| Using something word-for-word from another source? |
Put quotation marks around the excerpt, use a signal phrase, and include a parenthetical citation with the page number: McGuffin and Cross have said, “No one should ever eat cake without frosting” (22). Or Cake, according to McGuffin and Cross, is one of those foods that should never be eaten “without frosting” (22). |
| Using something word-for-word from another source but changing word forms or adding words to improve clarity and flow? |
Put quotation marks around the excerpt, and put brackets around the segments you have changed. Include a signal phrase and a parenthetical citation with the page number: McGuffin and Cross seem to think that “…eat[ing] cake without frosting” should never be allowed (22). |
| Paraphrasing or summarizing the author’s ideas without using the author’s exact words? |
Use a signal phrase and include a parenthetical citation with the page number: According to McGuffin and Cross, cake is one of those special foods that require an additive to be properly enjoyed, like frosting (22). |
| Using something from a source but substituting in some synonyms? |
DON’T. This is plagiarism, even if you use a signal phrase and include a parenthetical citation.
