Copyright is one of a range of intellectual property rights which enables the rights owner to exploit certain types of creative work and control their use for a limited period of time.
Sources of copyright law
In the UK the main source of copyright law is the Copyright, Designs and Patents Act 1988 (CDPA), together with associated regulations. The Act has been amended several times since it was passed by Parliament, so it is important that you consult the most up to date version. Contract law in the form of licence agreements is also important.
