I have to paraphrase this sentence in one simple sentence: Plagiarism, whether done deliberately or accidentally, is defined as presenting someone else’s work, in whole or in part, as one’s own.  It includes the verbal or written submission of another work without crediting that source.  This applies to ideas, wording, code, graphics, music, and inventions.  It includes all electronic sources, including the Internet, television, video, film, and recordings, all print and written sources, such as books, periodicals, lyrics, government publications, promotional materials, and academic assignments; and all verbal sources such as conversations and interviews.
