By contrast, many people infringe copyright without ever claiming to be the author of the work they are copying. That is, the copier claims to be the original author of those ideas or that work. One of the main differences between these two concepts is that plagiarism always involves one person attempting to present someone else’s thoughts, ideas or expressions as if they were their own original work. Everything will depend on the facts and circumstances of each particular case.

At the same time, if someone copies your work and then presents it as if it was their own they may be guilty of both plagiarism and copyright infringement. Plagiarism can occur without infringing copyright, just as someone can infringe copyright without plagiarising the original author’s work. It is true that both plagiarism and copyright infringement concern inappropriate copying but it is important not to confuse the two concepts. People often discuss plagiarism and copyright infringement as if they were one and the same thing, but that is misleading. Copyright infringement occurs when you make use of an author’s copyright work, without their permission, in a way that is expressly prohibited by law. Plagiarism occurs when you present someone else’s thoughts, ideas or expression as if they were your own, without properly attributing the original author of the work.

Before she was murdered, Mary Westmacott had become increasingly concerned for her safety and state of mind.
