When you reproduce an author's exact wording and phrasing, you must place the text within quotation marks or set off the text in block quotes or other formats recommended in various style manuals. Even if you re-word the material in your own terms, a practice called "paraphrasing," you must credit the source of the information.
You can find guidelines for quotation practice in many style manuals or guides for researchers. A useful introduction can be found in chapter 12 of The Modern Researcher by Jacques Barzun and Henry Graff (5th ed., 1992).
Plagiarism is defined as "offering as one’s own work the words, ideas, or arguments of another person without appropriate attribution by quotation, reference or footnote.”
The consequences of plagiarizing another's work can be very serious for one's course grade or for one's entire academic career. Plagiarism and academic dishonesty go beyond simply cutting and pasting text from an article or book into your paper without attribution; they can include paraphrasing without attribution or even citing sources that you have not consulted in your Works Cited list.
Citing your sources is the first step to avoiding plagiarism.
When you use other authors' ideas and words in your own writing, it is important to credit them - even if you do not quote their words exactly as written. Citing your sources allows your reader to identify the works you have consulted and to understand the breadth and scope of your research. Footnotes, endnotes, and lists of works consulted provide substantiation for your own findings and ideas.
Practicing "cite as you write" and keeping track of ideas and quotations that you use in your own writing helps you to avoid plagiarism or charges of research misconduct.
There are hundreds of citation styles. Your instructor, department, college, or editor may recommend that you use a particular style—or they may ask that you simply be consistent. Four of the most commonly-used citation styles in academic writing are:
Citation managers are software programs or browser tools that allow you to collect and organize citations to books, articles, or other materials that you have used in your research. These tools make it easy to "cite while you write" by allowing you to insert citations into your writing in hundreds--even thousands--of different styles.
