The Council of Writing Program Administrators defines plagiarism in an instructional context as "occur[ing] when a writer deliberately uses someone else’s language, ideas, or other original (not common-knowledge) material without acknowledging its source. This definition applies to texts published in print or on-line, to manuscripts, and to the work of other student writers." Plagiarism and citing sources incorrectly are two different situations. If writers make every effort to cite sources accurately but do not cite adequately or do not use the correct citation style, they are not plagiarizing. Plagiarism occurs when a writer intentionally takes credit for someone else's ideas or words.
