CampusGuides: Citing Sources: How to Avoid Plagiarism

What is Plagiarism?

"Plagiarism is using others' ideas and words without clearly acknowledging the source of that information." - from Plagiarism: What It Is and How to Recognize and Avoid It.

Important Terms to Know:

Terminology and Definitions
Citation	Information which identifies a source of information; a citation usually includes the name of the author, the title, and publication information, such as date, page numbers, etc.
	Example: Fisher, Robert E. Buddhist Art and Architecture. Thames and Hudson, 2002.
Citing a Source	"To refer to, as an authority or example," from American Heritage College Dictionary.
	Example: This definition came from the source titled American Heritage College Dictionary which is an authoritative source for definitions.
Common Knowledge (does not require citation)	Facts that can be found in many sources and are likely to be known by most people. No one put any effort into creating this information.
	Example: Abraham Lincoln was assassinated by John Wilkes Booth, a well-known actor, on April, 14, 1865.

Documenting a Source	To identify and support statements in your writing with citations.
	Example: If you use information from the book above (Buddhist Art and Architecture), you must include the citation for it (above) in your Works Cited List or Bibliography.
	The following requires a citation.
Paraphrase	A restatement of speech or writing that retains the basic meaning while changing the words and/or sentence structure of the original. A paraphrase often clarifies the original statement by putting it into words that are more easily understood by the reader. A paraphrase is often longer than the original excerpt.
	See examples under How to Recognize and Avoid Plagiarism below.

Quote	To copy or repeat the exact words of another. In writing, quotations must be identified by quotation marks and an acknowledgement of the source of the quote. When quoting, you must keep the text exactly the same as the original.

Summarize	To condense the substance of a larger work. A summary is usually shorter than a a paraphrase and captures the "gist" of the original statement.

How to Recognize and Avoid Plagiarism

How to Recognize and Avoid Plagiarism: Paraphrasing

Original Text (from The Pursuit of Oblivion: A Global History of Narcotics by Richard Davenport-Hines, 2002).	The prohibition policies of the USA have escalated into the global Wars on Drugs associated since 1969 with the Nixon, Reagan and Bush administrations. The American approach can be summarised as requiring unconditional surrender from traffickers, dealers, addicts and occasional recreational users.
Plagiarism (Unacceptable Paraphrase)	The prohibitive policies in the United States have become the worldwide Wars on Drugs associated since 1969 with the Nixon, Reagan and Bush administrations. The American way of dealing with things can be summarised as requiring complete surrender from dealers, addicts, traffickers and occasional recreational drug users.
	Why is it plagiarism?	Only a few words were changed or the order of words was altered. The source of the text is not cited.
Acceptable Paraphrase	Drug policies in the United States emphasize prohibition at all levels: traffickers, dealers, addicts and occasional recreational users. Although these policies originated in the US, particularly with Republican administrations of the last 30 years, they have grown into the "global Wars on Drugs" (Davenport-Hines 15).
	Why is it acceptable?	The passage was rewritten in the writer's own words while maintaining the meaning of the original text. The source of the text is cited.
Note: You can use paraphrase and quotations together. This is particularly useful for phrases which you don't wish to reword because that would alter the meaning.

How to Recognize and Avoid Plagiarism: Quoting

Original Text (from Becoming Evil: How Ordinary People Commit Genocide and Mass Killing by James Waller, 2002).	In 1492, it is estimated that well over 100 million indigenous people inhabited the Western hemisphere. Two centuries later, it is estimated that the indigenous population of the Americas had been diminished by some 90 percent and was continuing to fall steadily.
Unacceptable Quote	"In 1492, it is estimated that well over 100 million indigenous people inhabited the Western hemisphere. Two centuries later the population of the Americas had been diminished by 90 percent."
	Why is it plagiarism?	The passage has not been quoted accurately. The source of the quotation is not cited.
Acceptable quotation	Although it is thought that there were more than 100 million native inhabitants in the Western hemisphere in 1492,"two centuries later, it is estimated that the indigenous population of the Americas had been diminished by some 90 percent and was continuing to fall steadily." (Waller, 37)
	Why is it acceptable?	The first part of the sentence is an acceptable paraphrase. The second part of the sentence is quoted accurately. The whole passage is cited.

Avoiding Plagarism

Avoid plagiarism by developing good research methods and following some basic rules of writing and documentation.

As you research:

Keep track of the sources you use.

Accurately record the author, title, publisher, date, including the page numbers from which your notes were taken. You will need this information to document your source correctly.

In your notes be careful to make the distinction between your own ideas and the ideas of others. If you copy exact quotations from the text, make it clear in your notes that it is a quotation, either by the use of quotation marks, or highlighting, or a big "Q" in the margin.

As you write:
When paraphrasing, read over the material that you want to paraphrase; then close the source. Without looking back at the original, write out the idea in your own words. Next, check your version against the original for accuracy and mistakenly borrowed phrases.
When paraphrasing, consider beginning your statement by giving credit to the author of your source. Example: According to the historian, Lynn Hunt, . . .

When quoting, you can mention the author's name at the beginning or at the end of the quote.
If there is a word or phrase used by an author that you think is unique and essential to the meaning of the source, put it in quotations and cite it.

As you proofread:

Be certain that you have accurately and completely documented all material from other sources.

Check direct quotations against the original source to be sure that they are accurate.

Double check paraphrased material to make sure that your words and sentence structure are different than the original source.
