PERRLA/Turabian 101/Avoiding plagiarism

Writing With Sources and Avoiding Plagiarism

Plagiarism is using someone else's ideas, words, or work without giving them credit, even by accident. Avoid it by quoting, paraphrasing, or summarizing, and giving the source a note every time. Then keep your own argument in the lead, with the sources in support.

Lesson 17 of 18Section 5: The Writing Process

When you write an academic paper, you're building on the ideas of others. That's the foundation of academic writing: joining a larger conversation, and using credible sources to support your points. With that comes a serious responsibility: giving credit where it's due.

Why plagiarism matters

Plagiarism is more than a school rule. It's an ethical violation. When you use someone else's ideas, words, or work without proper credit, you're claiming them as your own. In academic settings, that can mean failing the assignment, failing the course, or even probation or expulsion.

More importantly, plagiarism damages your credibility. Giving proper credit shows that you've done the research, understand the material, and are adding your own thinking to the conversation.

Fortunately, plagiarism is easy to avoid once you know the three ways to use a source: quoting, paraphrasing, and summarizing.

Quoting, paraphrasing, and summarizing

  • Quoting means copying a passage exactly as it appears in the source, with quotation marks around it (or as a block quote, if it runs five or more lines). Use it when the exact wording matters.
  • Paraphrasing means restating the author's idea in your own words and your own sentence structure, without changing the meaning. It shows you understand the idea well enough to explain it.
  • Summarizing is like paraphrasing, but shorter. You boil the main idea of a longer passage down to a brief point.

Whichever you use, the source gets a note. Even when you aren't quoting, the idea still belongs to someone else.

One source, three ways

Here is one finding from a real study, used three ways in the sample Bigfoot paper. The paper already cited the study in full earlier, so these notes are shortened.

  1. A quoteThe authors' exact words in quotation marks, and the page in the note.
  2. A paraphraseThe same finding in new words and a new sentence, still with a note and the page.
  3. A summaryThe main idea in one short line, still with a note. It covers the whole study, so no single page is needed.

Working sources into your writing

  • Use sources to support your point, not to replace it. Your argument and your voice should drive the paper.
  • Introduce a source with context. A lead-in like "According to…" or "As Meldrum argues…" shows how it connects to your point.
  • Follow up with your own analysis. Explain why it matters or how it supports your claim. That's what your professor is really looking for.
  • Keep a balance. A paper of nothing but quotes leaves your reader wondering what you think.

Quick checklist

  • Every quote, paraphrase, and summary has a note
  • Quotes in quotation marks (or a block quote), with the page
  • Paraphrases in your own words and structure
  • Your own analysis after each source
