How to Avoid Accidental Plagiarism
Updated
Learning how to avoid accidental plagiarism is mostly about habits during research, not tricks at the end. Most unintentional plagiarism happens when notes mix copied sentences with your own thoughts, or when a source gets forgotten. These steps help you keep track, and a plagiarism check at the end catches what slips through.

How to Avoid Accidental Plagiarism While Researching
- Mark copied text: put anything copied into notes in quotation marks with the source, every time.
- Separate your thoughts: write your own reactions in a different colour or section.
- Record sources immediately: URL, author, title and page number as you go, not at the end.
- Close the source when paraphrasing: write the idea from memory, then check it against the original.
Quoting, Paraphrasing and Common Knowledge
Quote when the exact wording matters, and cite it. Paraphrase when the idea matters more than the words, and cite that too: paraphrasing without a citation is still plagiarism. Facts that are common knowledge in your field usually don't need a citation, but when in doubt, cite.
Changing a few words in someone else's sentence (sometimes called patchwriting) isn't a paraphrase. A real paraphrase uses your own structure and words.
Checking Your Draft
Before submitting, run the plagiarism checker on the full draft (up to 150,000 characters). It lists matching web sources with a match percentage, so you can find passages you forgot to cite or quote.
A match on a quote you cited is fine. A match on a sentence you thought was your own is the one to fix: rewrite it properly or add the citation.
Self-Plagiarism
Reusing your own earlier work without permission can also break academic or publishing rules. If you build on an old essay or article, ask whether it's allowed and cite the earlier piece.
Group Projects and Shared Documents
In group work, ask each member to mark which sections they wrote and which sources they used. Copied text pasted into a shared document by one person becomes everyone's problem at submission time.
Frequently asked questions
