To prevent others from copying your work, you have to copyright your work. Using someone else’s work without asking for permission is illegal and classed as plagiarism. If you use part of someone else’s work to help argue your case or argue against it, you can reference the work on your essay. You have to state the author, website, article name, year of publication, date accessed and the full url. If you use or quote someone else’s work without referencing it, the tutors and higher markers will think that you are trying to class it as your own work, which can make your work invalid and can fail the work as it would be plagiarism.
