Important to know

Plagiarism checkers are NOT 100% accurate. You still need to use your own judgment when writing and citing.
Review all sections of this module to know why, when, and how to cite. When in doubt, cite!
Be careful while using free software as they may save and sell your paper to essay mills. Other students can use it and you can be accused of plagiarism.
If you are very concerned, you can check your own work with software like Grammarly or EasyBib for a fee.
Ask your professor or a librarian for help when you have any questions or concerns.

Turnitin

Many CSUN professors use Turnitin, an online plagiarism detection tool, to screen student work against a digital database of publications, papers, and websites. If your professor has allowed students to see their Turninit originality report/similarity report, take advantage of it and check your paper for plagiarism before submitting it. You can find more information about accessing and interpreting the report on this webpage from Tufts University and this Turnitin's webpage.
