Plagiarism involves presenting another person's ideas or work as one's own. It is considered a form of fraud and theft under US law. Plagiarism can be avoided by properly citing sources, whether the sources are words, ideas, images, videos or music. When writing a research paper, careful planning and note taking is important to distinguish what is your own original work versus ideas and content from other sources. Any uncertain content should be cited to the original source. Consulting with teachers can help clarify any issues or questions about plagiarism.
