ENG 101: English as a Second Language for International Students (Blumenthal): Why Citation Matters

Reasons to Cite Sources

  • Give credit to the sources where you found your information
  • Help your reader to find your sources
  • Avoid plagiarism:

“Plagiarism is the use of another’s work, words, or ideas without attribution.” (Yale Center for Teaching and Learning)

When to Cite Sources

It is necessary to cite your sources in the following situations:

  1. When you are quoting directly from another source.  Example:

    According to Hydock, Wilson, and Easwar, giving consumers "easier to comprehend and more accurate information on all foods served in all contexts could reduce overeating" (76).

  2. When you paraphrase or summarize an idea that you read in another source. Example:

    According to Hydock, Wilson, and Easwar, giving consumers clear and correct information about their food may prevent overeating (76). | 503.943.7111 or 800.841.8261 | 5000 N. Willamette Blvd., Portland, OR 97203-5798
