacturing, and as immigrants arrived in the US, they found work in these new factories. As a result, populations grew, and large urban areas arose. Fall River was one of these manufacturing and commercial centers (Williams 1).
Why is this passage acceptable?
This is acceptable paraphrasing because:
- the writer accurately relays the information in the original.
- the writer uses their own words.
- the writer lets the reader know the source of their information.
Here's an example of quotation and paraphrase used together, which is also ACCEPTABLE:
Fall River, where the Borden family lived, was typical of northeastern industrial cities of the nineteenth century. As steam-powered production shifted labor from agriculture to manufacturing, the demand for workers "transformed farm hands into industrial laborers," and created jobs for immigrants. In turn, growing populations increased the size of urban areas. Fall River was one of these hubs "which became the centers of production as well as of commerce and trade" (Williams 1).
Why is this passage acceptable?
This is acceptable paraphrasing because:
- the writer records the information in the original passage accurately.
- the writer gives credit for the ideas in this passage.
- the writer indicates which part is taken directly from the source by putting the passage in quotation marks and citing the page number.
Note that if the writer had used these phrases or sentences in their own paper without putting quotation marks around them, they would be PLAGIARIZING. Using another person's phrases or sentences without putting quotation marks around them is considered plagiarism EVEN IF THE WRITER CITES IN THEIR OWN TEXT THE SOURCE OF THE PHRASES OR SENTENCES THEY HAVE QUOTED.
Plagiarism and the Internet
Because of the enormous amount of information available on the internet, you may have questions about how to avoid plagiarizing these sources. In most cases, the same rules apply as to a printed source: when a writer must refer to ideas or quote from a website, they must cite that source.
If a writer wants to use visual information from a website, many of the same rules apply. Copying visual information or graphics from a website (or from a printed source) is very similar to quoting information, and the source of the visual information or graphic must be cited. The same is true for other online media such as podcasts, blogs, online news outlets, YouTube, and e-books. These rules also apply to other uses of textual or visual information from websites; for example, if students are constructing a web page as a class project, and copy graphics or visual information from other sites, they must also provide information about the source of this information. In that case, it might be a good idea to obtain permission from the site's owner before using the graphics.
Strategies for Avoiding Plagiarism
1. Put in quotations everything that comes directly from the text, especially when taking notes.
2. Paraphrase, but be sure you are not just rearranging or replacing a few words.
Instead, read over what you want to paraphrase carefully; cover up the text with your hand, or close the text so you can't see any of it (and so aren't tempted to use the text as a "guide"). Write out the idea in your own words without peeking.
3. Check your paraphrase against the original text to be sure you have not accidentally used the same phrases or words, and that the information is accurate.
Terms You Need to Know (or What is Common Knowledge?)
Common knowledge: facts that can be found in numerous places and are likely to be known by a lot of people.
Example: John F. Kennedy was elected President of the United States in 1960.
This is generally known information. You do not need to document this fact.
However, you must document facts that are not generally known and ideas that interpret facts.
Example: According to the American Family Leave Coalition's new book, Family Issues and Congress, President Bush's relationship with Congress has hindered family leave legislation (6).
The idea that "Bush's relationship with Congress has hindered family leave legislation" is not a fact but an interpretation; consequently, you need to cite your source.
Quotation: using someone's words. When you quote, place the passage you are using in quotation marks, and document the source according to a standard documentation style.
The following example uses the Modern Language Association's style:
Example: According to Peter S. Pritchard in USA Today, "Public schools need reform but they're irreplaceable in teaching all the nation's young" (14).
Paraphrase: using someone's ideas, but putting them in your own words. This is probably the skill you will use most when incorporating sources into your writing. Although you use your own words to paraphrase, you must still acknowledge the source of the information.
