Copyright protects the rights of anyone who creates, and/or owns, a piece of work – literary (e.g. books, journals, computer programmes), dramatic, musical or artistic (e.g. drawings, photos, sculptures), sound recordings, films, broadcasts, and the typographical arrangement of published editions.
Any original (ie, not copied from someone else) work qualifies. It is a 'bundle of rights' that is a part of the overall family of 'Intellectual Property Rights'. It has two main areas - 'Moral Rights' and 'Economic Rights'. It means that no-one else may make any form of copy of that work without the permission of the copyright owner or a licence to do so.
