"The purpose of a research paper is to synthesize previous research and scholarship with your ideas on the subject. Therefore, you should feel free to use other persons' words, facts, and thoughts in your research paper, but the material you borrow must not be presented as if it were your own creation. When you write your research paper, remember that you must document everything that you borrow--not only direct quotations and paraphrases but also information and ideas."
