Can you plagiarize your own work?

Although it sounds contradictory, you can indeed plagiarize your own work. This is called self-plagiarism. Self-plagiarism goes against the expectations of the reader that the paper you submitted is new and original.

You can plagiarize yourself by, for instance:

  • Submitting a document you previously submitted for a different course
  • Using ideas or data from a previous paper without correctly citing yourself as the source

Although self-plagiarism is often unintentional, it can have serious consequences. Be sure to cite your previous work or discuss the decision to use your old paper with your professor.
