From the VMI Writing Center:
"Chances are, you know not to copy and paste articles from the internet and try to pass them off as your own writing. However, plagiarism can happen accidentally through neglect rather than intent when you’re writing. Even if you’ve done it accidentally, the end result is still the same – you’ve plagiarized."
"What’s the best way to avoid plagiarism? Give credit to other people’s ideas and words when they did not come directly from your own brain."
