Taking Notes, Quoting, Paraphrasing, and Avoiding Plagiarism

Working with sources requires three distinct tools, and mixing them up carelessly is the most common cause of accidental plagiarism. A direct quotation reproduces a source's exact words, marked with quotation marks and cited. A paraphrase restates a source's specific idea in your own words and sentence structure, still cited, because the idea itself still belongs to its original source even when the words do not. A summary condenses a larger passage or an entire source's main point into a much shorter statement, also cited. Plagiarism is presenting any of these, especially a paraphrase close enough in wording or structure to the original, as though it were your own idea or your own sentence construction, without credit.

The most common accidental plagiarism happens during note-taking, not during final drafting: a student copies a source's sentence directly into notes without quotation marks, intending to paraphrase it later, then forgets which words were the source's and which were their own by the time they draft. The fix is a disciplined habit, not a talent: mark every direct quotation with quotation marks the moment you write it down, note the source and page or paragraph number immediately, and when you do paraphrase, close the source and write the idea in your own words entirely from memory, checking back afterward only to verify accuracy, not to copy phrasing.
